Balanced Door Space Requirements
Ellison balanced doors can be manufactured from 33" wide to 48" wide. To accommodate door widths greater than 39", the Type A arm measuring 7-1/8" wide is replaced by the Type C Arm measuring 8-7/8" wide. It's important to identify the space requirements on both sides of a balanced door based upon the width of the door. This chart provides these dimensions as X and Y measurements. For example, a 36" door opening to the outside will require a Type A arm and produce an interior projection (Y) of 12-1/2" and an exterior projection (X) of 23-1/2".
