Yale Lockmaster cropped

We offer a choice of 6 locks, although the Yale Lockmaster is our standard offering

The Lockmaster is a multi-point lock that has been designed, developed and tested in the UK to deliver the highest levels of performance, so installers can offer security and peace of mind to homeowners. With Secured by Design accreditation, the Lockmaster features a combination of hooks and anti-lift bolts for greater security. BBA certified for security, performance and corrosion resistance, the Lockmaster comes with a 10 year guarantee, while its 15 year service history proves a high level of reliability. It also comes with 5 keys.

yale keyfree

The Lockmaster is fully compatible with the Yale Keyfree - which allows homeowners access to their property without a key, using a remote fob or secure PIN code. Yale key free gives you key pad and remote fob access control to your door. Introduced by Door-Stop in 2010, the Yale key free handle is completely wire free, alarmed, and still combines police approved secured by design security.

stainless steel knockers

Stainless steel furniture as standard

The latest evolution in door furniture is now supplied on Door-Stop doors, as standard. With the external furniture now manufactured from 304 grade stainless steel you can now give your customers a 10 year anti corrosion guarantee, and because this is the same grade of material used for making sinks, its a guarantee that you won't expect to use!

Our stainless style extends to polished gold, chrome and black finishes on handles, letter plates, knockers and numerals. The furniture fitted to the inside of the door is the same colour and manufactured with a zinc PVD finish. The lever/lever and lever/pad handles incorporate a spring cassette to eliminate any dropping and has been tested to 50,000 cycles, whilst the urn knocker is face fixed to remove the need for fixings on the inside of the door.

The letter plate opens to 180 degrees and even the return spring is stainless steel which was cycle tested to 100,000 operations. The external flap houses a peripheral seal that also forms a full thermal and acoustic barrier. So, for water resistant furniture equal to that of our GRP skins, how much extra are we charging... nothing.
