Lower Mast Extension 33 In

The Honeywell Miller DuraHoist Lower Mast Extension extends a confined-space davit system by 33 inches. It connects to compatible upper arm masts and bases to raise the anchorage point for vertical entry operations. The component is built from aluminum and steel with a powder-coated and zinc-plated finish. It is rated for a 5,000 lb anchorage point.

Sustained Load Performance

The extension maintains its structural rating throughout the duration of a confined-space entry or rescue operation. Aluminum and steel construction resists deformation under the continuous 5,000 lb anchorage load. Powder-coated and zinc-plated surfaces protect the material from environmental exposure during extended deployments. The fixed 33-inch height provides a consistent reach without adjustable mechanisms that could settle under load.

33 Inch Fixed Height Constraint

This part adds exactly 33 inches of reach and cannot be adjusted to shorter or longer lengths. Buyers needing a different mast height must select another extension model. The component is designed solely as a lower mast extension for the DuraHoist series. It does not function as a standalone davit, upper arm, or base unit.

Questions about this item

Does the 33 in lower mast extension add noticeable weight or vibration when used all day?

The powder-coated aluminum and zinc-plated steel construction keeps weight low and vibration minimal during extended confined-space operations.

What existing components must I already own for this DH-22/33 extension to work?

It requires a compatible DuraHoist upper arm mast and a DH-3 or DH-4 davit base to form a complete anchorage system.

Will this 33 in extension fit the older MR50GB/50FT winch I still use?

Yes, the extension is listed for use with the MR50GB/50FT winch, so it connects directly to your existing confined-space davit system.
