DAC-HBASE Confined Space Davit System H-Base Modular Base
The Frontline DAC-HBASE is the h-base modular base module for the Frontline DAC confined space davit system - the portable H-frame counterweight base that receives the DAC davit arm and holds the boom over the opening for entry, retrieval, and rescue.
Sold as the base only, it lets you outfit multiple work points with the correct foundation while sharing one davit arm. Matched to the DAC davit components, it conforms to OSHA 1910.146 and ANSI Z359 within the complete davit system.

The base is one part of the system. A davit base alone does nothing - it receives the DAC davit arm, which carries the retrieval system. Verify the base anchorage to the structure per the Frontline manual, and never enter a confined space without the full davit, retrieval device, harness, and a written, practiced rescue plan per OSHA 1910.146.
