Hangers and brackets are support components used in plumbing systems to suspend, support, secure, and stabilize pipe and tubing to building members and other structural elements. They are designed to support the weight of the piping, maintain proper alignment and slope (especially in drainage systems), anchor, stabilize, and accommodate expansion/contraction. Stud guards and protection plates are protective steel devices installed where pipe/tube passes framing members, like wall studs or floor joists. Their purpose is to prevent damage to plumbing systems inside the wall caused by nails, screws, or other fasteners installed during construction or finish work.
