For failed multipoint lock mechanisms which cannot be released by the usual methods.
This is a ‘backtrack’ based kit. It is specifically for UPVC doors and windows where the mechanisms have failed and cannot be released. It is ideal for shootbolt only systems and those which are rusted or broken and will not release using normal methods.
It is also ideal for small windows which are impossible to open with regular tools. It works on both windows and doors and requires removal of panels and sealed units to gain access to the
back of the door or window sash.
