 I think you're missing the point...it's not always about the equipment...it's about HOW it's attached to the building.... and NO ONE can phone that in.....they have to actually be there....ON SITE.

Exactly. I've seen some pretty crappy work with steel cable, forged eyebolts, unistrut, shackles, and grade-80 chain...all of which are perfectly fine to use when implemented within the scope of their intented purpose and load ratings.

Even if you purchase some sort of pre-fab and pre-approved piece of lighting "piping system" (ETC or similar) it still needs to be fastened to the structure correctly or it doesn't matter what stickers are on it.

 Hello Chuck et al..,

 Yes, if there's no rating spec available for a piece of hardware, then, definitely do NOT use the hardware.

 But, the idea or term "rated" can be misconstrued or ignored too.

Even the wire rope and fittings sold at the local "H-Depot" or "Loads" has a "rating". Usually right on the spool or package.

Remember, it's not always whether something is "rated", but, whether it is used with a proper safety margin.

 Cheers,
 Hammer

I think this thread is probably a good example of, "If you have to ask, it is time to hire a theatre rigger." This sort of job is pretty par-for-the-course and any decent rigger who has done installs should easily be able to handle it. I'm sure someone can point the OP towards a reputable local theatre rigger.

If I'm not mistaken, 1.5" schedule 40 has an OD of 2", so you guys are likely talking about the same pipe.

I think "theater pipe" is supposed to be 1.9" OD.  2" would be the rounded up version.  ?
