from California– Verified Buyer

These clamps fit perfectly on the bar and work great. The quality for the price was really good as well.


Best investment for garage gym

Ramiro from San Juan, TX– Verified Buyer

Before I purchased these, I had the generic spring collars, which would not hold up very well. These keep the bumpers very stale on the bar, keeping my clients safe.

Even though it says CAP brand its not

Mark from Missouri

The clamps work great! I saved a lot on this buying under the CAP name. This Muscle Clamp is the exact same thing as the more expensive Muscle Driver or York Barbell ones. Same packaging and labels even.
