Hi, guys. My name is Darrel and I am head of the tech team here at LocksOnline. 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 and hopefully a little bit more detail in the flesh so to speak, and obviously help you make a bit better of an informed decision as to whether or not this is the product that you are looking for.

So today I want to show you a centre roller shutter door lock that we have on our website. It is manufactured by the company Tessi and this is the actual product here, as you can see.

Now, some of the distinct advantages of this particular type of lock over maybe some of the competitors out there is you do have the ability to be able to operate this particular lock, if I just put the key in there I can operate it from the outside, which would be the outside here, and I can also operate it also on the inside there as well by turning the actual lock that way as well. So it doesn't matter which side of the door you are at. If you want to unlock it or lock it, then you have the ability to do so.

Most of these locks that we sell here are for the replacement industry, so if you know that its got Tessi it is going to have Tessi written on the actual barrel there so that's good telltale sign. The actual size of the actual barrel, because that may be all that you are able to see at this particular moment in time, is about 25 millimetres. So that's quite important for you to be aware of also.

While I have a steel ruler here, let's get some measurements of the actual case size as well for you. So the actual overall length of the actual lock itself is 156 millimetres. The actual case height, I would put that at 41 millimetres. Also the fixing centre is here, so the fixing centre there is about I am going to go with 142 millimetres there and then these fixing height centres here is around about, I'm going to say, 27 millimetres.

Now, another important thing is how far does this project when you actually lock the unit. So at this moment it's in the unlocked position so if I was to measure that there I would get around about 24 millimetres and that centre point there is around about 15 millimetres there, as you can see. So when I put the key in and I put it into its locked position there and pull the key back out, that is now projected out to the overall length is about 44 millimetres, maybe 43, 44 millimetres and that fixing centre there now is now 35 millimetres, so it throws quite a significant distance there.

So there you go, guys. It's available on our website. It comes standard with two keys. They are available via special order to be keyed alike as well if you need them to be keyed alike. But there you go, that's the actual product. But listen, if you need a bit more information or you want a bit more advice, pop us over an email, use the live chat that we have or simply pick up the phone and give us a call. Either way, we would love to hear from you and more importantly we would love to see you as one of our customers. For me, Darrel, and all of us at the team, thanks for taking the time to tune in and hope to catch up with you real soon. Take care now. Bye-bye.
