Sash Jammers

I actually use these to hold a sash window OPEN. The cords have snapped and access boxes have about 100 years of paint on them. We has a loop and eye before but it wasn't very secure. This works great, screw to the frame open the window then lock in place You have to unlock it to close the window so safe for our dog to put her head out!

Brilliant. Works great. I fitted them to my upvc window, there’s no fitting instructions but it was fairly simple. I positioned them on the frame of the window opening and used a 3mm drill bit to make the holes for the screws. You need about 4-5mm clearance from the edge of the frame to allow for the way the window opens (windows open in an arc). There’s plenty of packers/spacers that come with them so should be enough for most window frame thicknesses. The screws are self tapping and do not need to be over tightened ( hand tight works well). There’s also some caps to cover the holes for the screws. The keys are a bit fiddly to use but a drop of WD40 helped with that.

These were ok, bought as window security, but can be used for opening inwards rear doors, works well.

Very easy to fit even without any instructions in the box. Good for extra security and if placed higher than the door handle it acts as a deterrent for young children to open the door

It s really work,very strong,perfect product

Easy to install. Flimsy not that sturdy at all. Does stop door opening.

Nothing to dislike. Would Buy Again.

Nice product apart from the quality of the finish. Easy to install and appears strong but only time will tell.
