Great product! Fast shipping.
Love this product. Great design. Makes changing barbell plates fast and easy.
ConsA little on the price side. Also, wish it weren't made of plastic. If they were made of steel or metal, it would justify the price.

These collars are wonderful! They go on easy, come off easy, and lock easily. I bought several pairs of them, both in the 1"; and 2"; sizes. These collars work so well and are so quick to get on and off that I will never order another type of collar again.
ProsFAST on and off application. They work VERY well!
ConsPrice is a little steep, especially since the collars are made up of some type of plastic.

Lock jaw 1" collars
These are the perfect collars for standard dumbbell handles. They really sped up my time in changing weights between sets.
