Body-Solid 5 lb Weight Stack Adapter Plate WSA5 5lbs for Selector Stacks, Steel Core with Rubber Jacket

Body-Solid WSA5 is a 5-pound weight stack adapter plate that clips onto compatible weight stacks so you can increase resistance in precise 5 lb increments.

If your machine jumps by large weight increments, the Body-Solid 5 lb Weight Stack Adapter Plate (WSA5) lets you fine-tune resistance on many commercial and home gym weight stacks. Built with a steel core wrapped in protective rubber, the adapter fits common selector-style stacks and Smith/cable machines so you can progress in smaller steps without buying new plates or machines.

How does the WSA5 attach to my existing weight stack?

Installation is simple and tool-free on most selector-style stacks: the adapter slips over a single weight plate or around the selector pin area depending on your machine, then locks into place so it travels with the stack when you lift. It’s made to be secure during normal exercise motion and easy to remove when not needed.

• Fits many Smith machines, cable machines, functional trainers and other selector stacks.
• Solid steel core ensures a stable, non-wobbling attachment.
• Virgin rubber moulding protects plates and reduces noise.
• Quick on/off—no tools required for most setups.

What are the materials and dimensions of this adapter?

The WSA5 combines a dense steel core with a thick, protective rubber exterior to resist wear and protect equipment finish. It’s compact and travel-friendly, designed to add five pounds without taking significant storage space.

• Overall size: approximately 4 x 5 x 1.5 inches—low profile for tight stacks.
• Steel center for strength and consistent lift behavior.
• Durable rubber jacket to prevent scratching and reduce clanking noise.
• Lightweight enough to carry in your gym bag but heavy enough to stay secure on the stack.

Will adding a 5 lb adapter affect exercise safety or performance?

When used as designed with compatible stacks, the adapter provides consistent incremental resistance without altering the machine’s biomechanics. Because it moves with the selected stack piece, it does not change pulley angles or range of motion—just the load you feel.

• Maintains original stack alignment and pulley geometry.
• Reduces abrupt jumps in resistance to support progressive overload.
• Protective rubber reduces noise and contact wear during lifts.
• Always verify compatibility and secure fit before every session.

How easy is it to store and carry the WSA5 between workouts?

The compact footprint and lightweight design make the WSA5 simple to stow in a locker or training bag. It doesn’t require a dedicated rack or extra storage and can be left attached to the stack when not in use if you prefer quick access.

• Small enough to tuck into gym storage or a duffel bag.
• No separate mounting hardware that needs organized storage.
• Can be used on multiple machines, minimizing the number of adapters needed.
• Durable finish resists scuffs during transport.

Who is this for: The Body-Solid WSA5 is designed for lifters who want finer control over progression—beginners stepping up from bodyweight, intermediate athletes who need smaller jumps to break plateaus, and trainers managing multiple clients with different strength levels. It’s ideal for home gym owners and fitness facilities that use selectorized stacks and want a compact, durable, and cost-effective way to refine resistance without replacing equipment.
