The present invention relates to a flush latch locking mechanism for a door. In our experience, the locking member of prior art flush latches intended for use on doors 27 mm thick only travel a maximum distance of 7 mm. Therefore, there is very little tolerance for variation in the space between the door and door jamb if the door is to be held securely in a closed position. The present invention relates to a flush latch, locking mechanism including an operating lever and a retractable locking member that travels between a rearward retracted position and a forward advanced position. The locking member includes a cam surface having a raised portion which is engaged by the lever in operation so that the locking member can travel up to 13 mm when fitted to a 27 mm thick door.
