Fixed Sash Jammers

Fixed Sash Jammers

Fixed sash jammers stop the levering of a windows sash leaf from the outside – greatly protecting the window from being accessed by an intruder.

The fixed sash jammer is small and simple to fit device that does a big job! Once installed the sash jammer physically stops the burglar from forcing open the window. More specifically it protects against an intruder prying the sash leaf from the window and forcing entry – a very common burglary method.

How does it do this? The fixed sash jammer offers resistance from the inside when pressure is applied to the window from the outside. It is fitted to either the window frame or the inside panel depending on whether it is an inwards or outwards opening window (it also comes with packers to make a secure fit on your window.) When the locking arm is moved 90 degrees to its locked position, the window is secured. It is very easy to operate even for people with arthritis or limited hand movement!

The fixed sash jammer is sturdy and robust, made with a durable metal and including secure fixings. When fitted properly the fixed sash jammer proves very effective against sash levering. It is recommended that the sash jammer is locked in place anytime a window is closed and unattended.
