Harken 40mm Carbo Air Triple Swivel Block w/Becket

The Harken 40mm Carbo Air Triple Swivel Block with Becket is a lightweight, compact rigging solution designed for applications requiring low-friction load transfer and high working capacity. Originally engineered for marine and sailing environments, this block has proven its versatility in automotive hauling, winch systems, and recovery operations where smooth mechanical advantage and durability matter. Its triple-swivel design and becket attachment point make it ideal for users who need reliable load distribution without the weight penalty of traditional metal blocks.

Built with Harken's proprietary low-friction Carbo Air composite construction, this 40mm block delivers high working loads in a compact 3 x 1 x 5 inch footprint, weighing just 0.3 lbs. The composite material resists corrosion and weathering far better than steel, making it superior for outdoor and marine environments where salt spray or moisture exposure is common. The triple-swivel configuration allows multi-directional load angles without binding, while the integral becket provides a secure attachment point for fixed rigging or recovery anchor points—eliminating the need for additional hardware.

Vehicle recovery enthusiasts, off-road mechanics, and commercial hauling operations benefit most from this block's lightweight strength-to-weight ratio and corrosion resistance. It pairs well with synthetic rope systems and integrates seamlessly into existing winch tackle arrangements without adding significant mass to your rig. For anyone upgrading recovery gear or building a portable rigging kit, the Harken 40mm Carbo Air Triple Swivel Block delivers the reliability of marine-grade engineering at an accessible price point.
