874PO
This cast aluminum piece is a mast step/base casting (specifically, an oval-section mast step or mast foot (2” x 2.5”), often used in deck-stepped configurations or as part of a tabernacle/hinge system).
Material: Cast aluminum (typically marine-grade 356 aluminum with a mill or anodized finish).
Design Features: It features an oval socket collar matching a specific aluminum mast extrusion profile, a central drain/wiring hole, a slotted mounting flange for precise fore-and-aft adjustment, and aft hinge pin holes/slots designed to pivot the mast during stepping.
Common Manufacturers: Similar cast aluminum spars and hardware components were widely produced by spar makers and riggers such as Z-Spar, Famet, MetalMast, and Rig-Rite distribution lines, and used across various classic trailerable sailboats (such as certain Columbia, O'Day, Morgan, and Pearson models).
