The AvGo C-Lock is designed to provide lockout functionality for Klixon-style circuit breakers commonly used in aircraft and space vehicles. C-Lock is made of a flexible thermopolymer, so it can be easily installed or removed without damaging the circuit breaker or surrounding equipment, while providing adequate lockout function to prevent accidentally energizing a circuit during flight operations or maintenance activities. C-Lock can be ordered and installed with or without a coated-steel wire lanyard and our durable plastic "Remove Before Flight" tag.
