Hi guys. Thanks for tuning in. My name's Darrel, I'm head of the tech team here at LocksOnline.co.uk, and today we've got in front of us is the Yale/Union L2224 Euro Profile Mortise Sash Lock.
It's a narrow style sash lock, and it's designed for applications where, to be honest with you, you haven't got much meat in the door style in which to fit a lock that's a lot deeper. But also there was a time when this particular type of lock was used in metal doors or aluminium doors for domestic properties and it has a few distinct features.
And one of the distinct features of this particular type of lock is that the actual face width there which is quite an unusual measurement is only 22 millimetres, and you'll find that a lot of aluminium doors, I mean there was a manufacturer, I'm not suggesting that John Carr used this particular type of lock, but there was a rage of them using this narrow style with the euro profile handle.
So this is, it's now badged under the Yale brand even though it's got Union written on here, it is actually a Union lock but you can now buy it as a Yale, it's exactly the same lock it's just that it's all owned now by ASSA ABLOY. Some of the distinct features of this particular type of lock, however, is that by using the Euro profile you can obviously throw the bolt out, but let's assume that you're on the outside and you wanted to come in. You can put the key in turn it, and it would throw the bolt back like you would expect, but if you continue to keep turning it, then it will actually bring the latch in as well. So you can actually operate the latch via the cylinder, as well as the handle. You have the ability to put a handle in there as well if you wanted to do so.
But sometimes this particular type of lock was used to latch locked, and then when you wanted to secure it you'd throw the key and deadbolt it. Therefore there was never any need to have a handle on the outside. So that's one of the top tips there for you to be aware of.
You can also change the handing, so at this moment in time depending on your handing that obviously latches in that direction, but you can turn it from undoing a bolt at the back and turning it around so that it can be latched from the opposite direction. Now, this is more of a replacement lock for those type of aluminium doors, but still can be used in wooden doors. There's no reason it can't be used in wooden doors.
Some of the distinct features, as you can probably see there, I don't know if you can zoom in there for us Lee, but they've got little roller cams in the bolt. And that's designed to stop anybody trying to hacksaw through. Then, if they hit those roller cams it's going to make the cams freely rotate, meaning the hacksaw is going to sit there awhile if somebody's trying to hacksaw through. So there's another bit of security in that respect.
To give you some sort of measurements, if I go on and carry on with a few more measurements for you, okay? Is . . . you've got the PZ measurement, which is the distance from there to the centre of the keyhole. Now it's important that it's the centre of the keyhole guys and not the actual gam cylinder, so it's the centre of the keyhole. From there to there is 47.5 millimetres. So that's that measurement there. The backset, which is the distance from the faceplate to the centre where you put your key in, is 31 millimetres. The case height, that's this here, is 108 millimetres. The fore-end height from there to there is 153 millimetres, and like I said the fore-end width here is 22 millimetres.
So, still used today, but more of a replacement lock for those type of aluminium doors that were around you know, maybe 10, 15, 20 years ago. Comes as standard with a keep as well, that comes as [found enough 00:04:05].
It doesn't come with fixings, you would be expected to use the existing fixings, or because it's designed for either wood or aluminium you would machine your fixings to suit your particular type of application. And as you can see on the inside of the plate there you can see there's the holes there for the fixings. Okay? And obviously . . .
