Gate valve lockout for hand wheels

The Master Lock 481 is a collapsible gate valve lockout designed for handle-type hand wheels with diameters from 2 in to 5 in. It accepts up to three padlocks with shackles up to 5/16 in and fits handle thicknesses up to 1.5 in. The unit includes danger labels in English, French and Spanish.

Who this suits and who should look elsewhere

This lockout suits maintenance teams and authorised personnel who need to isolate gate valves during service work on hand wheels within the stated diameter range. It is not for buyers who need to secure valves with larger hand wheels, different operating mechanisms or padlock shackles exceeding 5/16 in.

Collapsible design with multilingual danger labels

The collapsible construction allows compact storage and straightforward placement over the valve hand wheel. Each unit is supplied with English, French and Spanish danger labels that read "Danger Do Not Operate" for clear on-site identification.

Questions about this item

How much force does the 481 need to clamp onto a 1.5 in thick hand wheel all day?

The 481 collapsible lockout clamps by hand onto hand wheels up to 1.5 in thick and holds without power or moving parts, so no sustained force or heat is generated.

What padlocks must I already own to use the 481 lockout?

You need up to three padlocks with shackles no larger than 5/16 in diameter to secure the 481 lockout through its three locking holes.

Will the 481 fit the 2 in hand wheels on my older gate valves?

Yes, the 481 adjusts down to a 2 in minimum hand wheel diameter and up to 5 in, covering the range of older valves.
