Fitting Advice

Sash Jammers are very simple to fit.The first thing you need to do is check if your frame has steel re-inforcing. This is done by drilling a pilot hole into the frame (2mm drill bit recommended). When drilling this hole you should feel tension from the steel meaning you can then drill straight into the frame with the screws we supply.

If there is no tension and the frame is hollow inside you will need to use jack nuts for fitting. Jack Nuts with machine screw to suit are supplied separately. Click the image below and use the 'add to basket' feature to purchase along with our sash jammers
