Mainstream Engineering - Tightens quickly from the front with a Phillips head screwdriver. Has a durable brass interior shielded by nylon exterior to prevent shorting.
Most technicians have encountered the problem of a compressor with pitted or severely corroded spade terminals. The start-up current surge of repeated hot summer cycling eventually destroys the spade connector, sometimes leaving nothing but a corroded round post.
Mainstream has developed a patented product, QwikLug, to solve this problem. QwikLug easily attaches to damaged or corroded spade connectors. 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.
