Plastic side‑release buckle for 15mm (5/8") webbing. A versatile closure for luggage, backpacks, belts and totes, it opens with side tabs and locks with an audible click. Use with a matching tri‑glide or ladderlock when strap length needs adjustment. The low‑profile shape keeps hardware streamlined on finished projects and works with most nylon or polyester webbing for daily use.
