Master Lock 485 – Frequently Asked Questions
1) What comes in the Master Lock 485 gate valve lockout set?
The 485 is a five-piece set covering the 480, 481, 482, 483 and 484 rotating gate valve lockouts, so one kit spans the full size range instead of buying each device individually. High-visibility permanent safety labels are included with the set, printed in English, French and Spanish, and they can be written on to name the person who applied the lockout.
2) Will a gate valve lockout work on a rising stem valve?
Yes. The center of each 480 Series lockout has a knockout that pops out to clear a rising stem, so the device still seats over the handwheel on a rising stem gate valve. Leave the knockout in place for non-rising stem valves.
3) Can I install one of these lockouts on a valve in a tight pipe run with no clearance around it?
That is what the rotating design is for. Each 480 Series lockout opens and closes by rotating outward and inward rather than needing to be dropped straight over the wheel, which is how it goes on in confined space applications where there is no room to lift a one-piece cover over the handle.
4) Can more than one worker lock out the same valve with this device?
Yes. The 485 lockouts are built for group lockout, so multiple workers can each hang their own personal safety padlock on the device and the valve stays locked until the last lock comes off. Padlocks are not part of the set, so order safety padlocks separately.
5) Are these gate valve lockouts safe to use near live electrical equipment or in a chemical plant?
The bodies are dielectric thermoplastic, so they are non-conductive, and they are made to withstand chemicals. That combination is why they get used around energized gear and in process environments where a metal lockout would be a problem.
6) How does a gate valve lockout actually stop the valve from being opened?
It surrounds the valve operating handwheel so nobody can get a grip on it to turn it, then a padlock through the device keeps it closed around the handle. It is a physical guard against accidental or unauthorized valve operation rather than a clamp on the stem.
7) Should I buy the 485 set or a single size like the 482?
Buy the set when you do not know every handwheel diameter you are covering, or when you are stocking a shop or lockout station that services mixed valve sizes. The 485 bundles all five devices, 480 through 484. If you are locking out one known valve repeatedly, a single matching size is the leaner buy.
8) How do the five sizes store without taking up a whole lockout cart?
Each size rotates into itself and then nests inside the next larger size, so all five collapse into roughly the footprint of the largest one. That is the reason facilities buying the 485 set can keep the full size range in a single safety tool box rather than a dedicated bin per size.
