3D printed (PETG), this hook is very stiff. With the central part made of a 2mm 316 stainless steel plate, this hook is much more resistant and durable than a 100% plastic hook.
This hook is designed to slip on the strap of your belt leash or on a harness whose dimensions correspond.
3 strap sizes available : 40mm, 50mm (photos) and 60mm and 2 thicknesses 3mm & 6mm.
If the dimensions do not match your strap, custom hook possible, contact me.
