Hi, guys. My name's Darrel and I'm 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. Today we're looking at the Winkhaus window safety catch restrictor.
It's designed to work with UPVC windows and what the idea of this particular device is doing is an accessory to your window and allows you to open the window to a predetermined position to allow you to get ventilation, but at the same time restrict it from opening all the way which means that it can be used as like a child safety device if you've got a window up on a first floor and the child can actually get out and, of course, that's the last thing all of us don't want. So it's actually designed around UPVC windows and I'll get it out now and try and explain to you its operation and how you go about fixing it to the actual window.
So this is the actual main device. Now as you can see here, you've got some countersunk screw positions there and you've got some countersunk screw positions there. Therefore that means that this can be either sitting on the left-hand side of the window or on the right-hand side of the window, depending on which way you want it to go. Now, what basically happens is you've got this keep that will sit on the actual window itself. This would normally be bolted into the frame or vice versa. It depends on whether your windows inward open or outward open so that allows you to fix to a flat surface whereas this allows you fix to a side surface.
Now bear in mind, guys, that this particular lock doesn't come with screw fixings. The screw fixings will have to be supplied by yourselves and I would suggest that you use countersunk screw fixings. The purpose of that is what you're trying to do is you're trying to get into the actual metal of the actual steel within the window, if you can. So it depends on your particular making application of window as to how far that steel, if any, is actually in your window so just be conscious of that.
So the idea, this is the locking version and if you were to zoom in there firstly you will see that there's an Allen key there and it allows you that if you were to turn that out a couple of turns it actually stops the operation in either the open position or the closed position. So it is actually treated as a window lock as well. Now the principle is quite straightforward. This you would bolt onto the actual window itself, this typically would be on the frame. They would sit in there like that and effectively what would happen is once you'd operate that and it would sit there then like that so you wouldn't be able to open it any more than that.
And when that's in that position there, again, you can alter that Allen bolt in there and that will allow you to lock it into that position. When you want to close the device, it's quite simple; I'll just put this down for ease of operation. You would, in effect, push this unit here and that allows that then to push back in there, like that, and that is how you can lock it back into position.
So there you go, guys. It's quite a nice piece of equipment. It's obviously designed and manufactured by a reputable company, Winkhaus, and of course is designed specifically for UPVC windows. If you need a bit more information on it or you want some more technical advice, by all means, give us a shout. But what I'm going to do now is I'm just going to quickly go through some quick measurements just to give you some sort of idea if you think, oh, this is ideal for you, then, and you want a couple of measurements, let's see if we can get those for you now and then you can probably offer those measurements up to your windows to see if it would actually fit for you.
So this is the part that would normally go on the window itself, if it's outward opening, and the width of that there is 14mm, and its overall length is 98mm, overall length. Those centre screw fixings there, for your information, is 50, I'm going to say 54mm, they're about 50mm, and this is another fixing centre here, which allows you to hold to that fixing centre, if you wanted to, on that serration there as you can see there. So that gives you an idea of what that overall measurement is.
If I was to pop that on there, I'd give us all some sort of idea as to the opening. The opening is about two inches there, guys, if you want to know that. The actual length of this particular part, right from the end, right to the top, is 150mm and its width of this thickest part there is 17mm, and that width there is 16mm.
So there you go. I hope that's enough information for you to make an informed decision as to whether or not this particular type of window restrictor is suitable for your application. But, listen, if you need a bit more information or you want a bit more advice, by all means use the phone, give us a call, use our live chat, it's totally free on our website, or just pop us over an email. We'd love to hear from you and, more importantly, we'd love to see you as a future customer.
