Offers flexible traffic control and an excellent level of security (though not the maximum security of the MS®Deadbolts), and is often used in conjunction with 7100 Series Electric Strikes to provide remote access control. The auxiliary bolt feature deadlocks the latch when the door is closed against the strike.
Reversible latchbolt withdrawn from either side by key or turn using any standard screw in cylinder or thumb turn (with cam) or 4590 paddle handle (with 4580 cam plug). Also range of lever handles available to suit. To operate hold back facility push in bolt and secure by reverse turn of key
Maximum operational door gap is 5mm. Operates using Mortice Cylinder, Thumbturn (both with MS®cam) or 4591 Paddle Handle (with 4580 cam plug). The latch is interchangeable without stile modification with the MS®1850S Deadlock. To operate "Bolt Holdback" feature, push in bolt and secure by reverse turn of the key. Latchbolt reversible; supplied non-handed unless specified. When used in emergency exit applications with a 4591 Paddle Handle, the assembly must use the 8460 Ramped Jaw Strike in order to conform to BS EN 179+A1: 2001.
Latch is automatically deadlocked when door is in closed position.
All faceplates and strike plates must be ordered seperately
Notes :Backset measurements includes faceplate
Hi guys, my name is Darrel. I'm head of the tech team here at LocksOnline.co.uk.
Today we're going to have a look at the Adams Rite, the 4170 Mortise Night Latch that's designed for aluminium doors. So, here it is here. I think I want to zoom in on that for us there Lee. You'll find these in aluminium shop- front doors, typically, any aluminium or commercially graded aluminium door. You may find them, I mean, a classic place where you may find these is in petrol station forecourt doors where they've got a strike-release working on this particular type of locking solution.
Now I wanted to go through the bits and pieces with these because if you're not familiar with them, let's go through exactly what we do have and how it's actually fitted into the door and what type of cylinders and all they use. So if we work our way from the top, we've got this type of fixing here, I don't know if you can zoom in on that, and this allows you to make adjustable fixings within the aluminium frame. Now some doors don't accept this particular type and you have to use a bridging system, but this could, if you wanted to, be taken off if you don't want to use this particular set up.
It takes a screw-in cylinder here, what we call in the industry a screw-in cylinder. I don't know if you can zoom into that, but that there is typically a screw in cylinder. So it's got a thread that sits on the side of the cylinder. You'll also notice on the cylinder, I don't know if you can zoom in that far, Lee, there. But you'll see that there's a little dip in the actual side of the cylinder.
If we go over to the lock here, and if I was to position it like that, you may just see inside there a little bolt and that little knurl is meant to sit so when you screw the cylinder in you can tighten up that nut there, that little screw there, and that would keep the cylinder from stopping it from turning, etc. So what you'll find is sometimes, you'll have a turn on the inside, or it could be a cylinder, and then have a cylinder on the outside.
Now the way that the latch works as standard is this is a dead-locking facility here, but when the door is in the closed position this gets pressed in and this then in the turn dead locks this particular latch at the top here. When it's open it is obviously is free access there. One thing that people are not familiar with, on these particular locks, you can actually hold the latch back and there's a little mechanism built inside. I don't know if again it's . . . probably at the back it would be easier to see them. There's little nodules here. These nodules that when you push this back you can use the cylinder to push these forward and this actually holds then, the latch, in the open position. So the door now can become free access.
Again ideal for forecourts, so you could have free access in the day and then when it gets nighttime you can put that over and then it goes on to the access control solution.
Now as standard they come in two different size backsets, and it's important for you that when you're measuring these you don't measure them with the faceplate. It is actually the lock. You'll see normally you'll have a faceplate that sits over this, and that sit then – it can be either curved or anything, but you don't measure the faceplate, the aluminium faceplate when it comes to measuring the backsets.
Now this particular one here is a 24 millimetre and it's measured from the centre of the actual keyway to the leading edge here. This is 24, they do an option as well 22. And there are other options as well, available. But to give you some sort of idea for measurements, the backset will always be different depending on the lock that you choose, but the fore-end plate width and so forth will always be the same. So let's get the tape measure and get a couple measurements off the overall lock.
So if you're thinking you need to replace this particular lock at least you'll have some sort of idea as to whether or not this is the lock that you need.
So with my tape measure I'm going to measure the fore-end width and that is 25 millimetres. I'm going to measure the fore-end height and that's 175 millimetres. Now obviously the case depth and so forth is going to change depending on the backset, but this one here which is the 24 millimetres version, the overall depth of that one is just 36 millimetres. So it's just over the 35. And the width here, the case width here is, that's going to be 22, about 22 millimetres. So there you go.
That's the Adams Rite 4170, it's used in aluminium doors, commercially graded aluminium doors as a latching solution should you want a little bit of security, and is used quite extensively in the access control industry.
May I take this opportunity to thank you for having some time to watch this video. I hope this has allowed you to make a considered opinion as to whether this lock is suitable for your application. But in the mean time if you need anymore help feel free to give us a call or pop online or pop me an e-mail at Darrell@LocksOnline.co.uk.
I'm sure that we could – I'm sorry. I'm sure I could answer any questions that you may have. In the meantime take care and it's all the best from me. Cheerio now. Bye-bye.
