Description Specifications Installation Guide

Take your generator outside, run it in rain or wet weather and use GenTent to avoid CO poisoning, electrocution and generator damage. GenTent withstands forecast winds up to 70mph, snow load up to 18" and rain up to 12 inches per day. This is our universal fit model for extra large (typically over 10,000W) open frame generators. Includes four frame adapters that can be used on square and round tubular frames, for panels or muffler heat shield blocking direct clamp mounts, and for extending generator frame length and width on large generators not quite large enough for the GenTent 20k. In either our TanLight or GreySkies color, GenTent provides a pleasing finished look to your portable generator. The Stormbracer Extreme Edition is UV treated, extreme cold weather rated and USA Manufactured. Simply Clamp it, Frame it and Cover it in three easy steps to Weatherproof your Power™!

4 of 5 Easy installation. Will test during next outage February 27, 2018
Reviewer: Eric Shoenthal from YORKTOWN HEIGHTS, NY United States  
[20K Std Grey] I was finally able to get around to installing my GenTent on my portable generator.  The instructions were easy to follow.  The parts seem sturdy enough but I will hold off on my final opinion until my first real life test (The only reason I didn't give five stars is that I haven't tested yet).  

The only thing I see that may be an issue is that my fill cap is under the tent so in an extended outage I will have to remove the tent to refill the gas tank.  Not a big issue but... [Hi Earl, the entire front panel (where the logo is located) is a door that'll open up tall and wide for refueling!]
