TRULY UNIVERSAL - In order to work wherever you might need it, we designed each busbar to handle up to 300V AC, 48V DC. So whether your working on a boat, a car, or an RV, we've got you covered. YOU'RE COVERED - What's the first thing that always breaks on a busbar? The cover. They're usually thin, rigid, and brittle. Not these covers. Our covers are flexible, flame-, and aren't held on by tiny, breakable clips or easy to lose nuts. WORKS WITH YOU, NOT AGAINST YOU - Extra tall cover cutouts give you maximum flexibility with minimal effort. Use whatever gauge wire you need, route your wires from either side, double-stack wires if necessary, the covers will still fit. SIMPLE - Sometimes "more options" just means more difficult. Our power and ground 12 terminals, distribution block gives you everything you need without overcrowding your system, or your patience.
