[TowerTalk] hazer pulley specs?

[WW3S]

Anyone know the specs of the heavy duty pulley that goes on the top of the 
tower for a Hazer?Called Glen Martin, and they couldn't (or wouldn't) tell 
me....the last time I put it up, I bought the heavy duty pulley, and I think 
bought the stronger cable, 5/32....I have a guy coming to do some tower 
work,and want to have a spare just in case I need it....it appears as if the 
cable came off the pulley, and is jammed between the side of the pulley 
itself and its mount....
