Specification advice – door handing
14 October 2016There are a number of methods used to describe the handing of doors. The technique we use here at Denleigh is described below.
Internal door handing
The handing of a door is determined by the side the hinges (or pivots) are on the door viewed from the hinge knuckle side. For example if the hinge knuckles are on the left, the door is left handing. This is depicted on the diagram below.
On occasions when there is a master and slave door, the handing refers to the master door which opens first as per the methodology for a single door.
External door handing
Exactly the same technique applies for external doors, however additional clarification can be provided be confirming the door is viewed from the ‘outside’ of the building and by identifying whether the door ‘opens in’ to the room or ‘opens out’ of the room.
