Benefits
  • Reliability and safety. The pit cover is the only component permanently exposed to daily operations, so it has to perform. 4MF covers are aircraft load rated, lift with one hand, and allow rapid access to valves when needed. Every assembly is competitively priced, dependable, and backed by a warranty.
  • Installation advantage. 4MF fuel pit assemblies can be supplied as factory-built subassemblies that reduce field labor and installation variability. Controlled shop fabrication moves more of the work into a controlled environment, supporting consistent quality and smoother installation on active airfield projects.
  • Adaptable by design. Each assembly can be configured to meet project-specific requirements for pipe and valve sizes, entry type, pit size, and depth. Adjustable cover assemblies allow configuration between Lay Flat and Non-Lay Flat requirements as your specifications change.
