x2 Sash Jammers - Extra Security Locks for uPVC Window & Doors - White

One of the locks on the downstairs windows was a little temperamental in that it sometimes only partially locked the window.So needed something that would provide extra security when the lock decides of have an off day.These worked brilliantly and easy to install. Our bottom frame is quite slim so needed make sure that there was enough clearance so that the locking arm can be moved in to locking position.I said that the install was easy but the screws that are provided seem to have a drilling part at the top. I found that holding the lock while trying to screw the screw was difficult as it did take a little time with the electric drill to cut into the frame.I opted to using masking tape to hold the lock so that I had two hands free to use the drill to screw the screw into the frame.Reflecting on this, perhaps I could have drilled a very small pilot hole which may have been easier.Supplied are two spacers to factor in how thick your window frame is relative to the window. I did not need them.

Well made and a good price value for money and fitted perfectly for what I needed it for

Very easy to put up excellent Quality . Great. All round a very good security product everyone should get them at this price point .
