The Rapidloo standard portable restroom from T blustar is composed of a modular interlocking system that can be assembled and unassembled using no tools or rivets and stored or transported as neatly stacked individual parts. The lightweight components can be disassembled and stacked on a trailer for easy maneuverability. If parts are damaged, simply unlock the broken part and replace it with a new part in less than a minute. Units are designed to fit three unassembled units inside of one assembled unit, allowing PROs to efficiently store or transport four times the units in one trip. Units can be assembled and disassembled in less than two minutes. 404-719-0715; www.tblustar.com.
