Most Versatile Model

The new model 480 has a larger receiving area to safely collect exhaust hose whether it's entering the wall at floor level or higher up on a pedestal.

Homebuyers now have complete freedom to choose the appliances that best fit their lifestyle. Stand-alone or pedestal dryer? The 480 can accommodate both.

Contractors benefit from the standard placement that simplifies installation. For added versatility, the uniform corner design allows for venting the recessed connection up or down. Click HERE for more information on 480 versatility.

Installation Instructions

This new model Dryerbox® can be installed in any direction (up, down
or sideways venting) and once installed can accommodate stand-alone
dryers or dryers on a pedestal. Since most standard American clothes dryers
have an exhaust port in the center of the rear panel at the very bottom, it is
best to install this model Dryerbox on the bottom plate (as low as possible),
unless the dryer is stacked over the washer*.

  1. If stud wall is a 2x4 wall, fur out the particular wall ¾” with 1x2 furring
    strips to provide adequate depth.
  2. Situate the Center-Line marking on the Dryerbox to the Center-Line of
    the proposed dryer appliance (upward or downward exhaust direction). Relocation of
    studs may be necessary.
  3. Attach Dryerbox to studs and bottom plate with drywall screws.
  4. When installing in an exterior frame wall, you should add insulation or duct board to
    the back-side of the box to minimize condensation and temperature transfer.
  5. Gas line termination options: For black iron pipe, wrap vinyl tape around throat where
    it penetrates. For corrugated stainless steel tubing, secure the CSST Termination
    Fitting with a Jamb nut to securely affix the termination to the receptacle. The gas port
    can be enlarged or relocated easily with a step bit.
  6. To achieve a fire resistance rating (one-hour F & T) min. 2X6 wood or metal framing
    is required. The Dryerbox unit must be installed in accordance with the UL Cabinet
    System listing. An extra layer of type-X drywall must be installed in the ID of the stud
    cavity in which the Dryerbox is located. Drywall must be attached to nailers (minimum
    1” X 2”) located on the inside of the cavity wall studs. Secure nailers to wall framing at
    max 18 in. OC. The screws used to attach the inner layer of drywall shall be spaced a
    maximum of 18 inches apart. For metal studs, mineral wool (min density 4 pcf) must
    fill the entire Dryerbox wall cavity and minimum R13 Fiberglass insulation in adjacent
    cells. For wood studs, mineral wool or R19 Fiberglass insulation must fill the Dryerbox
    cavity. Visit for more detail.
  7. The new Duct Support Tab (Diagram C) will assist in maintaining the ideal penetration
    length of the 4" Snaplock rigid conduit of 2 inches. Create a "hook" by bending the
    tab at the weakened or scored locations. Break-away when duct is fully supported
    in-place. Seal penetration with foil tape or sealant caulk.
  8. Use a Roto-zip-bit router tool to cut the drywall leaving a caulk joint for the painter
    (Diagram E). It is best to caulk or mud this void (Diagram D).
  9. The baseboard is best terminated with a tapered back-cut into the rim extension on
    either side of box (Diagram E).
  10. Exposed metal can be left unpainted or can be sprayed with an acrylic latex or oilbased
    (alkyd) paint when the rest of the wall, trim or baseboard is painted.

* For a stacked dryer over washer, review dryer’s specifications to determine the height
of the exhaust port. For upward venting locate the bottom of Dryerbox 1 inch below the
bottom of the exhaust port, and or downward venting, locate the top of the Dryerbox 1
inch above the dryer’s exhaust port.
