Under Garage Door Exhaust Vent

Vent your shop. Keep the door closed.

Running a CO2 laser, resin printer, or any fume-producing equipment in the garage means one bad choice: drill a permanent hole through your wall, or leave the garage door cracked and let in the weather, the bugs, and anyone walking by.

The Summit Under Garage Door Exhaust Vent gives you a third option. It sits in the gap beneath your closed garage door and routes fumes and hot air straight outside — no drilling, no permanent modification, no compromise. When you're done, pull it out and your door seals like nothing was ever there. Renter-friendly by design.

Two widths — pick your airflow. The vent comes in two sizes so you can match it to your setup:

10″ wide — the standard vent. Ideal for CO2 lasers, 3D and resin printers, soldering, airbrushing, and most shop tools.

12.5″ wide — a larger vent face that moves more air with less backpressure. Built for high-CFM inline fans, portable AC units, and heavier dust-collection or fume loads.

Both versions share the same 6″ vent port and accept every included hose adapter, so the only difference is how much air moves through. If you're not sure, go wider — the 12.5″ never hurts airflow.

Sized around standard lumber. The shroud stands 1.5″ tall — the exact thickness of a 2x4 laid flat. Set a 2x4 plank on each side of the vent to fill out the rest of the door gap, and everything sits flush at the same height so the door seals evenly across the whole span. The planks are the only thing you supply, and they're a couple dollars at any hardware store.

It ships with 3 hose adapters covering 4″, 5″, 5.9″, and 6″ ducts, so it works with nearly any exhaust hose or inline fan you already own — and any you upgrade to later. 3D printed in the USA from PETG, it shrugs off heat, solvents, and the daily abuse of a working shop. This isn't a flimsy plastic adapter — it's built to outlast the equipment you're venting.

Why makers run Summit:

Two widths available — 10″ for everyday shop tools, 12.5″ for maximum airflow

Fits 4″, 5″, 5.9″, and 6″ hoses — three included adapters mean no scrounging for fittings

No-drill installation — seats in the under-door gap, no tools, no holes, no landlord conversations

Sized to standard 2x4 lumber — the 1.5″ shroud height matches a 2x4 laid flat, so planks on either side seal flush with the door (planks not included)

Built for fume-heavy gear — CO2 lasers, resin and FDM printers, soldering stations, airbrushing, and more

Made in the USA — 3D printed in-house in Tampa Florida
