CompX M5-0687-160-390, Key, Disc Tumbler Locks, Cut Key #390

Very good shelf comes nicely sanded ready to finish. Shelf brackets are designed to screw into studs behind the wall, and can be placed anywhere along the shelf to accomodate the location of the studs. Installation was easy, I think the shelves are adequately strong for about 30 lbs. The instructions say 15 lbs per foot, but for all lengths there are only 2 brackets, do not think that the longer shelves have more holding capacity. I believe these shelves are the same shelves that some custom cabinet makers sell you for kitchen rehab, but much more expensive if you buy from them, but they match the finish.
