Passthrough Clearance Single Bookcase Doors

Passthrough Clearance refers to the available space within a doorway that allows people, furniture, or other objects to move through safely and comfortably. In the case of a bookcase door, a portion of the doorway is occupied by the door's depth, leaving the remaining area known as "Passthrough Clearance."

In-Swing Bookcase Doors offer a bit more clearance than an outswing door. Please see charts below for both In-Swing and Out-Swing passthrough clearance.

How to Determine Passthrough for In-Swing Doors

  1. Your Door's finished size
  2. Subtract 6-7/8" (6.875) from your doors width
  3. Total=E Passthrough Clearance

Example: 36" wide door -6-7/8" = 29-1/8 (E-Passtrhough Clearance)

D: Min adjacent wall clearance needed for A= 1.5" B=3.5" C=5.5" (C: all Bedroom Organizers, Wine Glass, and Double Sided Doors)

How to Determine Passthrough for Out-Swing Doors

  1. Take your door's finished size
  2. To find "E" for door "A" Subtract door's width by 10"
  3. To find "E" for door "B" Subtract width by 12"
  4. To find "E" for door "C" Subtract width by 14"

Example: for an 8-1/4" Deep Out-Swing Door that is 36" wide the passthrough clearance is 26"

D: Min adjacent wall clearance needed for ABC= 1.5"

Protrusion

The protrusion refers to the distance that the rear of a bookcase door extends into the room behind it. To calculate  the protrusion (E) you'll take the overall depth of your bookcase (B,C, or D) and subtract your wall depth (A).

Example: You want an 8-1/4" overall depth bookcase that will be installed in a 4-1/2" deep wall. "B" - "A" = "E" (8-1/4"- 4-1/2" = 3-3/4", E= 3-3/4")
