The PSL-8 Non-Conductive Safety Lockout Padlocks in the standard version are keyed differently, so each padlock is supplied with one key. However, these locks can be master keyed or keyed alike. The non-conductive lock body and shackle protect against electrical hazards. The key-retention feature means that the key cannot be removed from the padlock when open. Custom engraving available. Arm material: Steel. Body material: Aluminum. Shackle diameter 0.26" (6.5 mm). Color Red. 1 per package.
