Safety Window Restrictor

I was looking for a well built window cable lock, and came across this one. Many restrictors that I found were cheaply made and the "lock" was little more than something that could be turned with a flat screwdriver. HOWEVER the Jackloc restrictor has a 5 lever lock, with a proper key. The cable is securely fitted and I can see that this will last a lifetime. I chatted by email with the company (in the UK) to ensure that this would meet my requirement, and I'm very happy to say that it does. I even have one fitted to my front door (instead of a door chain). Having the ability to unlock it, means that even if one of us is out and the other is using the restrictor, I can unlock it to let myself in. Not having a Canadian distributor is a bit awkward, but the extra shipping costs were worth it. I would definitely recommend it.

Nice quality product. Easy to install and provides piece of mind. We have an adventurous child, and live in a high rise condo.

These are easy to install, and give comfort having them in our grandaughters' fourth floor bedrooms. They interfere with screens though, so we had to cut a slot in screens .

This worked perfectly to secure the window in our toddler's room. It was very easy to install and I like how it can easily be unlocked in case of an emergency. My only complaint is having to drill holes in the window frame.

Good Quality, but has only one key

Found our eldest, aged five, climbing on his bedroom window ledge recently and decided this was a necessity. Now have these on a single window in each of our kids bedrooms and feel much happier leaving them open at night and during the hot summer days. Fitted very easily and quickly to our uPVC windows. Just needed 3mm holes drilling for all x4 mounting screws. Locking mechanism on one part of window and security lead on the other. As others have said, the x4 security screws are a little OTT and unnecessary, that said I have used them just fine on both of mine. Slightly more fiddly to tighten up and once screwed in they aren't easily removable so you only get one shot to get them right. The only downside to this in my mind would be if one of your fixings didn't hold too well, you wouldn't easily be able to remove the screw without drilling it out. Build quality on this product is superb though, really well made, solid. Decent key mechanism. One key fits all all locks in case you lose one. Would certainly buy this again over a cheaper alternative.

Very pleased with order and service.

Just moved to a bungalow and bought two of these because of needing to keep cats in for a while but wanting to open the windows. They're really excellent but I'm glad I read other people's advice about not using the screws that come with the set as they're the type that can't be removed without removing the whole thing (I'm not sure if that's right but it's something like that!). It was easy enough to get alternative screws. We've mounted the lock not in the centre of the window as shown in the pictures, but at the bottom of the window (modern pvc double glazing type) so the bit that's attached to the window isn't so 'in your face' if you like, plus the added bonus was that instead of attaching the other end to the upright pvc part of the window, we could attach it to the strip along the wooden windowsill. So the whole thing works really well but is much more discreet than in the photos shown. Very good for a sense of security at night too during the summer for having windows open on the ground floor. It's given the cats a chance to sit by the open window without escaping, until they get used to the place. They're excellent quality too (the locks, not the cats! Well the cats are too of course!.)

Very good, does what you buy if for, cable length just right for my windows. I bought 7 of these and one key fits all locks You may not want that, But its not a lock to keep out intruders, its to keep children safe, so I am not that bothered. The lock was easy to fit, although I did not use the supplied security screws that can not be easily undone I used regular pozi head screws. My only grumble is, there are no caps supplied to conceal the screw heads on the part that is on the end of the wire flex yet there are supplied caps to conceal the screw heads on the locking side. That's a minor cosmetic thing so its still 5 stars from me, as this is a good, sturdy, easy to operate child safety lock. The price is a little high, compounded if you need a few of these but..... Better safe and worry free than buy a budget priced lock that may not do the job properly
