Inside Recess

Measure the drop of the door recess at 3 points and use the smallest one.

Order as Recess Size.

Outside Recess


Measure the width of the inside recess wall to wall then add on 30cm to allow for an overhang around the recess of 15cm either side. Check there are no obstructions.


Measure the recess drop to the floor, then add on 10cm. This will allow for bracket fixings and the head-rail.
