Our new Vibrant Performance HD Clamps now feature an integrated clasp mechanism with a safety lock push-button, replacing the removal quick release pin we had in the previous version. This new clasp mechanism provides an extra level of security to ensure the clamp is never unintentionally opened. By eliminating the pin in this new design, there are no longer any removeable components on the clamp, which eliminates the risk of parts being misplaced or lost. Our new HD Clamp also features a hinge spring to keep the clamp in a sprung closed position. This feature not only keeps the clamp in a closed state when installed, but also helps during installation as the clamp has been designed to naturally align and close itself onto the union sleeve. This clamp has been specifically designed to provide a positive feedback and audible click when closed, so users can rest assured that their charge system is ready to go. In addition, our newly designed HD Clamp is completely backwards compatible with any existing HD system, as it utilizes the same weld ferrules, union sleeve, and O-Rings, making it an easy replacement and upgrade from our older style HD Clamps.
