What you need

Step 1 Determining the correct buckle size

To determine the correct buckle size, measure the webbing with a measuring tape. For example, if the webbing has a width of 16 mm, you will also need a buckle that matches this size.

Step 6

Briefly burn both ends of the webbing to prevent it from fraying later. Lightly press the melted edge with a non-flammable object (e.g., with pliers).
Caution: Direct contact with the flame or overheated material can cause burns to the skin.
Always keep the lighter moving and do not hold it in one place for too long to avoid overheating, burning, or excessive melting of the material. Move the lighter parallel to the edge of the material.
