Looking for a well-built, small pulley that has plenty of capacity and performs well- The SMC Micro PMP-s (singles and doubles) are exactly what you need. These are the smallest of three sizes of Prusik Minding Pulleys made by SMC, but don-t let their small size cause you to question their performance! These pulleys are designed and manufactured to the same high quality standards as our full-sized PMP-s.
