Micro pulleys can be used as a prusik minding pulley in a climbing system or tree pulling kit. The pulley advances the prusik without the need to manually advance the prusik. Micro pulleys are offered in different sizes and configurations.
The DMM Hitch Climber Pulley is the most popular pulley to add to a climbing system and is a low cost investment to increase efficiency in your climbing system.
Traditional systems using a Blake's Hitch can benefit from adding a micro pulley. With a simple kit like the Notch Micro Pulley Combo, you can remove the need to advance the prusik manually saving you time and energy.
The Camp Dryad Double Pulley is a great choice for a tree pulling kit as it is very compact and easy to handle.
