    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 withstood a 10 minute attack from Category A tools such as screwdrivers, pliers and small knives, with each tool given a maximum attack time of 1 minute, providing it with a rating of A1 under Issue 8, the equivalent of SR1 under Issue 7.
