Harken 60mm Triple Aluminum Element Block with Swivel – 6272

Description

Harken 60 mm Triple Aluminum Element Block with Swivel – 6272

Maximize mechanical advantage and streamline high-load line handling with the Harken 60 mm Triple Aluminum Element Block with Swivel (6272) — a heavy-duty, versatile sailing block engineered for demanding sheet, halyard, and tackle systems on cruising and performance sailboats. Featuring three precision-machined, 60 mm sheaves housed in a lightweight anodized aluminum body, this triple block delivers superior strength, smooth operation, and excellent corrosion resistance for long-lasting performance at sea.

The swivel head allows the block to rotate and align naturally with changing line angles under load, reducing chafe and optimizing power transfer. Each sheave rides on sealed, low-friction bearings, ensuring smooth line movement even under high tension. Ideal for multi-part purchase systems, traveler cascades, or control line setups requiring added mechanical advantage, the 6272 block provides sailors with the leverage needed to handle tough trimming and adjustment tasks with confidence.

Whether you’re rigging a powerful mainsheet system, a multi-part halyard tackle, or complex control line assemblies, this triple aluminum block with swivel adds efficiency, strength, and reliability to your sailing rig.

Key Performance Features

• Triple Sheave Design: This block features three independent 60mm sheaves, allowing you to create high-power 6:1 or 7:1 tackle systems for heavy-load applications like mainsheets.

• Hard-Anodized Aluminum: The sideplates are made from hard-anodized aluminum, which provides excellent protection against salt corrosion and physical impacts.

• Composite Bearing System: It uses a proven composite bearing that excels under high static loads. Unlike some ball-bearing blocks, these won’t “flat spot” when left under high tension for long periods.

• Versatile Swivel Head: The head can be set to rotate 360° to prevent line twists or locked in two different positions to ensure the block remains perfectly aligned with the load.

• Optimized for Modern Lines: The sheave is shaped to handle modern braided lines up to 12mm (1/2″) in diameter with minimal friction.
