Hi, guys, my name is Darrel. I'm head of the tech team here at LocksOnline.co.uk. Thanks for taking the time to tune in to have a look at one of our product review videos. The products that we're going to look at today is the new rage. It's the post-2008 rage of GU gear boxes.
Now we've got a follow multi-part lock here to the side of us, but I'm using that really to give you guys some sort of ideas and some markers as to what you should be looking at on the face plate of this lock to make sure that you're choosing the right gear box.
Now there was a major shift with GU in regards to design and development of gear boxes and a lot of things happened in the year 2008. So, if your door is pre-2008, the chances are you are not going to have this gear box. We do do a range of the older gear boxes. Nut if it's 2008 onwards then that chances are that this is the type of gear box that maybe in your composite or UPVC door.
Now on the actual gear box-sorry on the actual lock itself, now I've got this one whereas you've got different types of cams and mushroom cams, etc., don't think that you need to have these in the exact places, this is just one of the locks. The chances are you may have different types of locking solutions. What we're interested in today is in the gear box, this part here, the centre piece here.
All you need to be looking at-I don't know if you can zoom in enough for us there, Lee. But if you notice there you've got the symbol that says GU. If I zoom in there. So if you got GU and your door is 2008 onwards, then the chances are that this range of gear boxes will fit on your particular type of multi-point lock.
Now, the other distinct differences with this as well is how you are actually changing the handing on these locks. I'm just trying to hold it up there a little bit more. The handing on these...sorry, they've actually changed the handing of these particular types of gear boxes. They're a little bit different than norm. Some of them use screws on the front; some of them use the screw on the back etc.
But these here you would use a flat-bladed screwdriver and you would push it in there. This then releases the actual latch, allows you to tune it, push it back in, and click it in. So a flat-bladed screwdriver into that slot there and that's how you would change the handing to turn this latch around. It's quite distinct on this particular range of multi-point locks.
Now in standard, they come with a 28-millimeter backset. That's the distance-whoops, that one is upside down. That's the distance from the leading edge to the centre of the keyhole, okay? That's the backset. This is the 28-millimetre version, and it's quite different and unique in as much as it has this black face plate and so forth.
All right, so the PZ end measurements, that's the distance from there to the distance to the centre of the keyhole, that's 92, and that universal throughout them all. So it comes in 28 millimetre; it comes in 35 millimetre; it also comes in a 40 millimetre back set which we're now getting into composite doors and wooden doors. And it also comes in as well in this whopping 45-millimetre backset as well. And again the different type of locking mechanisms could be different all the more.
If your lock is broken or failing in any way, 90% of the time, not always, but 95% of the time it's the gear box that's failing. So you don't necessarily have to change the complete multi-point, all you need to do is change the gear box. And that's why now gear boxes are become more popular as opposed to whole mechanism.
Another distinctive advantage with this particular type of multi-point as well is that on the 35-millimetre version it does come with a split follower. Now this one doesn't have a split follower, and you can notice that it doesn't because it's the standard silver finish on the actual follower there. But only split follow version, which this particular multi point is, you'll notice that the actual follower there is brass.
Right. Now what that spit follower allows you to do is to use what we call in the industry a split spindle and allows you to have different functionality on the inside and the outside of the lock. You would have that sitting on there like that and then you'd have that fitted in there like that and it allows you to have a latch operation from outside, so it can work like a Yale lock whilst at the same time on the inside, you just drop the handle and out you go.
So that's the purpose of having a split follower. It may be that yours may have that and when you take your lock out of the door , you've taken the handles off, you've taken the lock out of the door, if it's got this sort of type of follower, it might not necessarily be strong welded. But that type of follower system where they split into two, then you know it's the split follower version and you know it's only available to the 35-millimetre backset lock kits.
Now when it comes to actually taking these off, they use a standard torque 20 screw heads and you just basically unscrew those off the back of the plate and that allows you to screw the new one back in and it's really as simple as that. So a lot of both the myths and mysteries of multi-point locks is starting to be moved to one side because it's now getting a lot easier just to change the gear box and your UPVC door is working well.
So that's the range of if it's the new G.U range of gear boxes post-2008. So if your door is 2008 onwards and it's got GU stamped on it chances are this is the gear box for you.
