ZEROplus Lockcases 7200 Series

7200 Series is a range of high quality heavy-duty Euro Profile lock cases, with 60mm backset and 72mm centres. Manufactured in accordance with DIN 18251. Modular in design meaning one door prep suits all functions. The range offers a heavy sprung Stainless Steel clamping follower, solid stainless steel latch & deadbolts, reversible latchbolt and a one piece stainless steel square or radius forend. The latchbolt is light sprung for easy operation and is also guided, while the deadbolt has a 20mm double throw. The existing range offers the four main functions; sashlock, deadlock, latch & nightlatch with an escape lock coming soon.

These locks have been fire tested on 30 minute and 60 minute Timber doors and 60 minute steel doors. All four functions have been positively assessed for use on previously tested insulated timber Doorsets or uninsulated steel doorsets to provide up to 30 minutes and 60 minutes integrity in accordance with BS EN 1634-1: 2000 in the proposed configuration i.e. Single-leaf or double-leaf.

A complete Zero ZLP44 intumescent lock pack (see here) must be used for 60 minute fire resistance on timber doors. For 30 minute timber doors the lockcase does not need intumescent protection, but ZLP44-812 intumescent should be fitted behind the lock forend and ZLP44-675 behind the strike plate. No intumescent is required round locks or behind strike plates on steel doors.
