Rebate Kits: A Potent Solution For Mortice Locks and Latches

Rebates are usually seen with double doors.

1. This reduces draught
2. Gives a nice snug fit
3. Allows privacy

However where a mortice latch or mortice lock is used on a double door with a rebate then a rebate kit to suit the latch or lock must be used.

The term ‘rebated doors’ is usually used to describe a set of two doors which have been cut, or rebated, into one another. To do this, half of the ‘thickness’ of the face of each door is channeled out, usually by 13mm, but also by 19mm or 25mm, so that when they close the doors interlock into one another. This ensures a neat and solid fit when closed, and will help to prevent the two doors from warping away from each other too much after fitting.  When used externally, it also ensures that the doors are fully sealed for much better protection against the weather, wind, and water penetration.

On double doors there is normally a ‘Slave Door' – Meaning one of the doors is bolted in place; and a ‘Passage Door' – The door which is most commonly used for passage, and the door upon which the door handle or knob is mounted.

A Rebate Kit is an ironmongery accessory that is employed to allow a lock or latch mechanism to be fitted correctly on a pair of double opening rebated doors.

The Rebate Kit becomes essential when using a Mortice Latch or Lock on rebated doors as these are designed with standard square edges which do not fit well into the rebated sections. The Rebate Kit provides a shaped surround for the Latch or Lock mechanism that will ‘level’ the rebate on the face of both of the doors at the point where the Latch or Lock is placed – thus allowing the doors to latch into place securely.
