Protek 358 Clamp

SR1 Rated Security Fence System

Protek 358 Elite is an improved version of our standard prison mesh fencing that is approved to SR1 security standard by the LPBC (Loss Prevention Certification Board).

SR1 security fencing can withstand opportunistic attempts at forced entry using basic tools such as cable cutters, screwdrivers, knives and hammers, for a period of time. This, combined with Protek 358’s tight mesh spacing, creates a security fence that is very hard to climb, cut through or force entry.
