Its robust design surrounds valve handles to prevent accidental openings and supports multiple safety padlocks, making it ideal for professional lockout/tagout safety programs in industrial and commercial settings. ## Description Master Lock S3910 Lockout Tagout Pressurized Gas Valve Lockout fits virtually all valves up to 3 in. (76 mm) diameter and works on valves with or without guarding. This patented device surrounds the gas valve handle to protect against accidental valve opening. Accepts any Master Lock or American Lock Safety padlocks and hasps (sold separately) – multiple workers can apply their personal safety locks. Review: Seems very sturdy (only making it of metal would make it more sturdy), but it wasn't right for the purpose we bought it. If you need to lock up welding gas tanks or something large like that, I would definitely recommend this product. We needed to lock a propane tank on a barbecue grill. For that purpose, the hole was too large and the valve handle slipped out far enough to turn it. With a little modification, we made it work well enough. We didn't see that they sell the same product in a smaller size that is for 1" to 3" valve handles, which would probably have been just right for our grill. (Ooops.) If you need to lock a small tank--order that one. Review: Sirve bien y acorde al precio que lo compre en su momento que fue 245, pero ahorita que esta en mas 900, no vale la pena. ## Features - Best used for pressurized gas valve lockout applications as part of a comprehensive OSHA compliant lockout tagout safety program - Surrounds the gas valve handle to protect against accidental valve opening - Patented lockout device works on valves with or without guarding; Works with any Master Lock or American Lock safety padlock or lockout hasp (sold separately) - Valve lockout fits virtually all valves up to 3 in.
