eSynic 4 Pack White Child Safety Window Locks for upvc Windows Screw Mounted Window Opening Rrestrictor with Keys 185mm Long Wire Window Safety Latch for Baby Cat Home Office Safety etc

Great product, really easy to install, you can position them differently for how much you want your window to open. And can always open them fully with key. Great extra bit of safety for children.

These are brilliant for keeping pets inside, they are full adjustable as you can position them wherever suits you. A must for indoor cats and dogs.

Very easy to install on the outside of my uPVC windows. Bit worried about how much force each one can withstand, as the cable covering isn't the best and may oxidise with age.

I needed these to stop some third-floor windows opening too wide and they fit the bill just fine. They were easy to fix and seem pretty secure, plus they have a lock so they can be opened fully if required. I needed ten of them and this was the best price I could find.

Great product, good value for money. Really easy to fit. I brought for my 3 years old bedroom. We fitted (screwed in, not adhesive) one under the window handle, it looks neat and still opens to let enough fresh air in with peace of mind.

Bought for my child. Came apart first use. Absolutely shocking, string is safer.

They are easy to install, and reliable. I get the feeling they will last years and years, giving us confidence the windows be safe for kids whilst being slightly ajar to let fresh air in.

Stops children opening windows too wide.
