Flush Fitting Locking Sash Jammers have become a popular product here at Spares 4 Repairs, these provide additional reinforcement to the locking mechanisms on doors, particularly those with flush-fitting surfaces like Composite Doors. These can however sometimes be found on modern flush windows also, so are not exclusive to just Composite Doors.

Sash jammers work by jamming the sash (the moving part of the door) against the frame, this prevents the door from being opened even if the main lock is compromised by a potential intruder.

We are sometimes asked how to fit these flush sash jammers to both composite and timber doors, with that in mind we have created a video tutorial explaining what they are and how to best fit them to both composite and timber doors:

Included with the sash jammer are 3x studs to suit variety of profiles, 2x block packers and 2x screw cover studs, essentially everything you need to install the sash jammer.
