Universal Circuit Breaker Lockout Device - up to 7/8" Tie Bar – 10 Pack

TRADESAFE universal circuit breaker lockout devices provide a compact way to secure compatible single-, double-, and triple-pole circuit breakers during electrical maintenance, repair, inspection, and servicing. This 10-pack is designed for breaker configurations with tie bar handles up to 7/8" thick, making it useful for facilities that need the same lockout device available across multiple panels, work areas, or maintenance kits.

Each device is constructed from durable nonconductive nylon with a stainless steel thumbscrew for straightforward tool-free installation. The lockout attaches directly to a compatible tie bar handle and includes two padlock shackle holes, one on each side, accepting shackles up to 5/16" in diameter. Its compact red body also provides clear visual identification when installed on an electrical panel.

Universal Circuit Breaker Lockout for Tie Bar Handles

This universal circuit breaker lockout is intended for compatible breaker configurations that use a tie bar connecting the operating handles. It can be used with qualifying single-, double-, and triple-pole breakers, provided the tie bar remains within the stated 7/8" maximum thickness and the breaker configuration allows the device to seat and tighten correctly.

Breaker design should be checked before ordering because pole count alone does not determine compatibility. Confirm that the breaker has a suitable tie bar handle and that its dimensions allow the lockout body and thumbscrew to engage securely before the device is used.

Circuit Breaker Lockout with Tool-Free Thumbscrew Installation

This circuit breaker lockout uses an integrated stainless steel thumbscrew to tighten the device onto the compatible tie bar without requiring a screwdriver or other hand tools. Once positioned correctly, the user tightens the thumbscrew, verifies that the device is firmly seated, and secures the lockout through the appropriate shackle hole with the required personal safety padlock.

Installation and construction features include:

• Integrated stainless steel thumbscrew
• Tool-free tightening
• Direct attachment to compatible tie bar handles
• Nonconductive nylon body
• Two integrated lock holes
• Accepts padlock shackles up to 5/16"
• Compact format for crowded electrical panels
• Lightweight construction for portable LOTO kits
• Red finish for easier visual recognition
• Designed for repeated electrical maintenance use

The tool-free mechanism is particularly useful when several breakers need to be isolated during scheduled maintenance because technicians do not need to carry an additional installation tool for the lockout itself. The 10-pack also allows identical devices to be distributed between electrical kits, lockout stations, service carts, or separate facility areas.

Circuit Breaker Lockout for Single-, Double-, and Triple-Pole Breakers

These circuit breaker lockout devices are suited to electricians, maintenance departments, contractors, technicians, industrial facilities, and commercial workplaces that service compatible breakers with tie bar handles. Because the same design can be used across qualifying single-, double-, and triple-pole configurations, teams can reduce the number of different breaker lockout styles they need to carry when the physical breaker dimensions fall within the supported range.

Installation begins by confirming the breaker configuration and tie bar dimensions, placing the device on the compatible handle, and tightening the thumbscrew until the lockout is firmly secured. The required LOTO padlock can then be attached through one of the two integrated shackle holes, restricting operation of the breaker until the authorized employee removes the lock at the completion of the work.

To ensure compatibility, check out our Breaker Lock Solution Guidelines to find the right TRADESAFE Breaker Lockout Device for your specific breaker model and number of poles.

Choose the TRADESAFE 10-pack when you need reusable lockout devices for compatible tie-bar circuit breakers across multiple panels or work areas. Verify the breaker configuration and the 7/8" tie bar limit before use. Keep these compact devices in electrical maintenance kits or lockout stations so they are ready when breaker isolation is required.
