Hi, guys. My name's Darrel and I'm head of the tech team here at LocksOnline.co.uk. Thanks for taking some time to tune and have a look at all of our product review videos. Today we're talking about aluminium shop-type commercially graded doors and the type of cylinder that you might see or might expect to see on the inside of the lock on the door. Now these particular type of aluminium doors I'm referring to are the type that you may see on shop fronts or you may see on office buildings, on commercial-graded flats where you've got a communal access and you need to go up through a block of flats. You might see them on other forms of commercial buildings or banks or similar.


Now normally you'd have a key on both sides and when you want to lock it, you put the key in, throw the bolt over, and it would be locked, but in some applications, you may need to be able to use a thumb turn on the inside, so you don't need a key in which to unlock it or to get out. And if that's the particular case, this is the type of product that you would probably be looking at wanting to get. That is what we call there a screw-in cylinder. The idea is the thumb turn is there where you would normally have a keyhole, and what they've done, in effect, is they've taken out the key and the cylinder and they've put a thumb turn in its place, as you can see there.


Now, these work with Viro, there's Adamsrite, there are other manufacturers out there who make locking systems and locks for aluminium shop-type commercially graded doors, and this is the type of screw-in cylinder that you would expect to see in those type of doors. So from the outside you'd see this round there and it's got a little bit of this crown there as well, this rosette to finish the job off a little bit. This rosette also has other unique functions as well. It stops to try to get a direct attack against the actual cylinder itself and try to force it out, and by clamping on that, it actually means that it's harder to actually get at the cylinder and this will rotate slightly.


To get these out what you'll find is that on the front of the lock is a faceplate. You need to take the faceplate off and inside there you'll see a grub screw, and it's that grub screw that holds itself into that groove that sits there. I don't know if you can zoom in there. Perhaps if I do the back you can see the groove there a little bit better.


So you need to undo that, and then once you've done that out a little bit, be mindful when you're taking that out, from past experiences, you don't want to take it out all the way because it has a tendency to drop down into the door, like sometimes you might be unfortunate at the bottom of the door is sealed and you've lost the screw forever. So only take it out a little bit, and until you can start to turn this, and the way that you need to turn it is you need to get something on there and just give it a little turn. By right it should be loose. It shouldn't be tight at all. If it is tight to get turning, what you want to do is slacken off the screws to the actual lock itself, so the whole lock sits quite loose in the door, and it turn out with no problem at all. Last thing you want to do is to cross-thread it or strip the threads, etc.


So that's what it's designed to do. It's basically designed to be able to operate that type of lock that has a dead lock or a latching function, etc. on a commercially graded aluminium door, and the idea is that you can operate it without the use of a key on the inside. So, that's Aset's version. We do have other manufacturers on our website. We've got our own range, we've got Union has a range, etc. Cisa has a range, etc. There's quite a myriad of different manufacturers creating a screw-in cylinder. All of the cams on the back of them are pretty universal these days, unless, that is, your dual lock is going back to the 1980s where there were actually three different types of variation. But now it's pretty universal and is pretty standard.


So I'm hoping that will give you a bit more information as to what this is and what it's designed to do, and perhaps this is what you're actually looking for in solving a solution, solving a problem, however, that you may have. But if you need a bit more information or you want a bit more advice, by all means, pop us over an email, use the live chat on our website, just pick up the phone and give me a call personally, or any of the guys in the team. We'd love to hear from you and, more importantly, 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 we hope to catch up with you real soon. Bye-bye now.
