This wall-mounted bin organizer pairs 12 small red bins with 3 steel rails so screws, nuts, bolts, nails, and other hardware have a fixed spot within reach. Each PP bin measures 5.4 x 4.1 x 3 inches and can also stack or sit flat on a shelf when you don't need it hung, giving you flexibility as your workspace changes. The steel rails mount to a wall or pegboard and hold the durable, reinforced bins securely without wobbling, while the front-open design makes grabbing a part quick without lifting the bin out. Label stickers are included so you can tag each bin's contents, and the whole set weighs 4.6 pounds, keeping the mounted rails light on your wall or pegboard. Built from odorless, rust-resistant PP plastic and a cold-rolled steel frame, this organizer is made for workshops, garages, and craft rooms, though it works just as well in kitchens and laundry rooms.
