This can be measured from the edge of the faceplate to the centre of the keyhole, alternatively GU do print '30' and '35' on their gearboxes to relate to each backset size. The PZ centre's for this model is an industry standard 92mm; this as well can be measured at home simply by checking the distance between the centres of the keyhole to the centre of the follower.

GU are one of the industry leaders in manufacturing and producing UPVC products, this model is one of their pre 2008 models of Multi point gearbox.

It is often more cost effective to replace the gearbox itself in a multipoint lock, they are usually one of the first parts to fail due to the amount of mechanical work they are required to carry out.

The pre 2008 GU multipoint gearbox is available with a reversible latch that can easily be turned to face the other direction.

Hi, guys. My name is Darrel and I'm head of the tech team here at LocksoOline.co.uk. Thanks for taking the time to tune in and have a look at one of our product review videos.


The products that we have here today are the GU gear boxes that replace the multipoint locks on UPVC doors pre-2008. So here they are here in its standard form. Guys, here is just the gear box on its own. You don't necessarily these days have to change the whole multipoint mechanism with all of the roller cams and the bolts, etc. What you can do is just change the gear box. Ninety per cent of the time, the reason why you would want to change one of these is that the lift-up mechanism starts to break down because the door is being forced, etc. and you are finding it difficult. What normally happens is this little cam, just inside, I don't know if you can zoom in here, this is the follower. This particular part starts to break away. And consequently that's the reason why the gear boxes have premature failure on them.


Now, pre-2008 they called these particular types of gear boxes G3 type, the Europa range of gear boxes, and they come in two different backset sizes. This one I have here is the 35mm backset. But they also do a 30mm backset, which is there. So it's in a little bit further. Those are identifiable if you were to take your lock out of the door, you would see stamped on them, 3592 or 3092. So it would be well worth having a look to see which backset you've got.


Also, another critical measurement as well with these is what we call in the trade the PZ measurement. That's the distance from the centre of the cylinder to the centre of the actual follower there, and that is traditionally now 92 mm. And on these, it's 92mm. Now you can get these particular gear boxes off and this one here, it comes with a set of torque screws and what you can effectively do is to take these off and that can allow you then to replace the gear box, no problem at all. And then you would need a torque driver in which to do that. I don't know if you can zoom in on that for us to give you guys some sort of idea as to what they are.


So the operation is quite simple: it's basically you lift the handle up and you would turn the key in to the door. By lifting the handle up it would throw the bolt over, the rest of the combination would come off here, the multipoint to the top and the bottom, that would engage as per normal and then you would turn the key and lock the handle off. Now they did do a range of split follower versions; they are no longer available. Now it's only the standard follower that you see here. That standard follower, I've got a gauge here. I'll just sort of give you guys some sort of idea as to the measurement, and that is the standard 8mm follower there.


So, there you go guys, so the backset is measured from the leading edge to the centre there and they're available in 30 and 35. And the PZ measurement is from there to there, and that's the standard 92. If you wanted to reverse the latch, you just basically turn it around like that before you screw it into the actual part of the multipoint that operates the rest of the mechanism.


So there you go, guys. If there is any information that you need on these or there is something that I haven't mentioned that you may want to say, "Oh, I'm not quite sure," or, "I want to know a bit more," by all means, use our live chat on our website. It's totally free. And use the phone, you can phone us up and have a chat or pop us over an email. Either way, we'd love to see you as a customer. So from me, Darrel, and all of us here at the LocksOnline team, take care and catch up with you real soon. Bye-bye now.
