A warning label—“Danger Locked Out Do Not Remove”—enhances safety visibility during maintenance.
Key considerations
Material: Polypropylene offers impact resistance and chemical compatibility for most industrial fluids. Size flexibility is a major advantage in facilities with varied valve sizes. Availability of multiple padlock options allows multi-person authorization for critical shutoffs.
TRADESAFE Gate Valve Lockout — 2 Pack for 1″ to 2-1/2″

This two-pack set uses impact-resistant ABS plastic to secure valve handles in the off position. It accommodates valve handles from 1 inch to 2-1/2 inches in diameter and stems up to 3/4 inch. The design features an overlapping hinge and lock mechanism to reinforce a solid lockout, with one lockout padlock hole per device. Its compact form suits maintenance crews that routinely handle smaller valves and outdoor water valves, gas valves, or propane valves in industrial environments.
Practical notes
The kit’s two-piece construction and hinge ensure reliable operation, while the temperature range (-51 to 300°F) supports use in varied climates. Ensure padslocks with a 3/4 inch stem capacity are used for best fit.

Buying Guide: Key Purchase Considerations
- Valve size compatibility: Select a lockout device that covers the largest valve handle diameter in your facility, plus stems if relevant.
- Material and durability: ABS and polypropylene offer different balances of toughness and chemical resistance. Outdoor facilities may demand weatherproof and temperature-tolerant designs.
- Locking capacity: If operating with multiple authorized personnel, ensure devices provide multiple padlock holes or allow dual-lock configurations.
- Center knockout and versatility: Devices with removable center knockouts accommodate rising stem or OS&Y valves, expanding applicability across valve types.
- Ease of use: Look for overlapping hinges, simple installation, and the ability to rotate freely when locked to prevent accidental openings.
- Padlock compatibility: Check shackle diameter and hole sizing to ensure your existing padlocks fit securely; some sets include padlocks, while others require you to supply them.
- OSHA/compliance: Verify that the device meets applicable lockout/tagout standards and is appropriate for industrial environments.
- Pricing and bundles: Multi-pack options can reduce cost per device and simplify procurement for larger facilities.
In summary, selecting the right gate valve lockout device depends on valve size range, environmental conditions, and the number of authorized personnel.
