Multipoint & UPVC

This Winkhaus Trulock multipoint door lock features 2 Hooks, 1 Deadbolt & 1 Latch.

The Winkhaus Trulock is a multi-point locking system suited for use with timber and composite doors in the social housing and new build markets. It featuring a central latch and deadbolt and2 or more hook locking points. Trulock multipoint locks are available with lift lever operation, split spindle or key wind.

Winkhaus Trulocks are characterised by their central latch and deadbolt. They will also feature either 2 or 4 hooks as the additional locking points. Trulocks always feature handed hook locking points, which cannot be reversed on site.

It is also worth noting that Winkhaus Trulocks feature the same gearbox as a Cobra, but with slightly different hooks. Cobra locks are non handed, whereas Trulocks are handed.

The quickest way to identify the product, before removing it from the door, is to check the faceplate. You’ll spot a Winkhaus logo and, often, a Secured by Design logo. The Trulock version will be identified by the central deadbolt and handed hooks.

Usefully, all Winkhaus locks feature the same routing details. Therefore, if you wish to change the locking operation, or upgrade to automatic locking, its a straightforward process. New keeps and handles may be required.

All Winkhaus gearboxes, apart from the AV4 measure 185mm high x backset + 15mm, making them the smallest gearboxes on the market. They measure 64mm between the latch and deadbolt and 63mm from the spindle to the top of the gearbox. They also feature a groove above the spindle to aid in the fitment of handles with a screw above the lever.

Winkhaus gearboxes are attached to the faceplate with a set of rivets. These can be easily removed and replaced for gearbox swaps but makes Winkhaus relatively unique (and therefore easier to identify) in the market. Please refer to our guide and video on how to replace a Winkhaus gearbox for full details.

Winkhaus Trulock gearboxes always feature a latch and deadbolt in the gearbox. They are available in lift lever, split spindle and key wind operation and are interchangeable with Cobra gearboxes. These are easily identifiable by the sticker on the side of the gearbox. If the writing is blue, This is lift lever, if its green, then the lock is split spindle, whereas red means key wind. We often will only stock the green, split spindle locks, where both a lift lever and split spindle version are available. This is because the split spindle can be used as a lever operated lock by inserting a solid spindle all the way through the follower. There’s also no price difference between the locks, so the added versatility of the split spindle lock makes it a suitable replacement for a larger range of locks.

Please note that you may have encountered a really old Winkhaus gearbox that is attached to the faceplate with screws, with a passivated yellow finish. The sticker on the side (red = key wind and blue = lift lever) will denote the operation of the lock. These locks were handed and are no longer available.

Trulock features a special design tensile steel handed hook with a 4.5mm chamfer allows a high degree of fitting tolerance for door installation. In addition the hook shape provides low operating forces and helps doors achieve a higher level of weather performance.
