These buckles are made of acetal plastic and they are as tough as it gets. They were originally designed for military use.
The slot on the female half of the buckle allows "no-sew" installation. Stash an extra buckle in your pocket and you have an easy way to repair broken gear while adventuring.
Sold in a package of 2 pair.
Simple reliable and rugged very light weight and minimal easily carry in my tool bag with peace of mind knowing I can easily swap out a buckle on the trail.
Great replacement part for a great strap
This buckle is for the lighter straps and appears to be very well made. Will probably never need these spares but glad to have some!
