These are Imperial's old style horizontal sash locks, with the large 127mm backset seen on many old style doors typically utilising door knobs instead of lever style handles. Then you also have the backset on the keyhole which is 57mm as you'd expect.
Another well thought out aspect of these sash locks is that they also have holes either side of the follower which are designed to accept bolt-through furniture fittings, so if you have a door knob on either side of the door, which clamp together via bolts through the door, this lock will cater for it. Good call, Imperial!
The steel case is finished with an epoxy powder coating, with brass internals, including the follower and both the latch and deadbolt, for that perfectly smooth operation you would expect from Imperial Locks. What's more, the latch is reversible, so which ever way your door opens, this latch can do the job without having to choose a different model for left or right handing!
The strike / keep plates and faceplates are available in either a stainless steel or brass finish, allowing you to match them up to your existing door furniture.

Hi, guys. My name is Darrel and I'm head of the tech team here at Locks Online. Thanks for taking some time to tune in and have a quick look at one of our product review videos. Now we're putting these short little videos together to be able to give you, our customers, the opportunity to see the products that we have to offer in hopefully a little bit more detail than you may get from just an image or a bit of descriptive text.
Today I want to show you a horizontal lock that we have on our website. It's manufactured by the company Imperial, which is a British based company, and this particular lock is what we call in the industry a horizontal lock. In other words, it's designed to fit the majority of the older style where you'd have a knob on this particular side here, and then you have the keyhole a little bit further. Some of the unique, distinct settings in regards to this is that the actual latch always sits at the bottom on this particular type, and the bolt then sits at the top, as you can see here.
Now this particular version, as you can see here via the keep, is the satin nickel, or the satin silver finish there. But it's also available in a satin brass finish as well. So if you're planning on wanting to use knobs on your door or a spring loaded knob, etc., and have an escutcheon then, this is the traditional style that you may probably see a lot of in the UK in respects to that. Now you may also find as well that there's a lot of this particular type of lock were fitted way before decimalisation, so just a few top tips. If you've got a lock that's really, really old, the chances are that the measurements may be slightly out, but it'll be the nearest that you'll be able to get these days.
So one of the advantages with this one as well, it is actually a five lever lock, which means that it can be used on external doors, and it'd be worth checking with your insurance, but normally five lever is about the least now, or the minimum that your insurance company will accept for an external rated door. Mostly it's British standard. This particular lock is just five lever, so you're 90% there, so to speak.
So whilst I have it in my hand, let's get a few measurements for you and therefore then, give you an opportunity to measure up against your particular door to see whether or not this is the lock for you. So the overall length of this particular lock is 152mm from one end to the other. The backset measurement to the follower, this is what we call a follower, this particular part here takes an 8mm spindle, that follower distance there to the centre there is around about 127, 128mm. And then the backset to the keyhole also, if I just measure that from there, you're looking there around about 57mm there.
The case height is 80 . . . I'm going to go 82mm, and the fore end width there, if I can just get that measurement on there, the fore end length is 153mm, and the fore end width there, by all means, is about 25mm. And as you can see there, it's showing the five lever security measurement on there and it's also seized up. And obviously, nice to see it's made in England. It's really, really great.
Now also, it comes with a keep here, a full body keep as well, and it also comes as well with some fixing screws. So you've got everything there that is needed. And another point I want to mention to you as well is, as you can see here, and it has these holes on either side of the follower. This is to allow you to use bolt through furniture, and the general centres there are around abut 38mm. There's a degree of tolerance on either side.
