Master Lock transparent switch cover for LOTO safety. Fits push button & rotary switches (22.5-30.5mm). Self-adhesive base.
The Master Lock No. S2151 Removable Push Button and Rotary Switch Cover is designed to enhance workplace safety by prohibiting unauthorised access to critical switches or controls. Its strong, transparent ABS body allows for clear visibility of underlying nameplates and labels, ensuring equipment can be identified even when secured. This versatility makes it a key component in lockout/tagout (LOTO) procedures, helping to prevent accidental machine start-ups during maintenance or servicing.
