Harken 57mm High Load Double Footblock – Black Magic Air (3222)
Durable, low-friction deck routing for high-load applications
The Harken 57mm High Load Double Footblock (3222) from the Black Magic® Air range is built for safely and efficiently redirecting high-load lines along the deck on performance yachts and offshore cruisers. With dual sheaves, it’s ideal for systems where multiple lines need controlled routing under heavy load—such as mainsheets, runners, or halyards.
Engineered for strength and longevity, this footblock features Hard Lube-anodised sideplates and sheaves, offering excellent UV resistance and a consistently smooth finish. Inside, Torlon® roller bearings ride on a precision centre cage, ensuring they stay separated and aligned to minimise friction during high-tension adjustments.
Designed for secure mounting with either metric or imperial flathead fasteners, the hardware remains completely hidden, preserving a clean deck layout. Whether in a racing or bluewater context, the 3222 delivers dependable, low-profile performance for your most demanding deck layouts.
