Universal Valve Lockouts are easy to use, durable and lightweight. Industrial-grade steel and nylon offer impact and chemical resistance. Cable attachment is made of rustproof sheathed metal. Large levers, T-handles and other difficult controls are no problem for this versatile device. Use the Small Lockout for handle widths up to 1" with a maximum thickness of 0.6". Large Lockout Devices can effectively lockout handles up to 1.6"W with a maximum thickness of 1.1". When you add additional Adapter Arm and you can lock out three-, four-, and five-way valves, or secure the handle in the "throttled" position (for non-lockout process control). Padlocks sold separately.
