Do I need SR1 fencing?
A1/SR1 fencing is LPS 1175 certified and has been tested to withstand opportunistic attempts at forced entry using basic tools or physical force, for a limited time. It is generally used around schools, commercial properties, and high value residential properties that need increased protection. If you just require a non-tested version of fencing that is still renowned for being the most secure on the market, check out the equivalent product, Sentry.

About A1 (SR1) Fencing
A1 fencing has been tested and certified to provide the minimum level of protection against opportunistic attacks after undergoing the LPS 1175 test devised by LPCB. During testing our fencing had to delay several attacks using category A tools such as screwdrivers, pliers, and small knives, each lasting at least 1 minute, providing it with a rating of A1 under Issue 8, the equivalent of SR1 under Issue 7.
