The 200 Series Rigging Pulleys are designed and manufactured in the UK, at ISC factory based in North Wales, where they have been crafting industry leading safety components and “Solutions in Metal” for over 50 years.  

To achieve the impressive new strength of the 200 Series Pulleys, they had to completely rethink the pulley plates from the ground up.  Using state of the art stress analysis tools, they reshaped and redistributed the material in the hot forged high-strength aluminium frames to significantly change the way they performed under load to maximize strength.  

They coupled this with a unique axle/frame interlocking design using heat treated hardened stainless steel axles which reduces the inherent tendency to deform or flex under extreme loads.  What they achieved are pulleys that are up to 150% stronger than their predecessors and are built to withstand even the toughest rigging jobs with ease.
