Millenco Mantis 1 multipoint door locks are the original Millenco locks. They feature unique measurements of 117mm and 86mm centres (PZ) and now form part of the Yale group of companies.
Mantis 1 multipoint locks are available 3 different variants: 3 hooks and 2 deadbolts, 3 hooks and 2 deadbolts with 2 rollers and a 4 roller version. There is also a passive lock version. Historically, Mantis 1 locks have been produced with hooks and deadbolts in different locations. Unfortunately, those locks are no longer available, so some work will be required to reposition keeps and locking positions.
The variant without rollers was often used on timber and composite doors, whereas the version with rollers was used on UPVC doors. You may come across Mantis 1 locks with a cover plate fitted, to match the, often composite, door installation. That cover plate is either 24mm or 44mm wide and locks with this feature are no longer available. However it is possible to re-use this cover plate on your replacement lock. A linkage plate runs behind the cover plate, so it is possible to swap the 16mm faceplate to the older 24mm or 44mm faceplate without much trouble. The linkage will likely be longer than your existing installation, so will need trimming before fitting.
Identifying a Millenco Mantis 1 multipoint door lock is straightforward as it is the only lock on the market with a double spindle, 117mm and 86mm centres. This is the best way to ensure that you have the correct lock as early versions of these locks had no brand stamped on the faceplate.
Millenco Mantis 1 gearboxes are only available in one configuration and backset. The configuration is double spindle for lift lever or double spindle nightlatch operation. The only backset available is 35mm.
Mantis 1 gearboxes are some of the largest on the market, measuring 260mm high by 53mm wide. They feature a central hook bolt that is 45mm high and a latch which measures 23mm high and projects 11mm.
Even though the faceplate can be unscrewed, a Mantis 1 gearbox cannot be swapped with a replacement as it is connected to the linkage rail that runs behind the faceplate. However, repair parts are now available to repair existing gearboxes. Please refer to our multipoint lock gearbox category for details.
Millenco hooks are comprised of a hook that moves upwards and a deadbolt, immediately below it. Hook cases measure 140mm by 48mm and the deadbolts throw 20mm into their keeps.
