The patented locking mechanism in our updated CSR2 Pulley™ is easy to release under load, creating much greater efficiency with the lowering and raising necessary to a confined space rescue. The machined aluminum swivels at both ends of the system eliminate any potential twisting of the lines. This system is also an excellent choice for confined space entry or rope access work where a heavy-duty pulley system is desired. Systems comes completed reeved and packed into its storage bag ready to use.
