Master Lock No. 421 Steel Lockout Hasp, 38mm Jaw, Holds 6 Padlocks
Master Lock steel lockout hasp for group safety. Holds 6 padlocks, 38mm jaw, red handle. Essential for LOTO compliance.
The Master Lock No. 421 Steel Safety Lockout Hasp is an essential device for ensuring the safety of personnel during maintenance or servicing work. Designed with a robust heavy-gauge steel jaw and a distinctive red vinyl-coated handle, it provides clear visual identification as a safety lockout device. Its primary function is to keep equipment securely inoperative by allowing multiple workers to apply their own padlocks, guaranteeing that the control system cannot be reactivated until every individual has removed their lock.
This hasp can accommodate up to six padlocks simultaneously, making it ideal for group lockout/tagout (LOTO) procedures at a single isolation point. The 1½-inch (38mm) inside jaw diameter offers ample clearance for securing onto a variety of valve handles, switches, or other control points. The bright red handle not only enhances visibility but also provides a comfortable grip during use.
Constructed from durable steel, this lockout hasp is built to withstand the rigours of industrial environments. Its compact dimensions ensure it can be easily carried and applied in confined spaces. By enforcing a strict protocol where the last worker's padlock must be removed to release the hasp, it creates a failsafe system that prevents accidental or premature re-energisation of machinery, protecting workers from hazardous energy.
