Yale Sloten P121WE raamklem

This window lock was ideal for our metal awning window. I needed a lock to replace one bought many years ago. Easy to use and apart from the key provided needs no other tools or skills.

This is the ONLY window clamp which is superbly made and reliable.

Good value and as easy to use as expected

Very simple and very effective... no drilling, fixing or glueing. Good for timber and metal windows

A bit fiddly to install but appear to be doing a satisfactory job.
