These are hand-made from .04” flat brass stock, sheared to size, with 24 or 48 Fast-On tabs securely soldered into place. Ships complete with installation hardware—brass bolt, nuts, internal-tooth lock washers, and spacer washers to accommodate any thickness of firewall. Most projects will require a single 24-point Ground Block on the cockpit side of the firewall; “loaded” electrical systems may require the 48-point block. A full “firewall ground kit” is also available in two sizes for composite aircraft needing ground points on both sides of the firewall.Choosing A Ground System:Most projects can do the job with a single, 24-point ground block on the cockpit side of the firewall. Many electrical accessories forward of the firewall get an electrical ground by virtue their mounting on a metallic firewall - OR - grounded through a mounting on the engine. Only projects with a very busy electrical system will need 48 grounds behind the panel.Airplanes with composite firewalls need some ground points on the forward side. The full-up firewall ground kit includes a long brass bolt with sufficient brass washers to shim between the two ground blocks on a thick, composite firewall. Single ground blocks are shipped with a shorter brass carry-through bolt, washers, and nuts for sheet metal firewalls.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eManufacturer Part #:\u003c\/strong\u003e GB24\/24\u003c\/p\u003e","brand":"Aircraft Spruce","offers":[{"title":"Default Title","offer_id":54230067904854,"sku":"07-03465","price":152.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1037\/0164\/3606\/files\/grounding_blocks_group_a6a4d0e3-cb61-4a57-abc3-3fe1bde142ab.jpg?v=1781775588","url":"https:\/\/www.aircraftpartseurope.com\/products\/07-03465","provider":"Aircraft Parts Europe","version":"1.0","type":"link"}
