There is a channel that runs along the bottom/edge of the window. If you don't have a channel, they won't fit. **Q: This steel is not corrosion resistant. What protects it from rusting on the window?** A: nothing protects it as such--however the design means it is fitted inside(protected from rain etc)hence no damage from weather etc? **Q: It seems like it should work, but it stops the window from fully shutting as it hits the frame, I'm I doing something wrong?** A: Did you screw it inside the window correctly? If it’s only not shutting due to a few millimetres then I expect you have fitted correctly and may need a ‘UPVC run up riser/window riser’ you may actually find you already have one that you can slide along the frame and move closer to the new latch. This should ease the window slightly over the new latch **Q: Can these be used on metal frames** A: I successfully fitted two sets to different metal framed windows, but: 1. Supplied screws supplied are unsuitable for metal, so use short self tapping ones into drilled pilot holes (make sure they don't hit the edge of the window unit inside the frame!). Rivets don't seat properly as restrictor holes are countersunk. 2. Some types of metal window don't have grooves to locate the restrictor into, so careful measurement is required to achieve a good installation. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product *by M***S on 12 July 2024* Good fit and value for money good adhesion and high safety and performance ### ⭐⭐⭐⭐⭐ Easy to fit and seems to be doing the job *by I***N on 30 August 2023* Easy to fit. quality seems ok.

Delivered on time ### ⭐⭐⭐⭐ Work Really Well, Slightly Fiddly to Fit *by M***Y on 24 August 2018* As noted by others, these don't come with instructions - for the most part I didn't mind that as it's quite obvious how they work, but with the exception that no guidance was given as to whether to fit the arm to the casement (the "window") or the frame, however if you look at the images for the left hand product (the HS4318) it does show to fit the arm to the casement, which I definitely agree with as it makes it less fiddly to open the catch, note that I saw another reviewer advised fitting it the other way round, which I think would make it tricky to open. Generally all went fine with installing these, I had seen another reviewer had managed to fit them without a ladder (on a second floor window) - I personally wouldn't advise this! It's quite tricky and I think it will make it more difficult, I used a ladder and it was still a bit fiddly. As noted in one of the images, I had to put a small bit of a plastic in order to move the arm down a bit as it was contacting the pin at the top bit (the part like a mushroom) and wasn't closing well, I just used a bit of plastic trunking to do this, and I fitted it to the casement part purely because it makes it less visible. A good bit of advice would be to do a dummy run on a downstairs window because then it's less stressful to figure out all the alignment. If you have some double-sided sticky tape to temporarily mount the arm and pin that would be great as it would let you test closing it too. I did have a bit of an issue getting the bases of the pins to sit in the window frame - you'll notice that one of the images I've uploaded shows the base of the pin to have some slight damage - this is from having to use a screwdriver and a bit of hammering to get it in, and you might also notice a (admittedly very tiny) amount of deflection in the plastic frame, this is because the base of the pin was ever so slightly too large for the euro groove in the frame, and as such it got deflected a bit. Also of note is that the screws - one set (I can't remember if it was the left or right handed one) came with brass screws, whereas the other came with nickel screws, which I thought was a bit rubbish! I ended up using the brass screws for the arms fitted to the casement, as you can't see them, and used the nickel ones for the pins which you do see. All in all I do really like - a very very tidy way to child-proof your windows, and I don't think the installation was excessively fiddly (I think some fiddling is to be expected), but I'll mark down a star due to the screws and lack of instructions. ## Frequently Bought Together - HomeSecure HS4318 UPVC Window Restrictor Hook with Child Lock Restrictor Safety Catch - Silver - UPVC Window Restrictor Hook.
