The Brio 456 range of flush bolts is ideal for securing bifolding and sliding panels. The classic square cut of the 456 range works well with traditional joinery, while the round top of the 456R range is designed for modern joinery using CNC routers. Both use a low profile design which reduces rebate depth and maintains strength of the timber stile. Suitable for inward and outward opening bifolds, French doors, and top hung or bottom rolling sliding panels, the 456 range comes in locking and non-locking versions, offering flexible security you can rely on.
