Caldwell's rugged locking mechanism for bi-fold doors can be fitted to secure folding door sets in the closed position. The gearbox drives a sturdy 10mm wide shootbolt from the traffic door so it can’t be forced open. This delivers PAS 24 certified security performance that meets Document Q requirements for new builds and brings added peace of mind to homeowners.
