331 is a heavy-duty, normally open ASSA ABLOY electric strike. It reliably releases the door even under pressure on the leaf of up to 5 kN, so it suits escape doors and airlocks with a pressure differential. The steel construction is rated for millions of cycles, with a break-in resistance of 7.5 kN.
