Designed Specifically for 2x4 Walls

A standard 2x4 wall provides limited depth for a 4" dryer exhaust duct. To accommodate this restricted space, the Dryerbox 350 uses an oval-shaped top port measuring 4⅞" × 3⅛".

The oval opening is intentional and allows the 4" exhaust connection to fit within the shallower 2x4 wall cavity. This is an important distinction between the 350 and deeper Dryerbox models designed for 2x6 construction.

Choose the Right Dryerbox

• 2x4 wall + upward venting → Dryerbox 350 (Current)
• 2x6 wall + upward venting → Dryerbox 425
• 2x6 wall + downward venting → Dryerbox 4D
