Lxoraziy 2 Pieces Adjustable Position Casement Window Restrictor Latch, Lock Tilt Regulator for Windows, Child Lock Restrictor Catch for Aluminum, Wooden, Metal Window and Door(Black)

Very simple to attach, very sturdy.

Great product for our bespoke modern windows.Less 1 star as the screws supplied for the black window stay are NOT black as per photo but silver so look awful. I had to source my own at extra cost.

Does what it says on the box !!!!

Keeps window restricted during wind, stoops it flying open or slamming shut as I need to sleep with the window open. As per description, don't apply parallel, put the hook slightly lower down. Used screw driver function on drill to install. Brilliant purchase. I bought a 2 pack, one for a friend to keep his patio door closed to, so his cats can come and go. Also works perfect for this

This product is perfect for letting the air get into the room without the naughty animals.

they keep my doors open.

Good quality, good price, good screws to fit it on a plastic door.

Great window opening latch, easy to fit and works really well. Just ordered another one.
