Hi, guys, my name's Darrel, and I'm head of the tech team here at Thanks for taking some time to tune in and have a look at one of our product review videos.

Today we're talking about strike releases. We're going to talk about the company EFF, which is a subdivision of the Assa Abloy group. This is the 14-34 Electric Mortise Electric Strike Release, so let's get up, and let's have a look in a bit more detail.

Now, this is what they're calling as their traditional range, the standard, basic range. It's designed typically for light duty. It's not a heavy, industrial sort of strike release. Of course it can be fitted on either that position there, or that position depending on your particular application.

Now, this is also available in 12 volts, and it's available in an AC and a DC, and it's also available in a fail-locked and a fail-unlocked solution. So let me give you a little bit more information about fail-locked, and fail-unlocked, because it seems to confuse some sort of people, in regards to how you work around this particular type of application.

Now, in most cases, you want a lock to be failed–locked, so when there's no power being applied to it, the actual lock is in the locked position, which means that the door is not in free access. But, in some applications, it may be like a fire alarm system, or part of a means of escape, or an emergency, that you want to have the power there permanently, and if the power was to be de-energised because there was a fire in the building, or the power was to fail, for whatever reason, and you want that door to be free to access, then you would go for a failed-unlocked version.

So, that's the difference. So, you might hear the words fail secure, or fail safe, as well in the industry, in how we regard the difference between the two. So that's well worth knowing.

Now this particular one has got a relatively deep jaw, in comparison to some, and the jaw there exceeds 9 millimetres, in regard to its measurement. So, while we're talking about measurements, what we're going to do is spend a couple of minutes now, and I'm going to actually measure this strike release up for you.

So, if you have the badge that you might see on your strike, which is just sitting up there, if you could zoom in, I don't know if you can actually see that. So, if you've got that, and you think to yourself, "Right, okay, I know it's an EFF strike" let's get some measurements and let's see whether or not this is the one that you have.

So, the forend length, that's from one end to the other, there is 150 millimetres, okay, that's the fore end then. The forend, the width there is 25 millimetres, they're pretty industry standard. The depth of the jaw, as mentioned before, is just over the nine millimetres, that's how you measure the depth of the jaw. The height of the jaw, that's the clearance height of the jaw, is 43 millimetres, yeah I'm gonna go for 43 millimetres, and the depth of the actual lock itself is 30 millimetres as you can see there, and the width of the actual locking chamber is 20 millimetres as you can see there.

Now, you may find that you might have soon met specifications sitting on the back here, this is obviously the 14th version, or the 14-34 version, okay? So, if you've got writing similar to this on the back, then at least then we know that we're in the right foot park, in regard to the strike that you might be looking to want to use.

Bear in mind, guys, that this particular strike is only designed really for back duty, so, you know, maybe a small group of flats, or something like that, is all you would be expected to be using this for. Don't go looking and putting it on the fore end on a four court, where it's being used 20, 30, 50, times and times a day, because it isn't going to last. It's designed to be for a light duty application.

So, if you need a bit or information, or if there's something that I haven't mentioned there, by all means, pop us over an email, use the live chat on our website, or by all means just give us a call over the phone. Anyway, we'd love to hear from you, and more importantly we'd love to see you as our customer.

So from me, Darrel, and all of us here at the LocksOnline team, I hope this video has given you a little bit more insight into this particular product, and at least you can see it in the flesh, and try and make an understanding whether or not this is the lock that you're looking for, the electric strike that you're looking for. Once again, take care, and we'll catch up with you again real soon. Bye-bye now.
