    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.
