I made a mistake - don't want to do it again - help

I'm surprised this hasn't fallen, guess there is no wind there?
hardware directly into ACM will pull out / tear the ACM material

you need a full-frame, 4-sided, especially for this size.
depending on your available tools and abilities, you can weld or bolt together the frame.
We use metal, it's more as it is readily available for us. Aluminum is also a good frame material

NEVER hang a sign with J hooks, they will "unhook"
you want an enclosed and secured hardware connection point

Take the sign down ASAP!!, before it gets too damaged or hurts someone, make the frame and re-install once correctly done.

 

Even with a frame it will tug and pull on that thin wood

 

Hanging signs should be heavy enough that the wind doesn't blow them around too easily. Which also means they need to be solid with heavy fasteners.
For now the wall mount is your best option

 

Possibly 10mm alumalite, bit if for whatever reason, it let go...... I wouldn't wanna be responsiresponsible for decapitating people. A sign that size should be mounted directly to a wall or some sorta solid framework which is completely stationary. You can't have something that size blowing in the wind (Peter, Paul and Mary).... especially on chains, yet. Good this happened, cause if anyone saw it from codes, you'd be cited immediately.

 

So, you're saying they Okayed this installation ?? To be better than the others, evidently don't base it on what ya see around town. Use this place for a sounding board, if you're not sure.

 

Just a friendly reminder...

m = metre
mm = millimetre
mil = 1/1000 inch

 

Had similar experience before. Welded 1/2" angle frame, drilled and bolted to welded frame using flatbat to "pinch" substrate to frame. That was about 3 years ago and still holding up. We live and learn. Just my $.02.

 

I don't hang anything with multiply chain links as it adds to "swing". Top loop, bar with two holes, and bottom loop. All connections closed.

 

SV Signworks, I'm still new also and I agree this site is excellent. I would also mount to the wall. You could blame it on the codes...regardless of if they are going to approve it, if the code book states it, then you can blame it on the codes. I also make mistakes and it sucks. Thank God for this site!!

 

Never let the customer dictate to you what they want, you tell them what they need.
