Harken 75mm Black Magic Air High Load Padeye Block
Teardrop-style precision for masthead leads, backstays, and halyard control
The Harken 75mm Black Magic Air High Load Padeye Block is a teardrop-shaped configuration engineered for high-load halyard leads, masthead sheeting systems, and permanent backstays. With a Safe Working Load (SWL) of 2268kg and a Breaking Load of 4536kg, this block is specifically optimised for applications where minimal articulation and compact, direct connection are preferred.
Teardrop Design – Fairleads Without Deck Contact
Designed for use with a compatible padeye, this block’s teardrop profile ensures it won’t strike the deck when lines are slack, yet provides just enough movement to maintain fairleads when halyards are jumped or tensioned. It's particularly well-suited for use as:
- Masthead halyard leads
- Permanent backstay terminations (especially on fractional rigs where the backstay can be spliced directly to the head of the block)
- High-load deflection points with constrained movement
Engineered for Maximum Efficiency
The 75mm sheave rotates on Torlon® roller bearings supported by a precision-machined centre cage that keeps rollers separated and aligned to reduce friction under extreme loads. Delrin® side-load ball bearings further enhance alignment stability and are fully captive for easy maintenance.
Hard Lube-Anodised for UV & Wear Resistance
Both the sheaves and side plates are Hard Lube-anodised—an advanced finish that delivers exceptional UV protection, superior resistance to abrasion, and a low-friction surface that extends the block’s performance life in harsh marine conditions.
Compact, Secure Mounting
This block is directly attachable via padeye (sold separately), creating a low-profile and secure fit ideal for permanent rigging points where maximum strength and minimal movement are required.
