FAB Slave Door Locks

Shootbolt keep rails with integrated shootbolts

The Winkhaus FAB slave door lock range provides a high security locking option WITHOUT the need for a security kitemark cylinder, cylinder guard or a security handle.

High security locking without the need for handles, cylinder or dummy mullion

The lock is operated by a flush, integrated two way lever the FAB slave lock throws two heavy duty 20mm shootbolts into the head and cill. Combined with the renowned Cobta or Trulock+ multi-point lock on the master door the locking hooks penetrate the FAB slave lock to secure the two leafs together.  No additional hook keeps are required.

Unlike conventional PVCU double doors a dummy mullion is not required, which can dramatically reduce sightlines.  The FAB system requires doors with opposing eurogrooves.
