What are Sash Jammers?
Sash Jammers are UPVC levers that are designed to be installed internally or (externally via a locking version) by securing to the frame at specific areas. This significantly strengthens the window against attempts being made to open the window using an object such as a crowbar.
They are simple to use in that once installed the user simply closes the window and then moves (or locks) the sash jammers lever over the frame area that opens as pictured below:

Can I fit Sash Jammers myself?
Yes you can however, like most security products, they need to be installed correctly and professionally to maximise the usage and more importantly the defence they offer.
Our advice is to have these and other security products installed correctly by experienced professionals like ourselves as home security if installed correctly is a fantastic thing to have in place.
Be aware of You Tube type videos claiming everything is easy to do and install yourself. The installation of sash jammers involves drilling holes into your window or door frame at specific areas to strengthen the windows security against attack. If done incorrectly, it could be an extremely costly mistake!
Where should sash jammers be installed?
It is important to confirm that as a company we strongly advise that sash jammers are not installed for use with UPVC doors but in theory they can also be used for UPVC doors for additional security if you wish.
The reason for this is that UPVC doors/ composite doors should already have installed adequate Police approved (Secure by Design accredited) PAS 24 multi point locking mechanisms which makes “spreading” the door open extremely difficult and certainly not a quick and easy task.
It has fast become a house insurance requirement that external doors meet the PAS24 accreditation requirements. We advise for maximum security that for each door or window, 2 x sash jammers should be installed. One in the top area and one in the bottom area.
What is the best Sash jammer?
There are various versions of sash jammers that either include models that are lockable with a key or versions that come without a key.
SheffLOCK advise that sash jammers be lockable, this is so that should a Burglar smash a window they cannot simply reach in, undo the sash jammer by hand without a key and then proceed to lever open the window.
Remember criminals are forensically aware and do not want to climb through windows and broken glass as there is a significant chance they may cut themselves and leave blood at the point of entry.
