Brady 065396 Universal No-Hole Circuit Breaker Lockout for 277V Breakers, Red, 1 Piece

Circuit breakers without a hole in the switch tongue are difficult to lock out safely, leaving maintenance crews exposed to accidental energization. Brady's universal no-hole lockout solves this by clamping securely onto the toggle, so you can apply a padlock and comply with OSHA lockout/tagout requirements without modifying the breaker.

Who is it for

Electricians, maintenance technicians, and safety managers who need to isolate 277V circuit breakers that lack a built-in lockout hole. It fits most standard single-pole and multi-pole toggles and is ideal for industrial, commercial, and institutional electrical panels.
