I am working on installing wall-mounted shelves in my garage. To keep the shelves high enough that I don’t bang my head on them, I am finding I have to anchor the mounting plate up high on the wall, near the ceiling.
After installing one, I realized I am anchoring the top lag screw into the wall top plate.
The bottom lag screw in each mounting is low enough to be secured into a wall stud.
My head is screaming at me that it’s not OK to mount into the top plate but wanted to post to find out for certain. This is an exterior wall so I’d imagine load bearing?
Additional info that may be helpful: This appears to be a double 2x4 top plate (see pic, the bottom 2x4 is seen in its entirety, with the 1.5” side facing the camera). There are engineered joists above, running perpendicular to the top plate into which the shelf mounting plates are secured. I’ve added a picture of the loading limit from the installation instructions. Circled in purple is the configuration I intend to use.
