Sash jammers are uPVC levers that are designed to be installed internally, or externally with locking mechanisms, to provide added security for doors and windows.

They are one of the simplest and most cost-effective ways to significantly strengthen your doors and windows and can be used in uPVC, composite and wooden frames.

Sash jammers are widely used as an inexpensive security measure to strengthen doors and windows.

A second line of defence they strengthen a door or window to prevent entry even if a lock has been damaged in a break in. This makes them a widely used method of added security.

They are easy to fit and can be used on most types of doors and windows.

Three quarters of burglars gain entry through a door, so installing sash jammers on uPVC doors is a great way of reinforcing your home.

Easy to install the sash jammer handle pivots and is secured over the frame offering resistance which in turn prevents a forced entry.

With one third of burglaries, gaining entry by forcing the front door lock, sash jammers provide added peace of mind as once activated even if the door lock is forced open the sash jammers will work keeping the door closed.

Although a great added security measure there are a few things you need to be aware of when using a sash jammer. The devices use a lever mechanism so over time can become loose and less effective. It is important you keep up to date with maintenance and think carefully about whether you need internal or lockable sash jammers. There are differences with both, so it is important you think about all the pros and cons.

• Do you want them to be activated when you are outside the property?

Internal sash jammers only work when you are in the property as you need to activate them from inside. Lockable sash jammers have a lock on the outside of the frame, and you can activate them as you leave the property as well as when you are at home.

• Be aware they can restrict access too

Keeping burglar outs is ideal. However, if you are in your home and have activated an internal sash jammer then nobody else can easily get in if you are unable to open the door for yourself. It is therefore important when fitting sash jammers you think about how you may want to use them and whether external or internal options are best. If you fall or need a career to be able to gain access in an emergency lockable sash jammers may provide more flexibility.

• Loose fittings can unintentionally activate sash jammers

As sash jammers become loose over time they have been known to drop down after the door has been closed so it is important to keep an eye on your devices and carry out regular maintenance. Sash Jammers lock doors tight so if they can only be accessed internally and the sash jammer has dropped after you have closed the door it makes it impossible for you to get back into your house even with your house keys.
