Security Certified Doors

Chainless Limiter

In pursuit of increased security, all ZENTRY doors can include our unique Chainless Door limiter. This remarkable technology enables the occupier to slightly open a door which must be closed shut and again opened, prior to allowing entry.

Our Chainless Door Limiter is installed in the internal cavity of the door and provides increased security for the discerning home owner.

This major innovation increases the door resistance against external forces and particularly in cases where attempts are made to force the door open.

This system has obvious advantages over traditional door chain systems, where the cutting of the visible chain by an intruder, provides immediate access to the building.
