The TSS Mortice Sashlock Rebate Kit is an essential component for installing standard mortice sashlocks onto rebated double doors. In applications where the meeting stiles of a double door set overlap, a standard lock cannot be fitted flush without a rebate set to bridge the gap and accommodate the stepped profile of the door edges.

This kit is typically used in residential and commercial timber door installations where a sashlock—a lock containing both a latch and a deadbolt—is required. It functions by providing a matching profile that allows the lock body and the strike plate to sit correctly against the rebated surfaces, ensuring the latch and bolt can engage securely and operate smoothly.

Whether used in a new installation or as a replacement part for an existing door set, the rebate kit maintains the security and aesthetic integrity of the doorway. It is compatible with a wide range of TSS mortice sashlocks, providing a reliable solution for securing double leaf doors.
