Your #1 Source For Everything Under Construction
The 4” wall series of trench boxes are the standard of the trench shielding industry. Designed by GME, these trench shields are the work horse of the industry. With the combination of narrow sidewalls, relative light weight construction and good depth ratings, these 4” trench shields can save money, time and lives. This series of trench shields are ideal for use with 30,000 to 50,000 lb. excavators.
The 4L trench box is ideal for contractors who typically excavate to depths of 12 to 15 feet. This trench shield is modeled for the smaller rubber-tired excavators / loader machines. Utilizing special light weight materials, this trench box is ideal for repair / maintenance work.
The 4L Series Trench Shield is not designed for continuous pipe laying duty. Care should be exercised when quoting this unit.
