🔧 Parts Desk Insights
Best use case: A solid mid-range rail antenna bracket for recreational boaters adding a GPS or VHF antenna to an existing rail without needing the lever-action laydown feature of the premium SS bracket. Well suited to freshwater and protected coastal use where a straightforward, secure rail mount is all that's needed. The retail-boxed format makes it a good choice for single-vessel installs and over-the-counter sales.
Heads up: For the full spec sheet including rail diameter compatibility and exact dimensions, refer to the Sea-Dog product datasheet for MPN 327141-1. If you need a lever-action laydown handle for bridge clearance or trailering, step up to the Sea-Dog 316 SS Lever-Action Rail Mount Antenna Bracket (SED-327145-1). For a lightweight, budget-friendly option, see the Sea-Dog Nylon Rail Mount Antenna Bracket (SED-327148-1). If your antenna has a 3/8"-24 thread, add the thread adapter.
