Butt Connectors
Bad splices cause heat, voltage drop and comebacks. Kimball Midwest's butt connectors let you match the fix to the run: bare or nylon insulated for everyday crimp work, step-down and Maxi-Link for mixed gauges or 2-to-1, heat shrink or grease-filled for wet, corrosive spots and crimp-free push-in or twist-on when you need it done fast.
