Harken 38mm Single Big Bullet Block

The Harken 38mm Single Big Bullet Block is a precision rigging component designed for vehicle recovery, winching, and load-handling applications where controlled mechanical advantage is essential. This block is built to meet the demands of off-road enthusiasts, mechanics performing vehicle extraction, and fleet operators managing heavy-duty pulley systems.

The 38mm diameter is optimized for mid-range rope diameters, specifically accommodating ropes from 5/16" to 1/2". This design reduces friction and improves line efficiency compared to smaller blocks. The single-block configuration allows for a direct 1:1 mechanical advantage when used with other blocks or as a redirect point, ensuring smooth sheave rotation and minimal binding during dynamic load management.

Ideal for mechanics, recovery professionals, and vehicle enthusiasts, this block is essential for building or maintaining winch systems, anchor-point rigs, and multi-line recovery setups. Its robust construction ensures reliability in challenging field conditions, making it a valuable tool for anyone involved in heavy-duty load management.
