How It Compares
Compared With Cylinder locks
A barrel bolt secures a door that is bolted from one side only, and it keeps working when a lock mechanism would have seized in a dusty outbuilding.
Use Guide
- Mount the case on the door and the strike on the frame so the bolt enters squarely.
- Allow a small clearance so the bolt still throws after the door has swelled in wet weather.
