Sea-Dog 316 SS Lever-Action Rail Mount Antenna Bracket – 7/8" to 1" | SED-327145-1

Heavy-Duty 316 Stainless Rail Antenna Bracket with Lever-Action Laydown Handle

The Sea-Dog 316 Stainless Steel Lever-Action Rail Mount Antenna Bracket is the premium choice for boaters who want a rock-solid, corrosion-proof antenna mount on their rail — with the added convenience of a lever-action laydown handle that lets you fold the antenna down in seconds for low-clearance bridges, covered slips, or trailering.

Investment cast from marine-grade 316 stainless steel, this bracket is built to outlast painted or nylon alternatives in the harshest saltwater environments. It clamps securely to any 7/8" or 1" vertical or horizontal rail and accepts any antenna with a standard 1"-14 thread — the universal connection used by virtually all marine VHF, GPS, and AIS antennas.

At 4-5/8" wide and 3-7/16" tall, it provides a stable, low-profile platform that keeps your antenna secure at speed without flex or rattle.

🔧 Parts Desk Insights

Best use case: This is the top pick for offshore and coastal powerboats, sportfishers, and serious cruisers where a permanent, heavy-duty rail antenna mount is needed and the lever-action laydown is a genuine operational requirement — not just a convenience. Boaters who regularly transit bridges, use covered slips, or trailer their vessel will get the most value from the fold-down handle. The 316 SS construction makes it the right call for any vessel spending significant time in saltwater or exposed coastal conditions where nylon or painted brackets would degrade.

Heads up: If budget is a consideration and the laydown feature isn't needed, the Sea-Dog Nylon Rail Mount Antenna Bracket (SED-327148-1) fits the same 7/8"–1" rails at a lower price point. If your antenna has a 3/8"-24 thread instead of the standard 1"-14, add the thread adapter. Need more height above the rail? A 12" or 24" stainless extension pairs cleanly with this bracket.
