The Rock Exotica Prusik Minding Pulley (PMP) is the original, time tested workhorse for lifting, hauling and tensioning in heavy load environments. Both the single and the double versions of the PMP boast an impressive 44kN MBS and are certified by UL to the NFPA 1983 "G" standard. True to Rock Exotica's high standard of design and production capabilitiy, the sideplates of the PMP are milled in strategic areas to reduce weight while maintaining strength. The PMP utilizes 2" sheaves with high efficiency bearings to get the most out of each pull.
