[TowerTalk] Attaching utility box to tower face

[Gene Smar]

Dick:

     I would suggest two pieces of Unistrut steel channel across the top and 
bottom of the box, bolted to two tower legs with four u-bolts.  Just don't 
tighten the u-bolts too much and thereby kinking the legs.

Subject: [TowerTalk] Attaching utility box to tower face


I have a plastic utility box that will contain lightning arrestors and TVS
diodes for rotator control lines. I'd like to attach it to the face of my
tower (Rohn 55G).  The tower rungs are on the order of 7/16" in diameter.



I thought about using four U-bolts with ½" OD, but the only ones I've found
that small are DX Engineering saddle clamps, and I don't need that saddle (I
know they sell the hardware replacement kit, that's where I'm leaning).



Another possibility is something like a hose clamp with a stud coming out of
it, but the smallest I've found of those is ½" and that may not get small
enough.



Or perhaps a P-shaped cable clamp with rubberized contact area with the
tower rung.



I could use a couple of U- or V-bolts and attach it to a vertical tower leg,
but then it would stick out.



How have you attached a utility box to the face of your tower?
