The loop slides easily through the block head and over the anchor post for a secure connection. No knots, splices, or tools required. An SK 75 DyneemaŽ loop is included with each block. Replacement loops available on request.
Tie, splice, or lash to almost anything.
A length of covered SpectraŽ line is included.
Fiber-reinforced high-strength nylon-resin sideplates have no metal fasteners for the lightest block in Harken history. Both models route the attachment line through the block head and sheave, reducing load on the sideplates and acting as a safety backup for your system.
Composite sheave spins on ball bearings with fitted races for low-friction rolling. Soft attachments reduce weight and noise while allowing the block to articulate to align with the load.
The simple construction requires no lubrication. Blocks flush clean with fresh water.
