Yes, the phenolic pulleys are the ones to use. The 15 degree reference is with regards to "off-axis" application. Picture an end view of the pulley and the cable trying to exit the groove at a 20 degree angle, and you'll get the 15 degree reference. Basically what they're trying to say is "don't misuse the pulley and try to mount it out of plane with the cable, if that makes any sense. I have four of these little phenolic pulleys raising and lowering my hangar doors, if that gives you a clue... Mark Langford m...@n56ml.com see experimental N56ML at www.N56ML.com
