Round rail · 1.315 in OD · Horizontal-rail clamp
For a horizontal round rail measured at 1.315 in outside diameter
Review exact partIdentify C.E. Smith Clamp-On Rod Holders by Rail Size
Trying to identify a clamp-on fishing-rod holder removed from a boat rail? Start with the rail shape, the original tube direction and the measured outside dimension. C.E. Smith's aluminum round-rail models look similar but are made for distinct diameters, while the pontoon 55108A uses protective liners for square rails.
Identify C.E. Smith rail clamps by MPN
| MPN | Rail shape | Rail dimension | Clamp orientation | Construction |
|---|---|---|---|---|
| 53710 | Round | 1.315 in OD | Horizontal-rail clamp | Anodized aluminum |
| 53730 | Round | 1.90 in OD | Horizontal-rail clamp | Anodized aluminum |
| 53735 | Round | 1.90 in OD | Vertical-rail clamp | Anodized aluminum |
| 53740 | Round | 2.375 in OD | Horizontal-rail clamp | Anodized aluminum |
| 55108A | Square | 1 or 1¼ in | Adjustable pontoon clamp | Stainless tube; alloy clamp |
Model 53710 is the horizontal-rail holder for 1.315-inch OD. Model 53730 uses a horizontal clamp for a 1.90-inch OD rail, while 53735 matches that same diameter in a vertical-rail arrangement. The larger horizontal model is 53740, for 2.375-inch OD.
The 55108A is the distinct pontoon-style holder for 1-inch or 1¼-inch square rails. It has adjustable angles, a stainless tube, protective liners and included mounting screws with a hex key.
Measure the mounting rail itself. For the round-rail models, C.E. Smith specifies the outside diameter (OD), not the tube's nominal pipe size. Match horizontal versus vertical rail orientation as well as diameter. The 55108A is made for square pontoon rails, not a round tube with a similar measurement.
Inspect the original installation
- Find the full number. Check for a C.E. Smith MPN on the holder, its packaging or prior records.
- Identify the rail section. A horizontal-rail clamp is different from one intended for a vertical rail, even if the rod-holder tube looks similar.
- Measure rail outside diameter. For the round models compare 1.315, 1.90 or 2.375 inches; for 55108A measure the width of the square pontoon rail.
- Look for liners and adjusters. The 55108A uses two protective sleeves for its specified square rails. Missing sleeves or hardware can affect proper installation.
- Check wear before reuse. Inspect clamps for distortion, corrosion, missing fasteners and damage to the mounting rail. Compare the exact replacement listing before ordering.
