Numerous Thermo46 models, depending on the amount of glass in the door, come with Secure by Design security accreditation. Take a look why:
  • Double throw steel locking bar. When the key is turned and turned again the hardened steel locking bars locate deep into the frame.
  • Steel conical swing bolts and security bolts. Steel swing bolts and bevelled security bolts top and bottom locate into the frame and gently seal the door to the frame.
  • Soft latch is reassuringly quiet and strong. Soft latch engages quietly when the door is closed adding quality “sound” to the door, like closing the door on a quality car.
  • Hinge side security bolts locate into the frame. Three steel security bolts on the door leaf locate into the frame behind the hinges ensuring that the hinge side of the door is very secure as well. The hinge side is the most vulnerable on most doors, but not on the Thermo46 range.
