The Viper XXL is the big brother to Summit's Viper SD. This stand has all the same great features as the Viper, but offers a wider top for a little more room. The Viper XXL also comes with a Footrest for even more added comfort. This combination will certainly help make your all day sits a comfortable and enjoyable experience! Also included is another great Summit accessory, the Seat-O-the-Pants safety line with locking clip. Stand weight: 21 lbs. Capacity: 300 lbs.
