Sea-Dog Fishing Rod Holders: Side, Flush & Rail Mount
Sea-Dog fishing rod holders can attach to a flat wall, fit into a deck cutout or clamp around a boat rail. These four models serve different mounting locations and rod diameters. Compare the original Sea-Dog part number and mounting dimensions before ordering a replacement or planning an installation.
Choose a side, flush or rail mounting style
Flat-surface holder · 325121-1
White molded polypropylene with an integral standoff on the back. Mounts to a suitable flat surface using two #10 round-head fasteners.
Recessed 30° holder · 325175-1
Formed 316 stainless steel with a PVC cap and full-length PE liner. The angled, flush-mount arrangement needs a suitable deck or gunwale opening.
White rail clamp · 327161-1
Polypropylene holder for 7/8- to 1-inch diameter round rail, with a front adjustment screw for positioning the holder.
316 stainless rail clamp · 327175-1
Formed and cast stainless construction for the same listed round-rail range. Has a smaller rod opening than the white polypropylene rail version.
Rod openings and mounting dimensions
| MPN | Mounting | Material | Maximum rod diameter | Mounting surface / rail |
|---|---|---|---|---|
| 325121-1 | Side mount | White polypropylene | 1-3/4 in | Flat mounting surface |
| 325175-1 | 30° flush mount | Formed 316 stainless | 1-1/2 in | Deck or gunwale cutout |
| 327161-1 | Rail mount | White polypropylene | 1-3/4 in | 7/8–1 in diameter rail |
| 327175-1 | Adjustable rail mount | Formed/cast 316 stainless | 1-11/16 in | 7/8–1 in diameter rail |
Measure before replacing: rod diameter, rail diameter and the actual mounting pattern are independent dimensions. Similar-looking holders are not automatically interchangeable.
Before cutting or drilling the boat
- For side mounting, locate a suitably reinforced flat surface and allow clearance for the rod. The 325121-1 uses two #10 round-head fasteners, sold separately.
- For the 325175-1 flush holder, check the installation angle, under-deck clearance, drainage and the manufacturer's exact cutout drawing. It uses three 1/4-inch flat-head fasteners, not included.
- For rail mounting, confirm the rail is round and measures 7/8 to 1 inch outside diameter. The white 327161-1 and stainless 327175-1 do not share the same maximum rod diameter.
- Check the rod and reel fit, bracket adjustment and interference with boat movement. Sea-Dog recommends using a leash for rods on rail-mounted holders.
- Use installation fasteners and backing suited to the boat and the hardware; never assume a holder is rated for towing, lifting or securing heavy cargo.
