Not all plastic is created equal. My tower manufacture uses Schaefer Marine
pulleys which use Delrin
sheaves. Its been up 5 years and shows no sign of wear. The tower is a 75 ft
motorized tilt over
with a 4 element SteppIR. I run the tower up and down quite often.

Subject: [TowerTalk] one more tram comment...
I forgot to mention that after seeing the deep grooves in the aluminum pulley
wheel, I shudder to
think what would have happened to the plastic sheave in the pulley I used to
tram the 40-2CD. Thanks
for the head-up on that, Eric!
