This is a Fullex Old-Style replacement gearbox, this was a very popular style around in the early days of multipoint locking, and these gearboxes can wear out over time. So rather than replacing the whole multipoint lock, in most cases you can simply replace the gearbox where there's no visible problem with the rest of the locking soltuion.
A distinct marker of an original installation of these would be the 25mm faceplate. Nowadays we see 16mm faceplates on multipoint locks mostly, with some 20mm's being seen on wooden and composite doors, but for uPVC this is now 16mm that we recognise as 'standard'. But back then, these were fitted on 25mm wide rails.
The PZ is 68mm too, as opposed to the usual of 92mm these days, and with a 37mm backset these are very distinct.
Hi, guys. My name is Darrel and I am head of the tech team here at LocksOnline.co.uk. Thanks for taking some time to tune in and have a look at one of our product review videos.
Today we are looking at the gear box for an old Fullex type of multipoint lock that you may find on UPVC doors. This was quite prevalent around in the mid-‘80s, in the early ‘80s. Not necessarily made anymore, the actual locks in the cases and so forth and the actual plates and so forth on the front are obsolete. So you can't get them. But we can still get the gear box, and this is the part that sits in the centre. This is the part that's doing all the work, when you lift the handle to lock it and when you want to turn the key, this is the part that's doing all the work and over a period of time people don't necessarily maintain the locks as well as what they may should be. They might get a bit corroded and they get a bit stiff or they are gone out of alignment and a lot of wear and tear ends up being abused onto these particular type of gear boxes.
Now I have give you some sort of distinguishing marks, if you have got this particular type of gear box with this particular type of multipoint lock. Back in the ‘80s the actual face plate, the leading face plate would have been white and also the actual width of that would have been 25mm. Today's industry standard is 16mm, so it's quite chunky. It's very, very wide.
Also, that sits above the latch as well, you may have seen a little bit of a dome that would have sat in there and it would sit out on the face plate. It was a bit of a latch softener that was used for when you close the door, which softened the latching action a little bit. So that's quite distinctive. And another distinctive marker is, I mean, look at the thickness and the bulk of this particular type of lock. I mean people making locks these days, you now have solid pieces of construction. To give you some sort of idea here, the width of that there is about 20mm. You are not going to see that sort of thickness and stature in modern day locks anymore.
Now, it also has some sort of distinct measurements as well. The PZ measured from the centre of the spindle there to the centre of the keyhole was 68mm. And when you measure the centre, it's from where you put your key in and not the actual cylinder itself. It's well worth you having a look at that. Also as well is the backset as well, from the faceplate to the centre here, what we call the backset, on this particular lock is 37mm. It's a little bit unique. It's slightly different. Most locks are either 30 or 35mm so it's a little bit out of kilter again in regards to these locking measurements.
We can change the latch function by simply unscrewing the screw there, turn the latch around and that allows you then to have the universal handling that you may need as well. Of course you have got the bolt that throws in the centre. So this is the actual gear box. It's called the Fullex case A gear box and is of course available on our website. Just to give you a little bit more information as well, the actual follower, this is where the spindle goes into, is what we actually call in the industry a split spindle, a split follower, which allows functions from the other side of the door. For example, you might have a key retention on the outside so it will work like a Yale type of lock whereas on the inside you can drop the hammer down and the lock would open. That has this functionality as well if your particular set is using it.
So there you go, guys, there's not really much more I can say about it. But if you need a bit more information or there is something that you need to know a little bit more about, by all means pop us over a call, use the live chat on our website or by all means pop us over an email with a couple of photos of your particular lock in question. I'm sure we'll be able to help you some way or another. So from me, Darrel, many thanks for taking the time to have a look at this video. I hope it's given you a little bit more information. Please come along and say hi to us, more importantly come and be a customer of ours. That would be really appreciated. So from me, Darrel, take care and catch up with you real soon. Bye-bye now. Bye-bye.
