AudioQuest's SureGrip Spade is designed to stay in place better than your 'garden-variety' spade, thanks to a clever design which helps it fit snugly.
SureGrip accepts wire up to 9 AWG, and you can choose gold or silver plating. Red, black, and green identification labels are included with each set. Installation requires an Allen wrench, which comes with each package of four. |
