The best cable machine weight add-on for most stacks is the Body-Solid Weight Stack Adapter Plates, because it adds resistance in 2.5 lb increments and is designed for weight stack machines. For a smaller jump, compare 2.5 lb options; for a machine-specific fit, start with the model compatibility and measurements.
An add-on weight fills the gap between the stack settings your machine provides. The right cable machine add on weight must match both the increment you want and the way your machine accepts extra resistance.

How we chose cable machine add-on weights
We compared the stated increments, attachment styles, fit measurements and machine compatibility for each option. Our score weighs specs, features and buyer feedback against what you're shopping for.
Check whether an option is made for selectorized stacks, sits on the top plate, or attaches to a selector pin. If the fit details do not match your machine, choose another style rather than assuming a universal fit.
Compare add-on weights for cable machines
The main tradeoff is between smaller increments and fit specificity. Use the table to narrow your options, then confirm measurements and compatibility for your machine.

Best add-on weights for cable machines
These picks are listed from highest score to lowest. The first options focus on smaller stack increases, while later picks suit a specific attachment style, weight increment or machine family.
StrengthUSA 2.5 LB and 5 LB Weight: Best for combining small increments
- 2.5 lb plate
- Steel construction
- Slides onto a selector pin or stack attachment
- Can combine with 5 lb add-on weights
A 2.5 lb plate gives smaller increases than a typical 5 lb add-on. It can also be combined with a 5 lb weight to make different increments.
Pros
- Small 2.5 lb increase
- Designed for selector pins or stack attachments
- Can pair with 5 lb add-on weights
Cons
- Confirm fit with your stack attachment
StrengthUSA is the most flexible pick here for building smaller resistance changes. Its 2.5 lb plate slides onto a selector pin or stack attachment, and it can be combined with a 5 lb add-on weight for a different increment.
The plate is made from alloy steel and has a powder-coated finish. Its compact format also makes it easier to store beside other home gym accessories when it is not on the machine.
Before using it, check that your stack attachment has enough room for the plate and that it can sit securely. A small add-on should not obstruct the selector pin or interfere with stack movement.
Choose this when you want to bridge a larger gap between stack settings with a 2.5 lb increase. If your machine uses a proprietary top plate or a different attachment, confirm compatibility first.
Body-Solid Weight Stack Adapter Plates: Best for 2.5 lb stack increments
- Adds 2.5 lb
- Rubber over a solid steel core
- Designed for weight stacks
- Dimensions: 4 x 5 x 1.5 in
This 2.5 lb adapter is a direct option for making smaller changes on a weight stack. Its stated fit covers weight stack machines, including cable machines and functional trainers.
Pros
- 2.5 lb increase
- Broad stated weight stack compatibility
- Compact dimensions
Cons
- Check that its shape clears your machine
Body-Solid is a strong general choice for a 2.5 lb increase on a weight stack. Its adapter uses rubber molded over a solid steel core and measures 4 x 5 x 1.5 in.
The stated fit includes weight stack machines such as cable machines and functional trainers. That broad description is useful, but it does not replace checking the shape and clearance of your particular stack.
A 2.5 lb change can make progression more gradual than moving to the next full stack plate. If your machine already has small increments, compare those settings with the add-on before adding more resistance.
Choose this when you want a compact adapter with an explicit 2.5 lb increment. For a broader overview of compatible plate options, see Best Weight Plates For Functional Trainer.
Power Systems Selectorized Machine Add-On Weight: Best for U-shaped 5 lb add-ons
- 5 lb weight
- U-shaped design
- Rubber-coated cast iron
- Maximum 3.25 in between guide rods and 2 in post diameter
This U-shaped weight is made for selectorized machines. Measure the guide rod spacing and post before choosing it.
Pros
- Clear fit measurements
- U-shaped attachable design
- Rubber-coated cast iron
Cons
- Adds 5 lb rather than a smaller increment
Power Systems suits machines where a U-shaped add-on can fit around the stack hardware. The rubber-coated cast iron weight adds 5 lb and is sold individually.
Its fit has two useful measurements: the maximum width between guide rods is 3.25 in, and the post diameter is 2 in. Measure both points on your machine before choosing this style.
A U-shaped weight is different from a plate that rests on top of the stack. If you are comparing attachment types, this guide to what a weight horn on a cable machine does can help you identify a separate loading point.
Choose this for a selectorized machine that matches the dimensions and needs a 5 lb jump. If you want a smaller change, consider a 2.5 lb adapter instead.
July Body 1.25 Pound Weight Clips: Best for free weights
- Two clips
- 1.25 lb per clip
- Designed for dumbbells, kettlebells and barbells
These clips add small increments to free weights. They are not described as cable machine stack attachments, so use them for compatible dumbbells, kettlebells or barbells instead.
Pros
- Small increase per clip
- Works with several free weight types
- Compact two-clip pack
Cons
- Not a cable stack add-on
July Body's two clips add 1.25 lb each and are described for dumbbells, kettlebells and barbells. For handles that take loadable plates, see loadable dumbbell handles.
That makes them useful for fractional loading on free weights, but they are not a cable stack add-on.
Keep this distinction in mind when searching for an add on weight for cable machine use. A clip that fits a dumbbell handle does not automatically attach safely to a selectorized stack or cable machine accessory.
If you are shopping for a cable setup, choose a weight designed for the stack or a compatible attachment. For free-weight loading, compare Olympic loadable dumbbell handles.
This pick makes sense only if your training also includes the free weights named for it.
Choose July Body for small increases on compatible dumbbells, kettlebells or barbells. Skip it as a substitute for a weight stack adapter.
Ader Sporting Goods Add On Weight 2.5: Best for a 5 lb rubber adapter
- 5 lb adapter plate
- Rubber material
- Stated for home gym exercise
This Ader option is a 5 lb stack adapter made from rubber. Confirm the shape and attachment fit with your machine before ordering.
Pros
- Simple 5 lb increment
- Rubber material
- Designed as a stack adapter
Cons
- Fit measurements are not specified here
Ader Sporting Goods offers a rubber 5 lb weight stack adapter for home gym exercise. Its title mentions 2.5 lb or 5 lb options, but this version is identified as a 5 lb adapter.
The product data does not give fit measurements. Check your machine’s stack shape and available clearance, and make sure the adapter remains secure throughout the cable’s range of motion.
This choice suits a home gym where a 5 lb jump fits your progression. If you need a smaller increase, compare the 2.5 lb options earlier in this guide.
Choose this when the 5 lb version and rubber construction fit your setup. Measure first because compatibility dimensions are not specified here.
IVANKO ADD ON PLATE: Best for a measured top plate
- 5 lb plate
- Rubber-encased machined cast iron
- Fits on top of a weight stack
- Not compatible with Inspire Fitness FTX
This 5 lb plate sits on top of a machine's weight stack. Check its dimensions against your stack and avoid it for the Inspire Fitness FTX.
Pros
- Top-stack placement is stated
- Rubber-encased cast iron
- Fit dimensions are available for checking
Cons
- Not compatible with Inspire Fitness FTX
The Ivanko AOP-5 is a 5 lb add-on plate designed to sit on top of a machine’s weight stack. For plate choices for adjustable dumbbells, see cast iron dumbbell plates.
It uses rubber-encased machined cast iron, and its fit depends on the dimensions of your stack and top plate.
Ivanko specifically notes that this plate is not compatible with the Inspire Fitness FTX. If you own that model, use an alternative designed for it, such as the Inspire add-on later in this list.
Think of a top plate as a distinct mounting surface. Before adding a plate, identify what a weight plate is and compare its size with the part of the stack it will rest on.
Choose Ivanko when your stack dimensions match and you want a 5 lb top-mounted increase. Do not use it on an Inspire Fitness FTX.
Ader Add On Weight Stack Adapter Add: Best for 5 in guide rod spacing
- 5 lb add-on plate
- Rubber material
- Requires guide rods 5 in apart center to center
This 5 lb Ader adapter has a useful fit check: its two guide rods need to be 5 in apart from center to center. Measure before choosing it.
Pros
- Clear guide rod spacing requirement
- 5 lb increment
- Designed for home gym machines
Cons
- Requires a specific guide rod spacing
This Ader 5 lb adapter has a clear spacing requirement: its two guide rods need to be 5 in apart, measured center to center. It is made from rubber and is intended for a home gym machine or universal gym attachment.
That measurement makes the fit check straightforward. Measure between the centers of the rods, not from one outer edge to the other, and confirm the weight can sit without catching as the stack moves.
A crooked or misaligned stack can affect clearance. Review why a cable machine weight stack may be crooked before adding an accessory if your plates already sit unevenly.
Choose this Ader model when the guide rod spacing matches and a 5 lb increment works for you. If your spacing differs, pick another adapter with a compatible fit.
Inspire Fitness 5 lb Add-On Weight: Best for listed Inspire models
- Adds 5 lb
- Fits Inspire Fitness FTX, FT1, FT2, SCS, M1, M2, M3 and M5
- No tools required
- Measures 4 x 5 in
This add-on is designed for named Inspire Fitness home gym models. It offers a straightforward 5 lb increase without tools.
Pros
- Named compatible models
- No tools required
- Compact 4 x 5 in size
Cons
- Compatibility is specific to listed Inspire models
The Inspire Fitness add-on is designed for specific models: FTX, FT1, FT2, SCS, M1, M2, M3 and M5. It adds 5 lb, measures 4 x 5 in and can be added or removed without tools.
Its named model list makes it the clearest option for owners of those Inspire machines. For a dual weight stack system, order two add-on weights.
Choose this when your machine appears in the compatible model list and a 5 lb change suits your training. If you have a different model, verify fit with Inspire before choosing it.
For broader equipment context, compare plate-loaded vs weight-stack functional trainers, since the way a machine holds resistance affects which add-on styles can work.
Which types of weight stack add plate should you choose?
The main types of weight stack add plate are selector-pin adapters, U-shaped weights and plates that rest on top of the stack. For a rack-based cable setup, compare pulley systems for home gym racks as another way to add cable resistance.
For a tower setup, see cable tower foot plates for added foot support. Choose the style that matches your machine’s attachment point and available clearance.
A selector-pin adapter is useful when the machine provides a compatible pin or attachment. A U-shaped add-on may fit around guide rods or a post, while a top plate needs a matching stack surface.
For smaller resistance changes, look first at 2.5 lb options. A 5 lb add-on can work when that jump matches your training, but it may not solve the problem if the regular stack increments are already large.
How can you check fit before buying?
Measure your machine where the add-on will sit or attach. Check guide rod spacing, post diameter, stack top dimensions and clearance through the full range of motion.
Product-specific measurements matter: Power Systems gives a 3.25 in maximum width between guide rods and a 2 in post diameter, while the Ader adapter requires guide rods 5 in apart center to center. Do not treat those dimensions as interchangeable.
Also check whether your functional trainer has one or two stacks. If the left and right sides need equal loading, verify whether you need one add-on per side.
Are add-on weights better than changing the stack?
An add-on weight is useful when your current stack jumps are too large for the next step in your training. It adds a smaller increment without requiring you to replace the machine’s plates.
Some machines use pin-selected stacks, while others are plate-loaded. Those systems need different accessories, so compare the machine design before choosing an add-on.
Which cable machine weight add-on should you choose?
Choose StrengthUSA or Body-Solid if you want a 2.5 lb increase, and select the one whose attachment style fits your stack. Pick Power Systems or a compatible 5 lb adapter when your machine matches the required measurements; choose Inspire for one of its named models.
Before ordering, match the add-on to the stack, confirm its increment and check that it clears the machine in motion. For a functional trainer, the best cable machine weight add on is the one that fits your exact stack securely.

Frequently asked questions
What is a cable machine weight add-on?
A cable machine weight add-on increases resistance without changing the main stack plates. Some hang from or sit on a stack, while others fit a selector pin or a specific machine attachment.
Check how the add-on attaches and measure your machine before buying.
How do I choose an add-on weight for a cable machine?
Match the attachment style and measurements to your machine, then choose an increment that suits your training. A 2.5 lb add-on makes a smaller jump than a 5 lb one.
Check the manufacturer’s compatibility information for your exact stack or functional trainer model.
Can I use weight clips on a cable machine?
Only if the clips are designed for the machine’s attachment point. The July Body clips here are described for dumbbells, kettlebells and barbells, not selectorized cable stacks.
For a cable machine, choose an add-on made for weight stacks or the machine’s specified accessory.
What measurements should I check before buying?
Measure the parts the add-on must fit, such as guide rod spacing, post diameter, stack top shape or selector pin attachment. Some weights give specific requirements, including 5 in center-to-center spacing or a maximum width between guide rods.
Check clearance through the stack’s full travel.
