This part is discontinued and is no longer available.
However, part: FULCASE is a potential alternative. As this lock is discontinued, we'd recommend a replacement gearbox. If a full, replacement lock is required, a VERSA V-MPL repair lock can be used. Some adjustments will be required but it is supplied with keeps for any new locking positions.
This lock was the original multipoint to feature a hook and deadbolt combination but is now discontinued. The gearbox only is still available.
Fullex SL16 multipoint door locks have been fitted to doors for decades and were widely specified in both private and social housing. They feature a completely unique PZ centre measurement of 68mm. No other current full length multipoint door lock has this PZ measurement.
SL16 locks are available in various different configurations and faceplate sizes. All locks in the range feature a central latch and deadbolt with 2 additional deadbolts, located equidistant from the spindle. The measurement is 650mm from the spindle to the top deadbolt and 650mm from the spindle to the bottom deadbolt. Certain variations of this lock feature an additional hook lock between the main gearbox and the top deadbolt. That is located 345mm from the spindle.
Identifying a SL16 multipoint door lock is simple. Although older versions of this lock do not have the Fullex brand stamped on the faceplate, the centres on the gearbox are an absolute giveaway. If the centres are 68mm, double check that the lock isn't one of the original type A-G locks (you can find more details on these in our gearbox category).
Faceplates are available in 16mm or 20mm variants and are manufactured from austenitic stainless steel.
SL16 handles require handles with 68mm centres (the distance from the centre of the euro cut out to the spindle). You may find that your handles are standard lever lever or lever pad versions or they may feature a snib that allows the latch to be held back. Lever lever handles with a hold back snib are still available, but lever moveable pad versions with a snib are not.
Fullex SL16 gearboxes are available in 35mm, 45mm and 55mm backsets and all feature a split spindle to allow them to be used as a lift lever or split spindle nightlatch function.
All SL16 gearboxes feature a 68mm centres (PZ) measurement. This is only found on Fullex locks (the FULCCA also has this measurement). The overall case height is 194mm. The case width is the backset + 15mm. The latch is 27mm high, the deadbolt is 32mm high and the distance between the bottom of the latch and the top of the deadbolt is 65mm.
SL16 gearboxes come with fixing tabs at the top and the bottom of the gearbox. These measure 15mm wide by 9mm deep. The lugs are 11mm wide. The case attaches to the faceplate with screws at the top and bottom which measure 206mm apart.
SL16 locks do not feature hooks in the traditional way that some multipoint locks do. Instead, some versions use a single, additional hook, located between the gearbox and the top deadbolt to provide additional security.
Fullex SL16 deadbolts are tapered to offer both security and compression, so that the door is pulled tight to the frame.
These deadbolts throw 20mm into their keeps when the lock is engaged for extra security.
