The Axxis portable restroom from PolyPortables has self-closing hinges that operate from an internal stainless steel spring, a heavy-duty rotary latch that is tough enough for rugged users, a deep ambidextrous door pull for convenience and a re-engineered door frame for structural integrity. It includes a 60-gallon waste tank, rotationally molded plastic skid, urinal, coat hook, and a three roll toilet paper holder. 800/241-7951; www.polyportables.com; Booth #2505
