Clear side-release buckles:
This clear side-release buckle is constructed from a clear polycarbonate plastic (PC). PC is an extremely strong, lightweight, and stable plastic material that is used widely from bullet-proof windows, to compact discs and computers, to greenhouse walls, to automobile headlamps. Unlike other plastic materials, PC is heat-resistant and shatterproof.
The side-release buckle on this collar comes with a measured breaking strength. Typically, dogs are able to apply 2X their body weight on the buckle clasp of their collar. With this in mind, the clear side-release buckle holds to the below strengths:

1" - 150 lbs
1 1/4" - 165 lbs
