Surface-Mounted Door Security Bolts
Barrel bolts add a simple sliding fastening to doors, gates, cupboards and storage areas. MacBlair stocks straight barrel bolts in 50mm and 76mm sizes, alongside a 100mm black tower bolt and a 150mm zinc-plated padbolt.
Choose the bolt length to suit the weight and construction of the door. Surface mounting keeps installation uncomplicated, but the bolt and receiver must line up cleanly so the shoot moves without binding. The full locks and latches range covers other closing and security arrangements.
Use suitable screws and fix into sound timber or a correctly prepared substrate. If the same job includes replacing door handles and lever furniture, check the finish before ordering. Worn doors may also need new door hinges to restore alignment before the bolt is fitted.
