200-Series Medium Rigging Pulley

To achieve the impressive new strength of the 200 Series Pulleys, ISC completely redesigned 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. 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. The new pulleys are up to 150% stronger than their predecessors and are built to withstand even the toughest rigging jobs with ease.  

The new Patent Pending “SafeLock” system builds upon the reliability and ease of use that our customers expect from ISC pulleys. The new SafeLock locking mechanism achieves an extremely low profile design while maintaining the quick action of a SpringLock.    

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