Harken 60mm Triple Aluminum Element Block w/Swivel & Becket - 6273

The Harken 60 mm Triple Aluminum Element Block with Swivel & Becket – Model 6273 is a high-strength, versatile sailboat block designed to handle multi-line control applications with efficiency and durability. Crafted using forged aluminum sideplates and a corrosion-resistant hard-anodized finish, this block delivers excellent strength-to-weight performance for cruising and performance sailing. The triple sheave configuration allows multiple lines to run through a single, compact block — perfect for mainsheet systems, control lines, reefing setups, or other control point needs where space and mechanical advantage matter. The integrated swivel head aligns the block under load and minimizes twisting, while the becket provides a secure attachment point for tail lines or additional hardware. Designed with a composite bearing sheave for smooth rotation and long service life, this Element block combines Harken’s trusted engineering with value-oriented construction for sailors wanting quality without over-built complexity.
