Simply unfold and lock the legs in place, install a Wag Bag and the Pett is ready for use. Made of durable injection molded plastic, the PETT toilet is the same height and bowl size of a standard toilet, yet folds to a mere 5" x 19" x 14". Weight limit tested by supporting the front end of a truck on 2 PETT toilets. The drip edge under the seat keeps the top of the waste collection bag clean for easy disposal. Each PETT toilet comes with a removable mesh net holder that supports the waste collection bag, a removable lid for stability on soft terrain when in use and to protect the seat when not in use. Included free, are 3 WAG BAG Toilet in a Bag waste kits.
