The C.H. HANSON 43720 is a blank octagonal aluminum metal tag designed for identification, labeling, and marking applications across mechanical, electrical, and industrial work. Each tag measures 1.5 inches in diameter and features a 0.19-inch mounting hole for easy attachment to equipment, piping, panels, or wire bundles. The aluminum construction resists corrosion and holds up in wet or high-humidity environments. Tags ship blank, allowing technicians to stamp, engrave, or mark them on-site with part numbers, valve IDs, circuit labels, or inspection dates. Each package contains 50 tags.
These blank metal tags are suited for a wide range of trade applications including HVAC unit labeling, plumbing valve identification, electrical panel circuit tagging, and pool equipment marking. The octagonal shape and uniform 1.5-inch diameter make them easy to read and consistent in appearance across large installations. They are commonly used by service technicians and contractors who need durable, permanent identification on equipment in mechanical rooms, rooftop units, or utility spaces.
Designed as a general-purpose blank identification tag suitable for use in HVAC, plumbing, electrical, and industrial applications where durable equipment labeling is required.
Tags can be attached using wire, cable ties, or fasteners through the 0.19-inch hole. Mark or stamp tags before or after attachment depending on the application. No special tools are required for attachment. Follow applicable site or facility labeling standards when identifying high-voltage panels, gas valves, or pressurized systems.
