Sash Jammer Fitting Instructions
Sash jammers provide excellent additional home security for uPVC windows and doors. The sash jammer handle pivots and is secured over the frame, offering resistance to deter forced entry.
How many to use?
1 Sash Jammer – Small Window
2 Sash Jammers – Larger Window / Single Door (Top & Bottom Fitting)
4 Sash Jammers – French/ Patio Doors ( 2 Top, 2 Bottom on each door)
1) Locate the Sash Jammer onto section making sure that the window can still open & close without contact with the Sash Jammer Body.
2) Drill 2mm pilot holes into the section using the sash jammer as a jig.
3) If you encounter re-inforcing when drilling pilot holes you should then use the self tapping screws provided.
4) If the pilot holes drill through relatively easily then there will be no re-inforcement and you will need to use jack nuts
Please Note: We recommend using a 2mm drill bit. Jack nuts are supplied separately to our sash jammers. We recommend using a 9.5mm drill bit when using jack nuts.
