Brady BatteryBlock 0.94-Inch Cable Lockout
The Brady 150820 BatteryBlock offers a non-conductive post that slips through the terminal end of the battery cable to prevent it from slipping or being pulled from the device. Its low-profile design fits tight spaces, making it suitable for endline battery cables and compact assemblies. The tool emphasizes quick isolation and is explicitly designed to secure a single line in constrained areas. This option is ideal where space is limited and a straightforward lockout is needed.
Brady BatteryBlock 1.38-Inch Cable Lockout
The Brady 150821 BatteryBlock extends locking capacity with a larger profile that can secure up to six cables and lock out both inline and endline connectors. The same non-conductive post principle helps prevent accidental reconnection, while the expanded size supports more complex battery assemblies in commercial vehicles and industrial equipment. It is well-suited for environments where multiple cables must be simultaneously secured.
QWORK Lockout Plug Lockout Device (2 Pack)
QWORK offers a polypropylene lockout device designed to enclose electrical plugs and prevent accidents. This two-pack provides a non-conductive, durable solution for standard 110 to 125-volt plugs with a maximum diameter of 2 1/8 inches. Its simple enclosure design helps workers quickly isolate outlets during maintenance, reducing the risk of power restoration by mistake.
ZING 7294 Universal Lockout
ZING’s 7294 is a universal lockout device designed for multiple applications, including electrical plugs, forklifts, and gas cylinders. It fits a range of plug configurations (120V, 250V-sp, and 15-30A plugs) and accommodates forklift battery plugs and starter battery terminals. This flexibility supports OSHA standard 1910.147 lockout practices and is suitable for facilities with mixed equipment types requiring a single locking solution for various lockout scenarios.
TRADESAFE Large 220V Plug Lockout
TRADESAFE’s large 220V plug lockout is built for heavy-duty industrial use. It secures plugs with up to a 3-inch diameter and includes two cord holes at 1-inch diameter. The kit features a red lockout plug cover with a warning label and a hexagon body design, along with space for four LOTO locks. This setup supports high-energy systems and is designed to withstand tampering while ensuring clear visibility of the locked state.
TRADESAFE 220V Lockout Kit Pair
This TRADESAFE red lockout kit includes two large plug locks designed for 220V systems, with a hexagon body for easy grip and operation. It provides robust protection for multiple plugs simultaneously and is compatible with typical industrial LOTO practices. The kit is intended for facilities needing reliable, repeatable lockout across higher-voltage equipment while maintaining clear lockout labeling and access control.
Buying Guide: Key Considerations for Battery Cable Lockout Devices
When selecting a battery cable lockout device, consider compatibility with your cable diameter, connector types, and the number of cables you need to secure. Non-conductive materials help prevent accidental energization, while a low-profile or modular design improves accessibility in tight spaces. For facilities with mixed equipment, universal or multi-application lockouts offer flexibility, but ensure they can withstand expected torque and tampering. For battery-centric setups, prioritize products that securely fit terminal ends or inline configurations to avoid inadvertent loosening. Finally, verify that the selected devices align with applicable safety standards and lockout/tagout procedures in your jurisdiction.
Considerations by scenario:
- Small-bore battery cables: choose compact lockouts with posts that can slip through terminal ends for quick isolation.
- Multiple cables: opt for larger lockouts that can secure several cables or inline/endline configurations.
- High-voltage or industrial use: prioritize rugged, non-conductive materials and a design that accommodates multiple locking points and warning labels.
- Lockout visibility: ensure bold labeling and color-coding to clearly indicate “Do Not Operate” states.
- Compliance: confirm alignment with OSHA or local standards and that devices support your specific plug, battery, or connector types.
