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 Covering my Honda EB10000 October 21, 2021
Reviewer: David Montague from LA Conner, WA United Statesc GB  
Haven’t had a chance to
See how it does in bad weather but it looks like it’ll do fine.  The fit is good and the quality is fine, but mostly I have to laud your customer service.  Adam and Rob were great and right on the money with suggestions and explanations.

Great product.  Did have some difficulty putting sides on since the frame for my generator was square tubing and not round.
