Description

The Harken Element 45mm Triple Swivel Block is a heavy-duty marine pulley designed for reliable rope handling and high-load sailing applications. Featuring three sheaves and a versatile swivel attachment, this block provides efficient rope routing and flexibility for demanding boat rigging systems.

Part of Harken’s Element range, it combines forged aluminum side plates with a durable, fibre-reinforced composite sheave. Its robust plain-bearing design is particularly suited to applications involving high static loads, making it an excellent choice for cruising yachts and mainsheet systems.

The multifunctional headpost allows the shackle to be locked in either direction or left to swivel freely, helping the block align with different rigging configurations.
