eSynic 8Pcs Window Restrictors for UPVC Window Opening Restrictors Screw in Window Safety Locks Children with Keys Kids Window Catch Velux Window Lock Perfect for Home Public Applications-White

These were easy to install and fit for purpose. Gives you a decent amount of open window space but not large enough the cat can slink through and also will prevent little ones from being able to get more than a hand through the gap. Good value for 8 in a pack. Decent quality materials used and feel strong and durable.

great little catches i love that same key fits all easy to use quick and easy to install , iv used them on upstairs windows with young children and they withstand great product and great price

Easy to install,works well so I can have windows open a little bit :) without worrying about the kids getting in the window and falling out (obvs I never let them stay there without me being close by)

These are good for fixed restrictions to windows. Got them to limit my windows to stop cat escaping. Difficult to get the gap just right. As it involves drilling holes in double glazing frames, not great. Would be good if you could fit the anchors and then adust the gap.Wiuld be better suited for ppl looking to stop small children opening windows too far open or for added security when leaving windows open.Good quality, not visually intrusive. Recommend

Would 100% recommend.These safety catches are easy to fit & open wide enough to let in enough fresh air.

They are very good for windows as a restrictor and safety for upper storey windows to prevent falls, in an emergency they can be forced so exit is made possible.They would be even better if self tapping screws replaced the screws that are included.

Have bought this previously and bought again while I was in the UK as it isn't available in kuwait (not very high on safety here😒)Will definitely be buying more when I am I the UK again, not that I need more just the fact that they are amazing quality and are an amazing price ,friends here in kuwait have asked about them so will be good to have spares to give out.

The media could not be loaded. Great ordered another set. Get the fresh air in and the cat can’t escape until I’m ready to let him out .
