A rebate for a French door is a type of lock that is designed specifically for double doors or French doors. A French door typically consists of two doors that meet in the middle and close against each other, with one door typically being passive and the other being active. The rebate lock is designed to secure the two doors together, providing a high level of security and preventing the doors from being forced open.

The rebate is a groove or step that is cut into the edge of the door that allows the two doors to sit flush with each other when they are closed. The lock mechanism is typically located in the active door and it includes a latch bolt that extends into the rebate on the passive door, providing a secure connection between the two doors.

Rebate locks for French doors are available in a variety of styles and designs, including deadlocks and sash locks, and can be operated by a key or a thumb turn. They are often used in residential and commercial settings where security is a concern, and are particularly useful for securing external doors that open outwards.

Overall, rebate locks provide an effective and secure way to lock French doors, and are an essential part of any security system for this type of door.
