    Hi guys, my name is Darrel. I'm head of the tech
    team here at LocksOnline.co.uk, and today
    we're doing product reviews and more importantly we're doing a
    product review of the Union 3K74E.



    Now this is the actual lock here. I wanted to show you
    this because anybody who's in the industry might say,
    well, hold on a minute, that's not the Union, that's
    an actual Chubb.



    And the truth of the matter is it is actually a Chubb lock
    because what has happened is Assa Abloy, who owned
    Union and also owned Chubb and he owned Yale and he owned a
    lot of other companies as well, decided to disband the name Chubb, Chubb locks, and put all of the Chubb locks over
    onto the Union brand. But suffice to say, the build
    quality and the technology in this particular lock is
    still Chubb which I'm really pleased about because, I've got
    to be honest with you, I like this lock. I think it's a solid lock. it's
    strong. It's sturdy. It's weighted. I mean, you could
    throw this at a burglar and it would hurt them. So I do
    like this lock a lot.



    So let's look at a little bit of the detail on it. So you
    can find out a little bit more about what makes a
    British standard lock. So for starters if you zoom in here,
    you'll see that there's a plate that sits around the lever mechanism that
    sits inside, and this plate here is an anti-drill plate. And
    the idea about this plate is to resist attack by
    somebody trying to drill the lock. That's plus number one.



    Plus number two as well, I don't know if you can zoom
    right in for us, Lee, but this is an actual curtain that
    sits in there that stops anybody from manipulating
    the levers inside. So it's called a lever curtain, and the only way that
    that can rotate when you put the key in, it rotates with
    that. This particular version is the sash lock version.
    So, in other words, it will accept the handle as well, and this is
    the spindle here. It's an eight millimeter follower. This will accept
    an eight millimeter spindle. So this would actually
    operate the latch.



    It's Chubb or Union, whichever way you want to call it. It
    has a distinctive roller bolt latch here so you don't
    have to worry about turning the latch around,
    depending on the handling of the door. I, of course, like that. Another
    distinctive advantage with this being a British
    standard lock is that the bolt projection here which is
    a substantial bolt, but its projection is 22 millimeters.



    And in the front there, I don't know if you can actually
    zoom a little bit there again, but you've got two
    little roller bolts that sit in there and the idea there is
    somebody decides to come in here and hacksaw that bolt off and when those
    roller bolts, those roller bolts will spin. The blade will
    just spin round and round. By the time you move the blade
    backwards and forward those little spindles are just
    going to rotate round and round. You should be there forever trying to
    hacksaw the bolt through.



    Now this particular lock comes in two different finishes.
    It comes in brass and stainless steel which is this
    particular one here. And on the face plate, I don't
    know if you can zoom in - oh, we've got it upside down, if you zoom in you
    can see the British standard kite mark there which is
    what we call it. So the key, this is the key here,
    beautiful, again well engineered key, solid full fixings here and
    the back of the key is all welded with a nice box key for strong
    stability and strength. This is what this key is all
    about. It comes as standard with three keys. There's
    the three keys for this particular type of lock.



    What I'll do now very quickly is i'll give you some
    measurements. This is the three inch lock case. It comes
    in a two and a half inch case as well. But I got the
    measurements here. So what you need to do is take a half inch off the
    measurements, and that will give you some sort of an idea
    as to what the two and a half inch lock measurements would
    be. And, of course, they will be displayed on our website
    anyway.



    One of the distinct differences with this particular lock
    is the actual back set measurement are different to
    the universal set. They always have been different. I don't
    know why, but when they decided to build these locks they decided to
    move the back set a little bit different. So it's important to
    know if you're retrofitting this with any other
    British standard lock, you may find it's going to be slightly
    out. It's only out by a couple of millimeters, but it is actually out.



    So let's get some quick measurements just to get you guys
    some idea.The case deck there is 80 millimeters. The
    case height is 108 - let me get that down there - yeah,
    about 108 millimeters. The fore end then is 150 millimeters. Fore and
    width is 25 millimeters. The back set measurement now, that's
    from the leading edge here to the centre where you
    put the key in, that there is 53 millimeters or 54, 54
    millimeters.



    So there you go. This is the new Union 3K40. I hope this
    video is explaining a bit about British standard and more
    importantly explained a little bit about this
    particular lock. If you're a discerning client and you're looking for good
    security, guys, seriously consider this as being your
    choice. We can do them keyed as like as well. So if you
    put a dead lock a little bit further down with a dead lock on the
    door and a sash lock In the centre, then we can key them all alike so that
    one key fits all. So we can whatever we like. We can do it
    any way in-house.



    I hope this video has given you a little bit more
    information about what you would normally expect in a
    photo with some text. Hopefully this lock may be the one for
    you, but if you need any more information, feel free to give us a call or
    pop online or pop us an email, we'd love to talk to you.



    Anyway, in the meantime thank you very much for taking the
    time to watch this video. Catch you real soon. Take
    care. Bye-bye now.
