4 cm / 1.6 in Plastic Hump Ladder Buckle for 40 mm Webbing
This plastic hump ladder buckle is designed for 40 mm strap systems that require strap length adjustment. It can be used on backpacks, sports bags, travel bags, baby carrier straps, camping gear, safety vests, workwear, aprons, outdoor textile products and handmade accessories.
The product belongs to the Bag Buckles, Rings and Hooks family. Strap adjusters, D rings and fixed connection hardware can be compared under D Rings, O Rings and Strap Adjustment Buckles.
Difference Between a Ladder Buckle and a Side-Release Buckle
This product adjusts and secures strap length. It does not open and close like a side-release buckle. If the product also needs a fastening point, a 4 cm / 1.57 in plastic snap buckle should be used together with the ladder buckle. If the strap system needs a fixed loop, a D ring or O ring should be selected according to the same strap class.
Size and Fit Check
The verified band width is 40 mm, and the outer dimensions are 50 mm x 51 mm. Webbing thickness, stiffness and surface texture can affect how securely the strap holds in the buckle. Always test the actual webbing before bulk production, especially for baby carriers, camping gear, workwear and load-bearing bag straps.
