Multi-point locks are pretty self-explanatory: they bolt the door at multiple points. Typically, entry doors on a home will have a 1-inch deadbolt but this isn’t enough to keep a door secure against a basic attack such as being kicked in. Why?
- One locking point is not enough to withstand a basic attack.
- Wooden door jambs are weak and vulnerable.
The physics behind a multi-point lock is simple: it distributes the pressure of a brute force attack (such as a kick-in) across multiple locking points instead of being absorbed by a single point, like a 1-inch deadbolt. By dispersing the force across multiple locking points, a door can resist more impacts and more pressure.
There are many different multi-point locks on the market, and these locks should never be judged simply by the number of bolts they have because there are many different ways to attack a lock that does not involve pure brute force.
Multi-point locks are essential in any high-security door and at Shield, we offer two types: the Mottura 85 series mechanical lock and the Fiam X1R motorized lock.
