Use Sea to Summit's Field Repair Buckles to quickly and easily repair buckles while you're in the field. Buckles are secured with stainless steel screws, so there is no need to have the replacement buckles sewn on later. The ladderlock replaces ladderlock buckles found on backpack shoulder straps and compression straps. One-pin side-release buckles replace single-adjustable side-release buckles found on most top-loading backpacks and compression straps. Two-pin side-release buckles replace nonadjustable buckles found on dry-bag closures and V-pull-style waistbelts. Available: 1" Ladderlock, 1-Pin, 2-Pin, 3/4" Ladderlock, 3/4" 1-Pin, 3/4" 2-Pin.
