Pipe Decor 12 in. straight industrial shelf brackets come in a set of six, bringing both strength and eye-catching style to your shelves. Made with heavy-duty cast iron fittings and black steel pipe, these brackets pair beautifully with woods of various colors and sizes. They highlight your sense of style and attention to detail while fitting seamlessly into a wide range of aesthetics, including steampunk lighting, industrial, factory, French country farmhouse, vintage, retro reclamation, and DIY. You will know Pipe Decor parts and accessories when you hold them. Beauty and beast. Strength and style. This is real industrial pipe for your creative design needs—accept no substitutes. All Pipe Decor pipe and fittings are coated in a light industrial grease to prevent rusting. Clean and seal each piece before assembly to keep them rust-free, then apply polyurethane spray to protect the surface from rust and scratches. The kit includes all materials necessary to make six brackets. Each assembled bracket will hold a shelf up to 11.25 in. deep and is weight-tested to support up to 50 lbs. when mounted with anchors and screws in drywall. For maximum stability, we recommend securing the flanges into at least one wood stud when possible. The pipe is made from welded schedule 40 steel, and the final color varies from dark grey to black.
