A few months ago, an installer told me that The Light Source Mega Clamps had some kind of rating and hence didn't require a safety cable. Now of course, personally I safety cable every piece of equipment I hang. However I wanted to know if this advice was a bunch of malarkey or if there was something to it. I know that cast iron fails catastrophically at its yield strength while aluminum deforms before failure. Aluminum is also more elastic which I presume makes it better suited for clamping to things. I think aluminum is also "stickier" when it comes to bolts coming loose over time due to vibration and temperature changes.
It was fun looking up stress/strain curves for cast iron and aluminum. Any thoughts?
And for any newbies out there who wader across this thread, just play it safe and use a safety cable. You don't wanna be responsible for someone's death.
