Description
4′ x 8′ ESC ASF4 Steel-Framed Aluminum Trench Box
The ESC ASF4 4′ x 8′ steel-framed aluminum trench box combines a steel frame with aluminum panels to provide a compact trench box for utility, construction, and excavation work. At 4 feet high and 8 feet long, this shield is well suited to localized excavations and other applications where a shorter, more maneuverable trench box is beneficial.
The ASF4 4×8 has a 1,909 PSF panel capacity and weighs approximately 2,820 lbs. It provides 24 inches of pipe clearance and 76 inches (6′4″) of length between the spreaders.
Manufacturer data provides maximum depth ratings of 40 feet in B-45 soil, 34 feet in C-60 soil, and 26 feet in C-80 soil, subject to the manufacturer’s tabulated data, proper system configuration, and evaluation by the project’s competent person.

Applications
The compact 4′ x 8′ configuration can be useful for a range of localized utility and excavation projects, including:
- Water and sewer utility work
- Utility service connections and tie-ins
- Spot repairs and maintenance
- Valve and utility access work
- Localized utility exposure
- Street and easement excavations
- Work in congested or space-restricted jobsites
Actual suitability depends on excavation conditions and the dimensions of the pipe, structure, utility component, and equipment being installed or serviced. Always verify the required working clearance and protective-system configuration before use.
Steel-Framed Aluminum Construction
The ESC ASF4 series combines an aluminum shield with a steel frame. This design provides an alternative to conventional all-steel trench boxes for contractors looking for a trench shield suited to the requirements of the excavation and available handling equipment.
The 4×8 configuration weighs approximately 2,820 lbs, making equipment weight an important consideration when selecting, transporting, positioning, and removing the shield.
Safety and Proper Use
Trench shields must be selected and used in accordance with the manufacturer’s current tabulated data and all applicable OSHA, state, and local excavation-safety requirements. A competent person must evaluate soil conditions, excavation depth, surcharge loads, groundwater, adjacent structures, equipment configuration, and changing jobsite conditions.
The maximum depth ratings shown above should not be used by themselves to determine whether this shield is appropriate for a particular excavation. Refer to the applicable ESC tabulated data for complete requirements, limitations, and allowable configurations.
