They screw into my desk and act as posts, but I’m missing one of four to hold up a plank of wood, and I dont know what they’re called. I called them dowels in the accessibility image, but I dont knownif that’s correct.
Any help is appreciated.
Another image of the thing individually.
I think shelf support is my answer! They screw into a side of my cupboard, where it holds up a plank to make a shelf! Thank you!
