Passthrough Clearance

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 hidden double 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.

*Important: Max Wall/ Jamb Depth for all In-Swing Bookcase Doors is 6-1/2" No restrictions on outswing doors

How to Determine Passthrough for In-Swing Doors

  1. Your Door's finished size
  2. Subtract 13-3/4" (13.75) from your doors width
  3. Total=E Passthrough Clearance

Example: 48" wide door -13-3/4" = 34-1/4" (E-Passtrhough Clearance)

D: Min adjacent wall clearance needed for A= 1.5" B=3.5" C=5.5"

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 21"
  3. To find "E" for door "B" Subtract width by 25" *(min passthrough warning on 48" wide doors)
  4. To find "E" for door "C" Subtract width by 28" *(min passthrough warning on 48" wide doors)

Example: for an 8-1/4" Deep Double Out-Swing Door that is 48" wide the passthrough clearance is 27"

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

*Passthrough Warning: smaller width doors with deeper shelf depths have limited passthrough clearances on outswing doors TIP: if this is a concern see IN-Swing Double Doors

Protrusion

The protrusion refers to the distance that the rear of a bookcase door extends into the room behind it. To caculate 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")
