[Tower-Speak] FS: AB-577--rare complete ring of rollers

[Jan C. Robbins]

I have one very rare ring of rollers for the AB-577 military mast. 
AB-577's use two of these rings each; the mast tubes ride through and 
are steadied by them as the tubes are raised.  A ring holds four 
rollers, and is mounted to the AB-577 with four large flathead bolts. 
This ring is complete with all rollers and bolts, ready for mounting. 
It is in near-new condition, as good as you're ever likely to see 
(photos available).  $125 shipped anywhere lower 48.  Tks es 73!  Jan N0JR
