Under Garage Door 2x4 Seal Exhaust Smoke Laser Duct Shroud 1.5in in Height

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? INCLUDES HOSE CLAMP(S)! IF PURCHASING TO USE WITH A PORTABLE AC, YOU'LL WANT TO ALSO INCLUDE THE EXTENDED WINGS ADD-ON FOR MORE AIR FLOW. This 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 5.9" Hose size, we have a 5.9 option All versions come standard for a 6" ID (Inner Diameter) hvac hose. When you choose a 4 or 5" version, we include an adapter giving you the option to change hose sizes at a later time. Everything is built in a modular configuration to allow for growth/changes. 2 versions available. A 2x4 thickness (1.5" in height) and a 2x4 Extended Version with extended Flattened section for more airflow. Assembly Instructions for the 2x4 Extended Airflow Version can be found here https://leafgreensolutions.com/assembly-instructions Works well for a temporary or permanent installation. Ducting can be spray painted to match trim for a more discrete look. Our Adapter Kit includes a 6" Base Shroud Duct along with 2 reducing adapters which convert the 6" size down to either a 5in or a 4in hose size. This kit works for those who are unsure of their hose size, or feel they may need to change hose sizes in the future. Measures 10.5" in width (Extended Version measures 21" in width) 1.5" Tall in the front to align with a 2x4 for thickness. 10.5" in depth front the front to the back We offer an option with a Front Filter to help prevent those creepy crawlies from getting into your duct if that is a concern for your area. Filters can reduce airflow a little, so it's an optional add-on. 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.
