  • Standard sizes and made-to-measure available (Salisbury design in standard sizes only).

  • The first up and over door available in the UK with full “Secured By Design” accreditation (STS 202 Issue 3: 2011 BR1).
  • When security is important, this is the ideal door.
  • It’s accreditation is due to a number of features outlined below:

Anti-Snap Eurocylinder Lock.

  • If the door lock is attacked, forced or levered the front section of the Eurocylinder, being sacrificial, will fall away.
  • The inner part of the lock, which remains securely locked if such an attack takes place, remains in place below the surface of the door and is very difficult to get to.

Steel Plate Protection of the Lock Body.

  • If an attempt is made to force or cut through the metal door skin adjacent to the door handle, a sturdy metal plate welded behind the lock protects against such an attack.
  • The plate also protects the locking rod anchor points where they are connected to the main lock body.

High Security Bracing on Rear of Door Panel

  • Rather than having the standard 2 horizontal steel bracings welded to the rear of the doors, 8 are now used.
  • If, in the extremely unlikely event of someone “peeling” the steel skin off the front of the door, a person could not climb through the small spacings between the bracings.

Latches with Steel Reinforcing

  • If a burglar attacks the corner(s) of the door and attempts to pry a corner open, steel reinforcement plates prevent distortion of the door or access to the corner latches.

Steel Subframe as Standard (not Timber)

  • All Guardian doors are supplied with a factory-fitted steel goalpost fixing frame.
  • This is much stronger and more resistant to attack than a door mounted to a timber goalpost frame which can splinter or crack.
  • Fixings are also easier to force out of timber.
  • Steel security bolts, rivets and welds are used on the Secure By Design door.
