Harken 45mm Triple Element Block Swivel Becket

The Harken 45mm Triple Element Block Swivel Becket gives efficient line handling for compatible sail-control systems. Element blocks use forged-aluminum sideplates with compound curves for strength while limiting metal to the areas needed to protect the sheave, creating a robust block for sheets, halyards, controls, and other appropriately loaded running-rigging applications.

Hardcoat-anodized sideplates resist corrosion, and the sheave runs on a proven journal-bearing system for dependable operation. This model's swivel, becket, cam cleat, fiddle, stand-up, double, or triple configuration should be selected according to the required purchase arrangement, lead direction, attachment method, and line-management needs.

Confirm sheave diameter, maximum line diameter, maximum working load, breaking load where specified, attachment hardware, and expected lead angle before installation. Size the complete system for the highest anticipated sailing loads, inspect attachment points and line condition regularly, and replace hardware that shows deformation, cracking, excessive wear, or corrosion.

• The block redirects or multiplies line force in compatible sail-control systems.
• Compound-curved metal construction gives strength around the sheave.
• Hardcoat-anodized sideplates protect exposed aluminum surfaces.
• Model-specific swivels, beckets, cams, and multiple sheaves support different rigging layouts.
