What are sash jammer locks?

Question

How do sash jammers work and can you install them on standard uPVC patio doors?

Matt · Answer

You can install them on any upvc doors or window they can either be used for extra security or a temporary repair for example if your window handle or mechanism fails you can lock the window using a sash jammer.
You can also screw the sash jammers to a upvc door frame for more security one at the top and one at the bottom. 
I hope this helps you

Yes they are little arms that pull across the door against each other. They’re inexpensive yet really effective. They screw straight the door or frame.

Mark · Answer

They are locks to restrict the amount you can open box sashes.  Not recommended for doors. I can supply and fit locks for  patio doors.  Thanks. Mark

Sash jammers are small devices that can improve the security of your uPVC windows and doors. They attach near the window or door frame and pivot over the door or window securing it into place, offering another level of security that can help prevent forced entry.
Yes you can do install any upvc window or door .

James · Answer

A sash jammer is a secondary device that screws to the door frame and turns to block the door from opening.

They aren't considered a high security solution.

They can fit onto most upvc frames, some are available with a locking function.

As long as the doors open out and are not sliding they just fix on the frame and stop the doors or windows from being pushed inwards
