The Bassik Negative Battery Terminal is just as the name implies, basic but with a twist! KnuKonceptz has engineered a simple design with a vast number of installation options available to the installer. The Bassik Battery Terminal uses button head screws for a low profile to fasten ring terminals of all types and gauges onto your battery! Up to 5, yes 5! (even 1/0 gauge) ring terminals can be secured using the Bassik Battery Terminal! Oh, so you prefer set screw ring terminals? Ok, it does that too! Three set screw ring terminals are easily accommodated. All these options are pleasantly hidden by the insulated color coded cover.To hold all that weight onto your battery post, KnuKonceptz has beefed up the fasteners that hold the BK-BT to your battery post. Dual cap screws are provided for additional clamping force. These screws are accessible even after the cover is in place, making installation or removal of the Bassik battery terminal simple with out making any changes to the rest of the terminal. Like all automotive battery terminals, the BK-BT is made to SAE specifications, which means that the positive and negative terminals are machined to different diameters. This is a reverse polarity safety feature so that installers can not tighten a negative terminal onto a positive battery post and cause serious damaged to vehicle electronics.
