[TowerTalk] TH-7 10M Dire

[Daniel Hileman]

Hi Everyone, 
I am missing one part of my TH-7 10M Director...I see that DX-engineering/Texas Towers has the tubing parts, but the size is what I am not sure of. The TH-7 manual says it's 53" of 7/8" tubing for D1 and 43.5" of 7/16" for D2, but dx-engineering/TX-twrs uses decimal points not fractions...so, anyone know which one would be equivilent and is the manual talking about O.D, or Wall or what? Probably O.D. 

Thanks,
