Multi point locks
Multi point locking systems are predominantly found within UPVC and composite doors but can also be found in timber and aluminium doors. They will have a latch, deadbolt and three or more locking points which will secure the door within the frame by operating both the handle and the lock (Euro cylinder) providing a tight weatherproof seal. The locking points will either be exclusively or a combination of roller cams, roller mushrooms, hook bolts, dead bolts, wedge bolts, pins or top & bottom shoot bolts.
Multi point locking systems are one of the most secure door locking systems available. Like any lock though, multipoint locking systems are subject to a limited lifespan due to age and wear and tear. At the end of their lifespan these locks have the potential to fail causing properties to be unsecure or can leave homeowners locked out or locked in their properties. There are several warning signs which can indicate when a multi point lock is reaching the end of its lifespan which we have listed below.
When operated the handle makes a clunking or grinding sound.
Not all locking points operate when the handle is lifted
The handle is drooping
The door cannot be locked when the handle is lifted
The handle is loose
Excessive force is needed to lift the handle
The key will not completely turn
Most of the examples mentioned above indicate a faulty multi point lock but can also relate to other issues such as a misaligned door or a worn handle cassette all of which we can rectify here at Selkent Glazing & Locks. If your door has any of the issues mentioned above then give us a call today.
