Description
I wanted to use these 1 7/8" split frame pulley's on my full wave loop antenna: https://www.amazon.com/gp/product/B07NTPBYG5
The problem was that the loose fit between pulley and frame made for a possiblity that antenna wire could get trapped between the side of the pulley hub and the frame during the raising process. These inserts were designed to constrain wire movement and reduce that potential. They should be printed in a weatherproof, UV resistant material. I used PETG. Two inserts get glued to the frame sides of each pulley. I used CA glue, but any weatherproof adhesive should be OK.
ETA: I ended up using fully printed corner pulleys. These
