I have just installed these cool black iron pipe for shelf brackets on an office wall. The wall is 3/4” pine 7.5” wide. Each pipe is attached with 4 #10 screws 1.25 long.
Each board is attached to framing at the top plate and at purlins as indicated. The tape indicates where studs are.
I did not attach directly to studs because it made for odd spacing on these 98” shelves.
I have been questioned about the decision not to attach on studs over strength of shelf concerns.
Is there any reason to think these supports will be inadequate as installed?
Shelves are for books and will be 1” thick pine boards 11.5” wide. Supports are 23” on center.
Should I move the supports to the stud location?
