Hi guys. My name is Darrel. I'm head of the tech team here at LocksOnline.co.uk. Thanks for taking some time to look at one of our product review videos and more importantly the product that we are looking at tonight is the 4720 dead latch from Adams Rite.


Now this is the dead latch here. It's designed to work in aluminum doors, in metal doors. You will probably find this particular type of lock in commercially graded doors that are used on commercial buildings, shop fronts if they've got a locking solution. But you may also find them on the petrol station forecourt doors, etc., where you have this latch here that allows an access control solution perhaps that someone could release the door from inside. So this is the type of lock you would normally have.


It does have a hold back feature and as you can see in this moment in time the actual hold back feature is in its hold back state. So I can actually get rid of that by turning around and dropping these or lifting these little pins up inside here. I don't know if you can zoom in there, if you could zoom in there. And you can operate those when you are turning the cylinder in which to unlock the door. If you carry on, you can actually drop those into place and pop the hold back facility, a lot of people don't know about that but these locks do have a hold back facility.


So if I use a screwdriver, I should be able to pry those out of position there and that one out of there and there you go guys. I have now altered that. No problem at all. You can actually reverse hand these. You would strip the case down and turn this around so it can be handed. This little piece at the bottom here is a deadlocking facility and the idea of the deadlocking facility is to dead lock latch when the actual door is the closed position.


Now to get these particular locks out of the door what you will find is there is an aluminum face plate that sits on these and there are different types, of aluminum face plates. So to digress slightly, when you are measuring these locks and you want to know what size because there are different sizes of these available. The measurement is taken from the lock face plate and not the aluminum cover plate that sits on top. That is quite important. There is one there that is quite close, you can get a 22mm and a 24mm and the difference in that face plate can be the difference in you ordering the wrong lock.


The principal of all of these Adams Rite locks no matter which lock you buy from Adams Rite, is that you always measure from the locks face plate and not the face plate that sits on the outside. So that is a top tip for you. Of course, these take what we call in the trade, a screw in cylinder and I have a screw in cylinder here and the idea is that these would actually sit in here and screw in. And if you notice in there and I don't know if you can zoom in there for a second.


There are some grub screws there and it's those grub screws that are accessible from the front of the lock there, as you can see, that allows you to take this cylinder out. So you would need to undo those grub screw. Remember, don't undo it all the way because that grub screw would fall down inside the door and you may not find it again. So undo it until you can get the cylinder and it starts turning and then you can turn the cylinder out.


A top tip for turning the cylinder is to put your key in about half way and use the key to help you undo the cylinder, if it's a bit stiff undo the screws in it a bit on the lock a bit as well that will allow you to move the lock a bit and it should come out quite freely.


So there you go guys. Like I say, they're all available in loads of different sizes. The back set of this particular lock is available on our website, so it will give you an opportunity to see the back set on this one is. This is used a lot as well extensively with the Simplex Unican 3000 range of combination chambers that again you may find on commercial buildings. You may go up to an aluminum door and you have a narrow style combination lock there and you got to punch some black digits. And then there is a little turn underneath, this is the type of lock that will be sitting in the door quite possibly or a slightly different back set version. But this is the basic lock in principle.


So there you go. It's the 4720 deadlock. It's available Adams Rite and of course it's available at LocksOnline. So if this is the type of lock you are looking for, maybe you will be so kind as to buy it from us. We would greatly appreciate it. But if there is something that I haven't mentioned or you need more information, pick up the phone we would love to hear from you. Use our live chat on our website or pop us over an email. Anyway, we would love to see you as a customer. So from me, Darrel, and all of us here at the team, take care, thanks and catch up with you real soon. Bye-bye now.
