Constructed of heavy-duty polyester, our durable tags offer completely encapsulated graphics that withstand moisture, grease, chemicals and extreme temperatures. Tags accept pencil, pen and marker (pen and marker can be completely erased using isopropyl alcohol, allowing for repeated use!). Heavy duty construction holds up to 80 lbs of pull force, preventing accidental removal. 3/8" diameter heavy-duty brass grommet accepts most padlock shackles. Tag size is 5 1/2"H x 3"
