This roller buckle is perfect for a belt buckle, harness buckle, mens belt buckle, womens belt buckle, dog collar buckle or strap buckle. The buckle roller allows for easy tightening of the leather strap. The 1 3/4 inch size is the inside diameter so you know how much space you have for your leather.
This buckle is of good quality and overall a very nice buckle. But it is NOT 1 3/4", it is a full 2" buckle, do NOT buy it for a project requiring 1 3/4"
