Icon-O-Lite modular aluminum trench box system is an alternative to steel trench boxes. The system is for trench shoring, utility and communications installations and repairs, and other shallow trench work. The system is made from high-grade aluminum and comprised of modular panels, corners, vertical rails, and spreaders. The system can be assembled quickly in a 2-, 3- or 4-sided configuration by a two-man crew for rapid placement in the excavation by a small excavator or backhoe. The hollow double wall aluminum panels of the system eliminate accumulation of water, dirt and debris. The panels are available in a full range of standard sizes up to 14 feet in length with corner and vertical rails available in 4- and 6-foot heights. The tongue and groove panel design allows for quick and easy assembly as well as a secure fit keeping the panels in place.
