Master Lock S442 Lockout Hasp

The Master Lock S442 Lockout Hasp is a non-conductive plastic safety hasp designed for group lockout applications, particularly where small isolation points or electrical panel enclosures need to be secured. Its sliding hasp design allows up to four workers to apply their own personal padlocks at a single lockout point, helping support safer maintenance and servicing procedures.

Made from highly durable non-conductive plastic, the S442 is well suited to electrical lockout work where metal components may be less suitable. It features a thinner 3mm diameter plastic shackle, a red body for better visibility, and operating temperatures from -10°C to 50°C.
