With your 2x4s and these engineering-plastic ShelfLinks brackets, you can assemble a custom-designed storage rack quickly...and no "angle" cutting is required! All you need is a saw (to cut 2x4s to length) and screwdriver. Each bracket holds two 2x4s vertically; then fasten four horizontal 2x4s to two brackets to create one shelf up to 8' long. Change the modular configuration whenever it suits you. Each 4'-section assembled with a pair of ShelfLinks holds up to 2000 lbs. Durable polypropylene.
