This tent uses the very same front and back as the regular pyramid tent, except we insert a strip of canvas between the front and back now making it considerably larger. For Example: a 12 ft. x 12 ft. with a 6 ft. insert now becomes 12 ft. wide x 18 ft. long. These tents are constructed with the same high quality as the rest of our tents. It has a 12″ wear strip along the ridge. Ties help hold the ridge pole in place while pitching the tent. A 12″ sod cloth is placed on ALL sides of the tent with heavy duty reinforced stake loops. This tent cannot be hung like a regular pyramid, it needs a ridge pole the length of the insert. You can use either one or two upright poles when pitching this tent. Poles not included.
