Zanda Heavy Duty Roller Bolt

The Zanda Heavy Duty Roller Bolt is a robust mortice lock suited to both internal and external doors. The roller mechanism allows the door to snap closed against the strike and pull open smoothly, making it a practical choice for high-traffic areas.

Because the deadbolt locks by key on both the exterior and interior, this lock adds security to entrance doors fitted with glass panels. If an intruder smashes a window to reach inside, they cannot undo the key lock to gain entry.
