Brady?s Labeled Lockout Hasps combine the advantages of lockout tags and safety hasps in a single convenient product. These tough, aluminum hasps accommodate group lockouts as up to 6 workers can apply their individual locks. The permanent front- and back-side labels feature the bold DANGER DO NOT OPERATE message for equipment lockout. These labels have a write-on surface that accepts pen, pencil or permanent marker. Pen and pencil markings are erasable allowing for repeated use. Lock holes accommodate standard ¼? and 9/32? shackle diameters.
