Hi, guys. My name is Darrel and I am 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.
And today we are talking about the Willenhall M3 Five Lever narrow style sash lock. That's designed to go primarily on doors where the locking style, that's the part of the timber where the lock goes into, the locking style is quite narrow. And, of course, the beauty is that this particular type of lock is that the case depth there is only two inches, okay. So, it's really great for French doors where you're opening outward, etc. or where you've got sets of doors, etc. Again, as I've mentioned, where the locking style is quite narrow,
It's five lever. So it's the minimum security that you would expect these days on final exit doors. It's not British standard. It can't be British standard because basically there is not enough bolt throw these days in this size of lock case to allow the bolt to come out to comply with the British standard. So that is quite well worth knowing about. It's only available in a brass finish, as you can see.
So let's get a few measurements and it will hopefully help you to determine as to whether this is the actual lock that you need for your door. So the actual size of the actual case depth there, as you can see, is 50mm. The case height is 105mm there. The backset, which is the distance from the leading edge to the centre of where you put the key into, is only 32, 33mm. The PZ measurement, and that's the measurement from the keyhole to the centre of the follower, that measurement is 55, 56mm. The actual fore end width is 25mm and the fore end height there is just a smidgen over 152mm.
It comes as standard with a full box strike, as you can see there. Therefore, that's obviously going to be a lot better than just having a plate. You've got a little bit more security in regards to box strike. And, it also comes as standard with two keys. Now, we can key these alike for you. So if you wanted a group of these all on the same key, we can do that. We can key them alike for you. That's not a problem at all.
So there you go, guys. It's the Willenhall lock. It's the M3. It's the five lever sash lock available now on LocksOnline.co.uk.
