Made of high quality ASA to weather the outdoor elements and hot output exhausts of portable ac units in the southern heat, these vents are built to last.
Our Under the Garage Door Narrow Venting solution is used by many for cooling down their garages, exhausting the smoke from their lasers, and so many other uses when drilling a hole is not an option!
Designed to be as narrow as possible while still allowing plenty of air flow for high intake or output appliances. The same height of an industry standard 2×4 at 1.5″, it’s the perfect size to help keep within HOA regulations.
Can be painted to match your exterior.

Have an amazing workspace, extra garage or HOA Rules you have to work around, and needing a way to vent your laser, portable ac or other appliances to the outside without drilling a massive hole in the wall?
IF PURCHASING TO USE WITH A PORTABLE AC, YOUโLL WANT TO ALSO INCLUDE THE EXTENDED WINGS ADD-ON FOR MORE AIR FLOW.
The Narrow Vent duct converts a 4in, 5in or 6in standard hvac hose to the outside under your existing garage door or window by creating a flat bottom and spreading a circle airflow into a longer narrow wedge of air.
IMPORTANT: If purchasing for a Portable AC Unit, and the unit states a 5.9โณ hose size, we have an option for a 5.9โณ Hose during checkout.
All versions come standard for a 6โณ ID (Inner Diameter) hvac hose. The Vent is built in a modular configuration to allow for growth/changes.
INCLUDES HOSE CLAMP(S) & BUG/CRITTER FILTER!
We also have the option for EcoFlow Hose Adapters (Ends) for quick disconnect of the Ecoflow Wave Units. Includes both the 5โณ & 6โณ ends.
MATERIAL TYPE
Our Vents are made of ASA material which handles the high temps of portable AC units and the demanding temps of Texas & Vegas!
Measures 10.5โณ in width (Extended Version measures 21โณ in width)
1.5โณ Tall in the front to align with a 2ร4 for thickness.
10.5โณ in depth front the front to the back
You can also mix/match the wings to create a half size in width if needed. Itโs a very modular system for many uses.
Tip: Most garage doors have a disconnect from the motor which allows free motion by hand. For Temp installs, this will make closing the garage door on the boards/ducting easier. If more of a permeant install, keeping the motor engaged will help prevent easy outside lifting of the door.
This Vent is designed to be used with a standard 2×4 board from your local lumber yard such as Lowes or Home Depot when used under a garage door. This helps prevent the weight of a heavy garage door from putting too much pressure on the vent.

Turn our Vent upside down, and it works great in windows also.
