The Grosvenor Upvc door is by far one of the most secure doors on the market. With 8” points of locking as standard the protect door lock has been designed to fulfil two purposes, to keep intruders out and also give a lifetime of use. With this in mind the lock incorporates steel hooks and linear bolts at the top and bottom of the door with a soft closing latch and a centre deadbolt plus two locking cams. Finally to ensure all our locks exceed the highest security ratings we use the latest ABS Mk3 barrel which is Sold Secure Diamond SS312 and British Standard TS007 3 Star rated. This gives you Snap secure, Anti- drill, Anti- Bump, Anti- pick and Police Approved, Secured By Design.
