The Gorila Proloc 2 Chain/band is a high-strength nylon collar designed to fit any bar with a diameter ranging from 1.937" to 2.007". It is compatible with Olympic bars, powerlifting bars, and most logs, cambered bars, Swiss bars, and safety squat yoke bars.

Sold in sets of two, these collars can support a tested 675 pounds of chains per collar, making training with them extremely flexible. They are also incredibly durable and can withstand even the hardest gym environments for years. Note that while they can fit smaller bars, they are not recommended for use as collars but rather as chain holders.
