4 cm / 1.57 in Plastic Snap Buckle for 40 mm Webbing
This 4 cm / 1.57 in snap bandolier buckle is used to open and close wider strap systems. It can be used on bags, backpacks, school bags, work bags, sports bags, belts, aprons, workwear, tarpaulins, promotional products and textile accessories where 40 mm webbing is used.
The verified webbing use is 4 cm / 40 mm. The locked outside length is 69.5 mm / 2.74 in, and the outside width is 50.5 mm / 1.99 in. Actual webbing width, thickness, stiffness and folding should be checked before bulk production.
How It Works in a Strap System
This product belongs to the Bag Buckles, Rings and Hooks family. It should be compared with Side Release Buckles and Slide Adjusters when buyers select buckle options by strap width, material and final application.
This buckle provides the fastening function. It does not adjust strap length by itself. When length control is needed, a matching 4 cm / 1.57 in ladder buckle or strap adjustment buckle should be added. If the strap system needs a fixed connection point, a D ring, O ring or frame buckle should be selected according to the same strap width.
Why This Buckle Is Useful
- Fits 4 cm / 40 mm webbing.
- Provides a quick open-and-close side-release function.
- Plastic body keeps wider strap systems lighter than metal hardware.
- Useful for bags, backpacks, tarpaulins, aprons, workwear and promotional products.
- Available in black, white, navy, red and yellow options.
- Can be compared with 4 cm curved plastic snap buckles and 4 cm strap adjusters.
Choosing Similar Buckles
For another 40 mm plastic fastening option, a 4 cm curved plastic snap buckle can be compared. If the same strap system needs length adjustment, a 4 cm plastic ladder buckle should be added. For smaller webbing systems, 3 cm, 2.5 cm and 2 cm plastic snap buckles can be selected according to actual strap width.
If a wider strap layout is required, a 5 cm / 1.97 in top-lock side-release buckle can be selected. The final choice should be based on strap width, strap thickness, expected load and the desired buckle body size.
