Some background for my question:
- I have three 2x12x10 planks of stock lumber we already ran through a planer to get relatively smooth.
- They will be used for open shelving in our kitchen supported by 1/4" thick steel brackets that are rated at 200lbs per pair.
- Each shelf with have three of these brackets holding them up.
- On average, each plank weighs roughly 30lbs (rounding up for simplicity!)
- Brackets will be anchored to studs.
- However, brackets are simple "L" brackets with no "support" bar for cantilevering, hence the main reason for this question! See photo below.
- Bracket dimensions are: 11.5" deep, 9.375" tall, 1.5" wide
- Dishes, cups, and glassware can add up quick weight wise. For example, our main plates alone weigh ~25lbs.
- There are plenty of studs to anchor into if I could devise a sort of French cleat system or something similar...
Question: Is there something I could rig up along the back lip of each shelf/plank to guarantee stability/hold?
Am I over thinking this? Would adding extra support besides just brackets be overkill?
