Commonly used on top or through the side of a deck pedestal, as well as through the fiberglass skin of a hardtop or T-top.\u003c\/p\u003e\n\n\u003ctable style=\"font-size:0.9em;border-collapse:collapse\"\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003eMarine Grade 6061-T6 Aluminum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003e4.5\" (114 mm)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eThickness\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003e3\/8\" (0.375\")\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eMounting Holes\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003e3 countersunk (5\/16\" dia. for 1\/4\" fasteners)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eCenter\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003e1.5\" passthrough (cable \/ hose \/ wire routing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eShape\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003eRound\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eFinish\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003eMatte — tumbled, deburred, paint\/powder coat ready\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"background-color:#1a1a1a;text-transform:none;color:#ffffff;border:1px solid #ffffff\"\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"font-weight:400;border:1px solid #ffffff\"\u003e0.5 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003cp style=\"text-transform:none;font-weight:600;font-size:1.05em;color:#4a7ab5\"\u003eCommon Applications\u003c\/p\u003e\n\u003cp style=\"font-weight:400;font-size:0.9em\"\u003eT-tops, tuna towers, hard tops, radar arches, leaning posts, grab bars, bow rails, outrigger mounts, rod holders, antenna mounts — any fiberglass or aluminum deck surface requiring flush-mount hardware with a cable\/hose routing path.\u003c\/p\u003e\n\n\u003cp style=\"text-transform:none;font-weight:600;font-size:1.05em;color:#4a7ab5\"\u003eFrequently Asked Questions\u003c\/p\u003e\n\n\u003cp style=\"font-weight:400;font-size:0.9em\"\u003e\u003cstrong\u003eWhat is the 1.5\" center passthrough used for?\u003c\/strong\u003e\u003cbr\u003eThe 1.5\" center hole lets you route cables, wiring, antenna leads, or small hoses through the pad for a cleaner finished install — no lines, wires, or hoses visible on the deck or exposed to the elements.
