Rail Mount Antenna Bracket — Bulk Format
The Sea-Dog Rail Mount Antenna Bracket (SED-327140) is a marine-grade mounting solution for securing a GPS or VHF antenna to your boat's rail. Built to handle the vibration, UV exposure, and moisture of everyday boating, it provides a secure, stable platform for your antenna wherever you need it on the rail.
It accepts any antenna with a standard 1"-14 thread — the universal connection used by virtually all marine VHF, GPS, and AIS antennas — making it compatible with most setups right out of the box.
This is the bulk (unboxed) version of the SED-327141-1 — identical hardware at a lower per-unit cost, ideal for marine installers and dealers stocking multiple units.

🔧 Parts Desk Insights
Best use case: The bulk format makes this the right pick for marine installers, boat dealers, and riggers fitting out multiple vessels where a straightforward rail antenna mount is needed and per-unit cost matters. It covers the same recreational boating use cases as the retail version — adding or relocating a GPS or VHF antenna on any rail-equipped boat — without the premium of retail packaging. A practical stock item for any marine service shop.
Heads up: For the full spec sheet including rail diameter compatibility and exact dimensions, refer to the Sea-Dog product datasheet for MPN 327140. If you need a single retail-boxed unit, see the SED-327141-1. For a heavy-duty lever-action laydown option for bridge clearance or trailering, step up to the Sea-Dog 316 SS Lever-Action Rail Mount Antenna Bracket (SED-327145-1). If your antenna has a 3/8"-24 thread, add the thread adapter.
