Description
8′ x 24′ ESC ASF4 Steel-Framed Aluminum Trench Box
The ESC ASF4 8′ x 24′ steel-framed aluminum trench box combines a steel frame with aluminum panels to provide a long trench shield for utility, construction, and excavation work. Its 8-foot shield height and 24-foot length provide an extended protected working area for underground utility and infrastructure projects where a long shield configuration is appropriate.
The ASF4 8×24 has a 246 PSF panel capacity and weighs approximately 8,300 lbs. It provides 48 inches of pipe clearance and 264 inches (22′4″) of length between the spreaders.
Manufacturer product data lists maximum depth ratings of 8 feet in B-45 soil, 7 feet in C-60 soil, and 6 feet in C-80 soil, subject to the manufacturer’s current tabulated data, proper shield configuration, and evaluation by the project’s competent person.

Applications
The 8′ x 24′ ASF4 provides a long protected work area for underground utility and infrastructure excavations where substantial working length is required. Potential applications include:
- Water and sewer utility construction
- Underground pipe installation
- Pipe repair and replacement
- Utility main installation and rehabilitation
- Utility tie-ins and service connections
- Street and easement excavations
- General underground utility and infrastructure construction
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 shield 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 8,300 lbs, the 8×24 provides an 8-foot shield height and 24-foot overall length while retaining the steel-framed aluminum construction of the ASF4 series. 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.
