A 33-inch steel lower mast extension rated to 900 lb for confined-space davit systems

  • Product colorGreen, Silver

  • Supports 900 lb anchorage point rating
  • Meets OSHA and ANSI safety standards
  • Powder-coated steel resists corrosion
  • Compatible with offset davit mast systems

Confined Space Lower Mast Extension

The DBI/SALA 8518002 Advanced Lower Mast Extension serves as a compatible component for confined space davit systems. It connects to an upper arm mast and davit base to create a vertical entry anchorage point. This steel extension is designed for workers accessing confined spaces requiring a rated fall arrest attachment.

Sustained load behaviour

The extension carries an anchorage point rating of 900 lb tensile strength under OSHA and ANSI standards. Its powder-coated steel construction maintains structural integrity during prolonged fall arrest events or extended work positioning. The 33 in height positions the attachment point for vertical entry scenarios without compromising the rated capacity.

Practical limits of the standard

The 900 lb rating defines the maximum force the anchorage can withstand per the referenced standards. This component is restricted to use with confined space offset davit masts and cannot function as a standalone anchorage. Buyers needing horizontal entry configurations or higher capacity ratings cannot use this lower mast extension for those applications.

Questions about this item

How much heat or noise does the 33 in steel lower mast extension generate during continuous all-day use?

The 33 in powder-coated steel lower mast extension has no moving parts, motors or electronics, so it produces no heat and makes no noise during extended operation.

What existing components must I already own for the 8518002 lower mast extension to function?

The 8518002 lower mast extension requires a compatible upper arm mast and a davit base from the 3M DBI-SALA Advanced confined-space davit system to create a complete anchorage.

Will the 900 lb rated lower mast extension work with older davit bases I already have on site?

The lower mast extension is designed for use with 3M DBI-SALA Advanced confined-space offset davit masts; compatibility with other davit bases is not confirmed by the manufacturer.
