Roto H500 Passive Genuine Multipoint Gearbox – Lift Lever

This Elite Standard gearbox is suitable for a passive door on a pair of French doors.

Passive locks are fitted to the secondary (or passive) door on a pair of French doors. They are used in conjunction with the primary lock, which is a normal multipoint door lock, fitted to the main door. Locking is achieved by shoot bolts which secure the secondary door leaf to the frame when the door is locked.
