[TowerTalk] Turnbuckles with Rod Sides

[Byron]

Thanks for replies-
    I apologize for not measuring the rods before posting. I just glanced at the turnbuckles when I was over at my friends. I called and had him  caliper one of the side rods and it measures 0.635” OD. 
    These turnbuckles are all one-piece forged – if you can envision a large, tapered, round piece at each end, threaded for ¾” x 9” long eye-bolt  pieces – large enough that a pair of  0.635” rods are forged to its underside, side by side, with ample room inbetween the rods for the ¾” threaded eye-bolt pieces. 
   I could not find a picture of these anywhere on the net. The eyes on each end are circular, forged and look like the Chicago built ones. In essence these just have rods versus a rectangular piece for the “sides”.
   These turnbuckles are tightened in conventional manner by placing flat bar inbetween rods and turning, just like you would do on the ones that have the rectangular slats for sides. The rods, being 5/8” OD, are sufficiently stiff enough for this style tightening. The threaded ends are round with no wrench flats.
  I saw some of these years ago at an OT’s residence that in years past had substantial towers (150’ to 175’) up using them. I was always curious about them and now that a friend has offered me some NOS ones I thought I would ask. I believe these were made years before the flood of the cheaper grade ones you see now. The galvanizing on them is still in great shape. I just can’t find any markings on them other than the “3/4”. Just thought I would ask, thanks, Byron W5FH
