Adjustable round valve lockout fits round valves and pipes with diameters from 1/2 inch to 4 1/4 inch. Its adaptable design covers valves and water valve lockouts with a secure, versatile solution. Industrial grade construction with a removable insert to accommodate varied handle thicknesses and an accessory to stabilize larger valves. Designed to perform reliably in extreme temperatures. Double round valve lockout supports up to six padlocks simultaneously, enabling multi person lockout coordination while maintaining clear visual identification through sturdy construction. Suitable for securing industrial lines, water supply systems, or HVAC valves in manufacturing plants, commercial buildings, or utility stations to prevent accidental activation. Key benefits: enhances safety by preventing unintended valve operation, simplifies lockout procedures, supports team lockouts with visual clarity, and maintains durability in demanding environments. Use scenarios: In a manufacturing plant, isolate a valve on a production line during maintenance by applying the lockout to all handles. On a water supply line, lock out the main shutoff with multiple technicians to coordinate a safe service window. In an HVAC system for a commercial building, secure a valve controlling a cooling tower or air handling unit during preventive maintenance.
