Choose your color Halyard. White, Silver, Bronze and Black
The length of halyard (rope) should be twice the height of your flagpole.
Know the diameter of your halyard when ordering. If the diameter is too big for the pulley it will fray pretty fast. 1/4", 5/16" or 3/8"
Non-wire center - recommended for any use
