Harken Midrange Double Sailing Block, 76mm

The Harken Midrange Double Sailing Block, 76mm is built for the higher loads found on medium and large offshore sailboats. Its robust construction and double-sheave arrangement support demanding running-rigging systems where reliable line handling and efficient trimming are required over repeated sailing cycles.

The sheaves run entirely on a ball-bearing system for fast trim and release under load. With a 76mm sheave, support for line up to 14mm, and a stated maximum working load of 1,270kg or 2,800 pounds, the block is intended for appropriately engineered offshore rigging applications.

Confirm line diameter, maximum working load, attachment hardware, purchase geometry, and mounting-point strength before installation. Do not exceed Harken's published load rating, and account for dynamic sailing loads when sizing the complete system. Inspect sheaves, bearings, sideplates, attachment points, and line regularly for wear or deformation.

• Robust construction suits medium and large sailboat rigging systems.
• Ball-bearing sheaves support fast line movement.
• The block accepts line up to the published maximum diameter.
• Published capacity helps properly size the complete rigging system.
