The Convertible NFPA Class II / III Harness Conversion for the 543NYC Harness allows firefighters and rescue personnel to quickly transform a compatible 543NYC Class II fire service harness into a fully functional NFPA Class III harness. Designed to expand the capabilities of the 543NYC system, this conversion component provides additional attachment points and functionality for rescue, fall protection, personal escape, and work positioning applications.
When paired with a compatible 543NYC base harness, the conversion system creates a versatile, multi-functional harness suitable for ladder operations, aerial apparatus work, personal escape systems, victim rescue, and controlled lowering operations. The design maintains excellent mobility while providing the added support and attachment options required for Class III applications.
Built for the demanding conditions of fire service and technical rescue environments, the conversion integrates seamlessly with the 543NYC harness platform, allowing users to upgrade their harness configuration in seconds. Conversion kits are sold separately from the Class II base harness and are non-returnable.
