Description
6′ x 6′ ESC ASF4 Steel-Framed Aluminum Trench Box
The ESC ASF4 6′ x 6′ 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 6-foot height provides additional vertical protection compared with the 4-foot-high ASF4 models, while the compact 6-foot length can make the shield easier to position in localized excavations and confined jobsites.
The ASF4 6×6 has a 3,617 PSF panel capacity and weighs approximately 2,860 lbs. It provides 36 inches of pipe clearance and 52 inches (4′4″) of length between the spreaders.
Manufacturer data provides maximum depth ratings of 40 feet in B-45 soil, 40 feet in C-60 soil, and 30 feet in C-80 soil, subject to the manufacturer’s tabulated data, proper shield configuration, and evaluation by the project’s competent person.

6′ x 6′ ESC ASF4 Price and Spreader Configuration
The 6′ x 6′ ESC ASF4 Steel-Framed Aluminum Trench Box is priced at $9,075 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 6′ x 6′ ASF4 combines a relatively compact overall length with a 6-foot shield height, making it a practical option for localized utility excavations where a longer trench shield may be unnecessary or more difficult to position. Potential applications include:
- Utility tie-ins and service connections
- Spot repairs to underground utilities
- Valve and utility component installation
- Localized water and sewer work
- Utility exposure and maintenance
- Street and easement excavations
- Confined or congested jobsites
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 2,860 lbs, the 6×6 provides a compact steel-framed aluminum configuration while still requiring appropriately rated equipment for handling, installation, repositioning, and removal.
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.
