I am using this pulley to suspend a counter weight for an amateur radio antenna across my yard. It allows the antenna wire the flex and bow as needed when the wind blows or snow collects on it. This pulley has worked flawlessly throughout the winter. High winds and icing didn’t seem to effect its effectiveness.

I included pictures for you to see it’s true size and weight. When I bought it the description was incorrect on weigh and size so I had to return it. Hopefully that’s been corrected but check pictures to see correct size and weight.It is a very small sailing block, about the size of a quarter.

I replaced the pulleys on my boat's outriggers with these. What a difference from what I had before. Sure, they are a little more expensive -- but my crew and I love them. Try these with non-stretch outrigger cord, and you'll never go back to those "industry leaders" you were using.
