'Hydra SD1'

Level 1 Security Steel Hinged Door.

Specification: -

The `SD1` doors are suitable for medium risk applications and resist professional attack with a variety of hand tools for up to 5 minutes.

Each door is constructed from corrosion resistant `Galvaneal` sheets and are manufactured using a weld free technique, the attack resistant leaf consisting of two 1.5mm thick steel skins fabricated into a door blade. The overall door blade is 44mm thick, in-filled with small cell honeycomb core material.

3No specially modified stainless steel dog bolt hinges are used for additional security, even if the hinges are physically attacked the dog bolts prevent the door being removed from the opening. To prevent the door leaf being jemmied open they are supplied with an integral astragal.

Adjustable fixing feet allow standard width doors to be used in non-standard width openings when used in conjunction with our variable sub frame system. Variable sub-frame is used to minimise and neaten the mastic gap around the doors. The sub-frame also protects the fixing points from attack.
