Pulleys have stainless sideplates to properly distribute loads. Delrin sheaves provide the strength, endurance and chemical resistance required by marine applications and harsh environments. This makes them ideal for antenna installations. Sheaves are designed for synthetic line like our Dacron® rope. The #166 pulley features "swivels." These are important because rope twists under tension. This can twist your antenna and this is important in some configurations. |

| I have suggested using high
quality "Sailboat" or marine quality pulleys in several of my publications.
This type pulley is precision made so that there is little space between the
sheave and sides of the pulley. Unlike hardware store pulleys, it's all but
impossible for your antenna support rope to jam the pulley by rolling off the
sheave. Since pulleys of this type are almost impossible to find in most areas of the country, I still stock one of these pulleys which is very well suited for use with the high quality antenna support rope that we sell. This pulley is manufactured by one of the preeminent makers of sailboat rigging. |
