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. 

D12 Max 99 is manufactured using bio-based Dyneema SK99 for guaranteed quality, very high strength and minimal creep. For very high-load, diameter or safety critical applications, D12 MAX is the only choice, stiffer than standard D12, D12 MAX is taken to the limit of its physical properties during our "Max" manufacture process, resulting in a rope unrivaled in strength and low elongation. 

The HowNOT2 Fid Splicing Tool is an accessory for rope enthusiasts, arborists, craftsmen, climbers, professionals, sailors, and recreationalists seeking to make rope splicing simple. Crafted to make the art of splicing woven Dyneema an easy yet efficient way to join ropes. Rope splicing is the best way to integrate aesthetics with strength. This tubular rope splicing tool has a recurved internal hook to hold your feed strand in place as you thread that needle. There isn't a better price for the quality you get.
