Harken AirBlock 75mm Double Swivel
Harken's 75mm Black Magic AirBlocks are used for sheeting and halyard systems, running backstays, and control lines.
They feature strong and long-lasting Torlon roller bearings housed in a center cage with sculpted hardcoat-anodized aluminum sideplates to protect the sideload ball bearings. Easily adaptable, they feature three-way, swivel heads that lock in front and side positions. The H3230 soft-attachment Loop block has a removable dead-end post for attachment to a pad eye. Lashings can also be used.
Corrosion is minimized by isolating dissimilar metals. AirBlocks can be taken apart with a single hex wrench.
