GU Ferco 635 Multipoint Door Lock

GU Ferco 635 is the updated version of the old Ferco 635. Click here for the old Ferco 635. This updated version is made by GU which is Ferco’s parent company. The updated version has the exact same roller positions as the old version. It has a 35mm backset and 70mm centres. The new version features an new quick reversible latch. Simple remove the Philips head screw holding in the latch, turn the latch around and refit the screw.

There is only one major difference between the updated version and the old version. The position of the latch on the updated version is located 5mm higher compared to the old version. This shouldn’t be an issue in most doors, as the frame keep has a large strike area. The worst case scenario is re-positioning the frame keep up a small bit to suit the new latch position. See pictures for comparisons between the updated and old versions.

Identifying the Door Lock

Look along the face plate of your door lock (where the locking points are) until you locate the manufacturers name or logo. On Ferco 6.35 multipoint door locks you will see “Ferco 6.35” stamped on the face plate. This door lock has two roller locks and one latch.

Important note on GU Ferco 635 Door Lock Size

The overall length of the lock is 2050mm. It is this length to suit different door heights.  In most cases you will need to cut the face plate to suit the size of your door. It will usually be the top of the lock face plate that will need to be cut. The easiest way to check this is when you have the old door lock removed, hold the old lock and new lock beside each other. Mark the overall length from the old lock and cut with a hacksaw.

Cutting the faceplate to length will have absolutely no impact on the function of the lock
