The HaulerBiner is a mechanical advantage system, which has three pulley wheels incorporated into each carabiner, creating a compact and lightweight 6:1 or 7:1 Mechanical Advantage system.

The HaulerBiner has a purpose designed progress capture cam, with an ‘on/off’ position. It utilizes purpose-developed 6mm (1/4″) diameter rope, for strength and easy handling/best grip.
