MODERN Burglar Avoider Sash Blocker And Cable Restrictor With Alarm White

The MODERN Burglar Avoider Sash Blocker And Cable Restrictor With Alarm is the first of its kind, combining a sash stopper with a contact alarm and cable restrictor to suit most doors and window frames. Not only does it protect the home from burglars, it can also aid in child safety, preventing doors and windows being opened by children without permission. An alarm sounds when an attempt is made to force the door or window opening, with a 110db sound output, whilst also preventing the door or window opening if someone does try to break in.
