Snap Buckle 4 cm / 1.57 in Curved Plastic Snap Buckle AL04010

Curved Plastic Snap Buckle for 40 mm Webbing

This 4 cm / 1.57 in curved plastic snap buckle is designed for wider strap systems that need an open-and-close fastening function. It can be used on bags, backpacks, school bags, work bags, sports bags, belts, aprons, workwear, tarpaulins, outdoor gear, promotional products and textile accessories.

The verified webbing use is 4 cm / 40 mm. The product page lists the product type as a side push buckle and the material as plastic. The outside length and outside width fields appear empty on the page, so these values should not be estimated in the product description.

What Makes the Curved Body Useful?

The curved body form gives the buckle a more rounded and ergonomic appearance compared with flat plastic buckles in the same size class. This can be useful in wide bag straps, utility straps, tarpaulin ties and workwear products where a larger buckle body is visible on the final product.

This product belongs to the Bag Buckles, Rings and Hooks product family. Similar fastening buckles can be compared under Side Release Buckles and Slide Adjusters according to strap width, body shape and final application.

How It Fits Into a Strap Hardware System

This buckle provides the opening and closing function. It does not adjust strap length by itself. If length control is required, a matching 4 cm / 1.57 in ladder buckle or strap adjuster 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.

For a flat body in the same size class, the 4 cm / 1.57 in plastic bandolier buckle can be compared. For narrower webbing systems, 3 cm / 1.18 in, 2.5 cm / 1 in and 2 cm / 0.79 in plastic snap buckles should be selected according to actual webbing width.
