Description
8′ x 10′ ESC ASF4 Steel-Framed Aluminum Trench Box
The ESC ASF4 8′ x 10′ steel-framed aluminum trench box combines a steel frame with aluminum panels to provide a compact trench box for utility, construction, and excavation work. Its 8-foot shield height and 10-foot length make it particularly useful for localized utility excavations where substantial shield height is needed but a longer trench box would be unnecessarily difficult to position.
The ASF4 8×10 has a 1,389 PSF panel capacity and weighs approximately 4,360 lbs. It provides 48 inches of pipe clearance and 100 inches (8′4″) of length between the spreaders.
Manufacturer data provides maximum depth ratings of 35 feet in B-45 soil, 27 feet in C-60 soil, and 21 feet in C-80 soil, subject to the manufacturer’s tabulated data, proper shield configuration, and evaluation by the project’s competent person.

Applications
The 8′ x 10′ ASF4 is a compact shield that can be considered for localized utility excavations where an 8-foot shield height is needed but a longer trench box would be unnecessarily difficult to position. Potential applications include:
- Precast manhole installation
- Valve and meter vault installation
- Utility tie-ins, tees, crosses, and service connections
- Bore pits and receiving pits
- Spot repairs to water, sewer, gas, electrical, and telecommunications lines
- Localized utility exposure and maintenance
- Utility work in streets, easements, and congested jobsites
The ASF4 8×10 is a standard trench shield and should not be assumed to be a purpose-built manhole box. Suitability depends on the actual excavation and the dimensions of the pipe, structure, utility component, and equipment involved. Contractors should verify required working clearances and the manufacturer’s allowable configuration before use.
Steel-Framed Aluminum Construction
The ESC ASF4 series combines aluminum panels with a steel frame, providing contractors with an alternative to conventional all-steel trench shields. At approximately 4,360 lbs, the 8×10 provides an 8-foot shield height while maintaining a relatively compact 10-foot overall length. Contractors should verify that the equipment used to transport, install, reposition, and remove the shield has adequate lifting capacity at the required operating radius.
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.
