Frequently Asked Questions

Q: What bar size is this spin-lock barbell collar compatible with?

A: This collar is designed exclusively for standard 25mm (1-inch) barbell and dumbbell bars. It is not compatible with Olympic 2-inch bars. Always check your bar diameter before purchasing.

Q: Is this collar sold as a single piece or as a pair?

A: This listing includes one (1) spin-lock barbell collar. If you need a pair to secure both ends of your barbell, we recommend ordering two units.

Q: How does the cam-lock mechanism work?

A: The single-action cam-lock clamps onto the bar with a simple press-and-twist motion. It creates a firm, stable grip that keeps weight plates securely in place during your workout, and releases just as easily when you're ready to change weights.

Q: Is this collar suitable for heavy lifting?

A: Yes — the solid stainless steel construction and chrome finish are engineered for durability and consistent performance across toning exercises, strength training, and general gym use on standard-size bars.
