This roller buckle is perfect for a belt buckle, harness buckle, mens belt buckle, womens belt buckle, dog collar buckle or strap buckle. The 3/4 inch size is the inside diameter so you know how much space you have for your leather.
This is a nice solid buckle and should work just fine for any project requiring a strong buckle. Well made with a nice brass finish. The tongue is held into the center of the buckle via rings on either side. I will be ordering more of these shortly once I confirm how many more are needed.
