Ferno OG1 Prusik Minding Pulley
Ferno OG1 Heavy Duty Prusik Minding Pulley
The OG1 Prusik Minding Pulley from Ferno is an invaluable aid for heavy duty industrial rigging or rescue operations. It carries an impressive 36kN load rating, and a side opening plate lets you access the 51mm x 13mm sheave without disconnecting the pulley from its anchor, which speeds up rigging and re rigging on a live system. The prusik minding sheave sides are flat, so a prusik hitch is pushed open and grips the rope as a progress capture in hauling systems.
The connection point holds up to three 12mm karabiners for building mechanical advantage, and the pulley is made from high grade anodised aluminium and stainless steel for strength and corrosion resistance. It takes 11mm to 13mm rope, measures 180mm x 120mm x 47mm and weighs 950g. For a stainless twin option see the ISC prusik minding pulleys, or browse more rope access and rigging gear.

What is a prusik minding pulley?
It is a pulley with flat sheave sides so a prusik hitch on the rope is held open until it is loaded, then grips as a progress capture. That makes it ideal for hauling systems where you want the load to hold each time you reset.
Why the side opening plate?
The side plate opens so you can load or unload the 51mm sheave without disconnecting the pulley from its anchor. That saves time when rigging and re rigging a system that is already in place.
How does it compare to the ISC prusik pulleys?
The Ferno OG1 is a single heavy duty pulley rated 36kN that holds up to three 12mm karabiners at the head. The ISC prusik minding pulleys are a stainless option. Choose based on the rating and rope size you need.
