Identify Sea-Dog Marine Door Hinges by Part Number
When identifying a removed boat-door hinge, start with the stamped part number if it is still legible. Where there is no number, compare the hinge leaves, overall dimensions and screw pattern. These Sea-Dog 201-series parts include conventional butt hinges, a short-side design and a concealed model; they are not interchangeable simply because they are stainless.
Identify the original hinge
Dimensions are in inches, using Sea-Dog's drawing-letter references where specified. Match the manufacturer's full part number rather than relying on appearance alone.
| Sea-Dog part number | Hinge type | Manufacturer dimensions | Installation fasteners |
|---|---|---|---|
| 201070-1 | Small mortised butt | 1-1/4 × 1-1/2 in | Four #8 flat-head |
| 201080-1 | Butt hinge | 2 × 3 in | Six #8 flat-head |
| 201081-1 | Square butt | 3 × 3 in | Six #8 flat-head |
| 201510-1 | Short-side door | 2-1/8 × 1-1/2 in | Five #8 flat-head |
| 201530-1 | Door hinge | 2-7/8 × 1-1/2 in | Six #8 flat-head |
| 201954-1 | Flush concealed | A 1-7/8; B 2-3/4; D 1-1/2 in | Five #6 flat-head |
Installation note: fastening screws are not included. Dimension letters refer to the manufacturer drawing; verify hole centres and mounting surfaces separately.
How to recognize the correct version
- Overall dimensions: measure the full leaf span and knuckle height as shown in the table.
- Leaf shape: note equal leaves, a short side or concealed mounting.
- Mounting: check whether the original hinge was mortised into the frame or fastened behind the door.
- Holes and clearance: measure the existing screw centres and door swing. The same overall size does not guarantee fit.
