Hanging canopy HELP

[Scubapro13]

Not sure if what I have is strong enough to hang. Set up is all of 70lbs if not more. This is what I bought

I plan on using a toggle blocked inbtween joist. More concerned on cable and the aluminum piece attached to canopy

Looks good and sturdy. My only advice is he careful with that cable and the tightening of the screw in this picture

if you overtighten it, itll cut the cable and down comes the light....I may or may not have experienced this before I ended up using the fittings but replacing the cable with more heavy duty cable

So you think the cables/toggle will hold it up without crashing on my tank?

It's really hard to say since the kit you're using isnt intended for what you're doing with it, but in theory yes it should work
