The Union 2979 Sash Lock Rebate Set is a specialised accessory designed to facilitate the installation of the Union 2979 mortice sash lock into timber double doors. When doors feature a rebated meeting stile—where the two leaves overlap—a standard flat strike plate cannot be used. This rebate set provides the required offset to bridge that gap, ensuring the lock functions correctly and maintains the door's security integrity.

Constructed for durability and precision, the set is fully reversible, allowing it to be fitted to either the left or right-hand door leaf without modification. It is typically used in residential or light commercial applications where French doors are installed, serving as a critical component for both new installations and the replacement of existing hardware.

The set includes the main rebate body and the strike plate components required to house the latch and deadbolt. By using this dedicated rebate set, installers ensure a professional fit that prevents binding and allows for smooth operation of the locking mechanism within the door frame system.
