ISC 19mm Large Hot Forged Rigging Pulley Block

ISC's biggest block yet, the RP057 is durable, robust, and rope friendly. With a working load limit of 4000 kg (8800 lbs), this pulley is perfect for those larger rigging jobs. The ISC Large Cast Pulley is for a working line of up to 19mm and topping strop up to 29mm and is rated to 200kN. With colour coded side cheeks and pulley wheels for easy identification. A new fixed bollard dimension has been introduced to allow the user to fall in-line with rigging standard practice, whereby the topping strop should be twice the strength of the working line.
