Security, as a complete system.
Understand the door, the lock and the evidence behind them.
More than one lock.
Security depends on the complete doorset: leaf, frame, glazing, hinges, cylinder, locking system and installation. Our doors come with the Yale Lockmaster; the Ultion Sold Secure Diamond cylinder and a Secured by Design door are options to ask HHI about.
Check the claim against your door.
Product certification applies to a tested configuration. Company or installer membership is a different kind of assurance. Before you order, ask HHI for the certificate that covers your exact door.

Choosing for a flat or shared building.
A standard composite door is not a fire door. Fire doors must be specified and installed as a complete approved doorset. HHI must confirm the applicable fire, smoke, hardware and installation requirements for the property.
