Q-Lok Pro

*** GREY, YELLOW RED MODEL*** The Q-Lok Pro's superior design uses polycarbonate plastics, the best copper alloys, and a robust quick locking and releasing mechanism, identical to air, water and hydraulic quick connect couplings. The Q-Lok Pro mechanically locks onto the prongs of a standard plug by automatically inserting a pin / hook into the standardized 1/8" holes found on the plug prongs. When it does lock in place, there is a distinctive "Click" with a tactile feel that gives 100% confidence that all is firmly locked together. No other plug-in connector in the world does that. It is good for all indoor and outdoor extension cord use, even wet weather. Although not water-proof, it easily handles those conditions better than any other comparable device without corrosion, even in salty marine environments. We GUARANTEE 100% electricity and conductivity EVERY TIME. The Q-Lok Pro has attained the highest credibility on land and in space. It's performance and reliability is so good that NASA now uses them as standard equipment on the International Space Station (June 2013) and also purchased 400 for use in their hangers at the Space Shuttle warehouse in Florida in 2008. Tradesmen, factories, oil and gas companies even specialized industries such as Hollywood, lighting, TV and stage, Disneyland, nuclear plants, aero-space industries use them and have set a standard amongst the users as a must-have indispensable tool.
