The Master Lock Seal-Tight handle-on valve lockout clamps onto a ball valve handle stop and combines with a padlock (sold separately) to help protect against valve operation during maintenance and repair, and fits 1/4" to 4" (.6 cm to 10.1 cm) sized ball valves.This lockout is made from aluminum and steel parts that function in temperatures from -70 to 350 degrees F. It accommodates padlock shackles up to 9/16" outside diameter and includes three "DANGER" labels, one each in English, Spanish and French.This device is part of a lockout/tagout (LOTO) safety procedure required at facilities where electrical plugs need to be isolated during maintenance and repair.

I purchased the Master Lock Seal-Tight Handle-On Valve Lockout to lock a water shut off valve for a client. It is easy to use and works well.

seem easy to use once you figure out the specific way it is applied. There is a video for this on the Master Lock Industrial website...it is however quite hard to locate. The stem that pushes thru the small opening on the handle is quite thin. It seem to be about 3/16". So it seems quite easy to undo once the stem is broken.

Photos are deceiving this thing is very small and would not fit and lock a one inch valve. total waste of time & effort. I can make something that will work because so far all I have found is plastic or junk.

I ordered this and had to return it. It did not fit and the directions that were online were poor.
