Looking for a secure locking solution for timber French doors?
The Winkhaus UK FAB slave door locking system offers a streamlined option for double doors, without the need for a separate handle or cylinder on the secondary door.
The integrated two-way lever operates heavy-duty 20mm top and bottom shootbolts, while the main door multipoint lock secures the two door leaves together.
Key benefits include:
> Flush integrated lever for simple secondary door operation.
> 20mm top and bottom shootbolts for secure locking.
> No additional second leaf door handle or cylinder required.
> Flexible sizing, suitable for taller French doors and unequal door leaves.
FAB double door kits are available through BJ Waller, with individual components also available to order.
