Description
8′ x 14′ ESC ASF4 Steel-Framed Aluminum Trench Box
The ESC ASF4 8′ x 14′ steel-framed aluminum trench box combines a steel frame with aluminum panels to provide a durable trench shield for utility, construction, and excavation work. Its 8-foot shield height and 14-foot length provide additional protected working space while maintaining a more compact footprint than longer mainline trench shields.
The ASF4 8×14 has an 845 PSF panel capacity and weighs approximately 5,520 lbs. It provides 48 inches of pipe clearance and 148 inches (12′4″) of length between the spreaders.
Manufacturer data provides maximum depth ratings of 23 feet in B-45 soil, 18 feet in C-60 soil, and 15 feet in C-80 soil, subject to the manufacturer’s tabulated data, proper shield configuration, and evaluation by the project’s competent person.

8′ x 14′ ESC ASF4 Price and Spreader Configuration
The 8′ x 14′ ESC ASF4 Steel-Framed Aluminum Trench Box is priced at $19,185 and comes standard with four 36″ spreaders. This configuration provides a complete trench shield setup ready for assembly and use.
Other spreader sizes are available to accommodate different trench widths and jobsite requirements. Contact Iron Lot for available spreader options, pricing, and assistance selecting the appropriate configuration for your excavation.
Applications
The 8′ x 14′ ASF4 provides additional working length compared with the shorter ASF4 configurations and can be considered for a range of underground utility and construction excavations. Potential applications include:
- Water and sewer utility work
- Underground pipe installation
- Pipe repair and replacement
- Utility tie-ins and service connections
- Utility exposure and maintenance
- Street and easement excavations
- General underground utility 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 5,520 lbs, the 8×14 provides an 8-foot shield height and 14-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.
