We have lab equipment monitors that ended up losing most of their hangers.
I made a custom rebar bender jig to bend the loops out then another for shaping the hooks.
Pieces of C-channel were cut to size and holes were drilled in them to match the original hanger.
All of the custom bent rebar were welded to the C-channels to replicate the other hangers that were missing.
These were mass produced on a small scale.
A total of ten were produced. Then they were all sprayed with primer and gray paint to prevent rusting.
