FeaturesDouble cam principle provides a positive, vibration proof connectionSelf-compensating for wearNo moving contact surfaces, eliminating arcing or burning of contactsSuperior electro-mechanical connectionsLocked contacts will withstand a pulling force of 1000 lb1/3 of a turn assures a high pressure contact approaching 600 lb per sq-in, providing minimum resistanceContacts carefully machined from a high conductivity brass to a smooth sliding fit and easy locking actionWatertight elastomeric insulators molded from colorfast material, color coded for easy phase identificationRecessed contacts protected by insulating jacket that extends beyond contact ends for safetyIntegrated strain relief system features a retaining wire that prevents cable jacket pull-away and bare conductor exposurePlugs feature a high strength, molded-in-place locking ring to capture and secure the insulator to the contact
