Hi guys, my name's Darrel. I'm 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.
The products that we're looking at today is a range of Yale gear boxes. It's part of their new range of multi-point locks. They're available now on the market. What I've done is, to my side here, is I've actually got a full multi-point lock to give you some sort of idea as to some markers etc., to help you identify as to whether or not these gear boxes is what you need to change.
Now one other thing is, is that a lot of the failures in multi-point locks as time goes on is not necessarily the locking function. It's more to do with actual gear boxes, the part in the centre that's doing all the work etc. So that's one of the key indicators that you need to be aware of.
So if you've got your lock, if it looks anything like this, what you'll find is here, is you'll find Yale written just below the pop bolt there, you'll see Yale, and then you see YS170 stamped on.
I don't know if you can zoom in enough there, for us. I don't know if you can actually get that marker there. One thing you'll also notice as well is it does have this whole back facility, as well. This is in the locked position, but if this was actually pushed in, you could then push that up there, and you could hold the latch back if you wanted to. So that's one of the key features, as well.
Now, it's the gear box that we're talking about, not necessarily the complete locking mechanism. You'll see that this one, just while we're talking about it, you'll see it's got a wider one. This is the 45-millimetre backset that's additionally used on composite doors. And we have the gear box here.
So if I put that down a second, what you'll also notice as well, I don't know if you can actually zoom in on here, is that traditionally you would have pop bolts on the top. On the bottom as well. So that's another little indicator for you.
But, as I've said, it's the gear boxes that we're talking about today. And this is the actual gear box here. Now what you'll find is is that, as standard, the backset here as standard for a UPVC door is 35 millimetres. Okay? And the PZ end measurement, that's the distance from the centre to the actual centre of the follower there, all right, is 92. That's pretty standard in these particular locks.
Now if you're doing the wooden lock, if it's on a composite door or a wooden door, you'd then have the backset, you'd have the backset there at 45 millimetres. But, again, these are standard 92 millimetres.
Now another feature that these locks have, as well, is that they can utilise what they call a split spindle. In other words, this is what a split spindle looks like. And it may be that if you take your lock apart, and you see this type of split spindle here in the centre, the reason for this is that it has different functionality from the outside compared to that on the inside. The purpose behind that is, is that if you just wanted to use a latch so when you close the door, it would just latch locked, then fine. But from the inside you're going to open it from the handle. So that's the purpose behind all of that.
Now for changing the handing on these, again, it's pretty standard. All you need to do is undo the screw there, undo that, take the turn lock right, and pop that back in. Now one of the key markers that you need to be aware with these, as well, is that there's also a range of Yale multi-point locks. All have Yale stamped on the front, but the actual latch is below. It's here, and the pop-up is at the top. Don't be confused with that one, with this one. We have the video on that one as well on our website. But they are different so you need to be aware of that.
The key indicator here is the latch sits in the traditional set at the top here, and hub bolt at the bottom. All right? So that's another key LocksOnline top tip that you need to be aware of.
So there you go, guys. I think I've said all I need to say. At least now, you can see it in the flesh. If you'd now taken your lock off the door, you've seen all these little markers, that Yale, etc. The chances are that this is the gear box that you need to change. You don't need to change it all, and so we could save you a couple of quid on that.
So from me, Darrel, I hope I managed to get you through everything. If there's something that I haven't mentioned and you need to know, pop on the phone, use the live chat. Either way, we'd love to hear from you. And, more importantly, we'd love to see you as a customer. So from me, Darrel, take care and catch up with you real soon. Bye-bye now.
