'Hydra SD4'
Level 4 Security Steel Hinged Door.
Specification: -
The `SD4` doors are suitable for medium to high risk applications and resist professional attack with a variety of hand tools and battery power tools for up to 30 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 solid timber core.
Factory applied primer finish, or optional polyester powder coat finish can be used to colour our door sets to fit in with your design criteria.
We can use High Security triple point ASSA locks with security cylinders and anti-attack shrouds or high security multipoint panic furniture from Surelock McGill .
3No specially modified stainless steel dog bolt hinges are used for additional security, even if the hinge is physically attacked the dog bolts prevent the door being removed from the opening. To prevent the door leaf being jemmied open it is supplied with a heavy duty 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.
