Peerless Electronics is now distributing the full line of Master Lock aviation safety products, including the new aircraft circuit breaker lockout/tagouts. The S2329 Master Lock aircraft circuit breaker lockout prevents accidental re-energizing of an electrical system by locking a circuit breaker in the “off” position. They assist in FAA and OSHA compliance for lockout/tagout (aircraft LOTO) systems. S2329’s universal fit accommodates long or short aircraft circuit breakers, with or without collars and with three- and six-prong power receptacles.
