Laugh all you want, there is a restaurant less than 2 miles from my house with a light duty box truss suspended with that stupid decorative stuff.... Sad  I tried to talk to the manager about it, but he didn't speak any english.

I'll bet the local building inspector speaks english well enough to issue a citation!

Hey guys, not to start up an old topic or anything but...

I am working on my first install and YES my first rig...but before you all go and tell me to hire a structural engineer to rig the speakers for me know that I ALREADY DID. I just need to buy the hardware for the SRX715(the flyable model). I will use the eye bolt but do not know where to go from there. The speakers will be hanging from a bar that is above the front edge of the stage. The bar has been tested by a structural engineer and is secure for the extra weight. I need to know where to go from the eye bolt to the bar and how to secure that to the bar.

thank you

Aircraft cable would be good. You will need cutters, crimper, and all the associated  hardware.  For a one shot deal, that can get quit expensive.

Because of liability, you will probably not get many details here.  Do some reading on standard rigging practices.

Things that can kill people are hard to get particular advice on.

It might be less expensive to hire someone to do it.

Let me start by saying don't try to do it all by yourself.  If you want to give it a shot, at least hire a rigger for an hour to come out and inspect your work to be sure it's not going to fall down.  Better yet, hire the rigger to do it and ask him to show you how it's done.

Assuming you're going to try and do it anyway, here's a rough outline of how I would go about doing it, but understand that every situation is different and I sometimes change approaches in the middle of the job if I get the feeling what I'm doing isn't going to work.  You're probably safe if you've done temporary rigging before and this is just your first time doing a permanent install, but if it's your first time EVER hanging something that could kill people above their heads at least hire a rigger to take you through the process.

from the eye bolts on the top of the speaker attach a 1/4" shackle.  to the top of the shackle you can either use aircraft cable or Grade 30 chain (for christ's sakes don't use jack chain
at the top of the chain attach another shackle
thread the shackle pin through a batten clamp
attach the batten clamp to the bar

that will get you dead hung, now you need your pull up

from the pull up point on the back of the cabinet, attach another shackle
run chain to a pull up point on the ceiling or rear wall
if going into wood thread a 1/4" wood screw through a unistrut flat plate with a lock washer and pull back to the desired angle, when you have the desired angle drive the screw through one of the links of the chain to hold it tight
if pulling up to owsj or a beam use unistrut beam clamps instead.

this is pretty rough, and based on the ceiling points being able to handle the weight, but again if you're not absolutely positive everything is going to hold then hire someone.

Oh, and carry $1-3 million worth of liability insurance, and only install once you have incorporated a company and contracted the job through that company.

Better yet, just hire a company to do it.

Please read, I AM hiring someone. Sorry is the wording was a bit confusing. I just want to get some info on here first.

Thanks for the info though,

Yeah, I read that, but I figured it couldn't hurt to put it in the message a couple times for liability reasons (in case someone else is doing something similar and just reads the post instead of asking)
