It’s Flashback Friday! Enjoy our 2009 QwikLug® infomercial, and let us know if you saw it when it was originally used. QwikLug® easily attaches to damaged or corroded spade connectors, quickly solving the problem of a compressor with pitted or severely corroded spade terminals. We have considered the difficulty in these field installations - the lack of space around these spade terminals - and have developed a solution. Simply push the QwikLug® connector on and tighten it from the front with a Phillips screwdriver. QwikLug® comes with color coded leads for connecting to existing wiring (Leads not included with QT2800). The outer connector housing is a nylon insulator so the connectors can touch without shorting.
