Profile: G & H Industries designs and manufactures audio connectors. Our connectors feature Copper Core™ technology. Instrument and speaker cables are made with Show Savers™ connectors. In our BigFoot™ series, the stable design and construction of our three-conductor phone plug eliminates the need for an additional insulator over the ground tab, thus making soldering easier. MegaFoot™ has a large barrel and an oversized strain relief specifically designed to stand up to the weight of 10 and 12 gauge speaker wire without breaking.
