2Pcs Window Locks for UPVC Windows, YTOOK Adhesive No Drilling Window Restrictor with Key, Pet Window Safety Locks for Childproof, Easy to Install

These are really easy to install with a simple sticky pad which has held up without me screwing into the frame and as a double kit they're great value for money. They mean my indoor cat is kept safe and we can still have our windows open. They look smart and have proved to be good quality so far. The key for locking seems sturdy and easy to open and operate which surprised me as sometimes these things are flimsy, but I recommend these ones.

What a great item. I was concerned that they wouldnt stick well as I was unable to screw into the window but they work great and would definitely recommend

So easy to put on window frame. Adhesive is so strong.

I am absolutely delighted with these.You can stick them at whatever restriction distance you choose, which is fabulous for my new little cat, Louis (meaning I’ve set mine to half the wire cable length).They are so easy to install but make sure you thoroughly clean the area you want them with the alcohol wipe (sadly they only give you one per packet of 4 & I’ve bought 8 in total). Luckily I’ve always got pure alcohol in my cupboard, so I could fix them all when they arrived.Be careful if you’ve got narrow window frames because you’ll have to elevate the connector part, so your window will close properly. I made a mistake on one of the bedroom windows because I’d stuck it too low on the frame.It took me nearly half an hour to remove it…. The glue on them is spectacular and you won’t need the screws , take my word for it!These get 5 stars ⭐️ and 10/10 from me.

Came ontime. Works a treat

Value for money good safety we used them on upstairs windows that are always open , now wind can’t open them more

They were easy to fit no drilling needed and they do the job well , very strong

Easy to fit and value for money
