Sea-Dog 201070-1
Small rectangular leaves for flush door or cabinet-edge mounting.
Sea-Dog Marine Door Hinges: Butt, Short-Side & Concealed
Replacing a boat cabinet or hatch-door hinge is easier when you compare the entire hinge, not only its outside dimensions. Sea-Dog makes flush-mortised butt hinges, unequal-leaf hinges for restricted mounting space, and a concealed design for doors where visible hardware is undesirable. The six models below are separate parts with different leaf layouts and screw requirements.
Compare Sea-Dog hinge part numbers
Dimensions are in inches and follow Sea-Dog's A × D drawing references unless otherwise noted. These figures are not a substitute for checking hole positions and door clearance.
| Manufacturer part no. | Hinge style | Drawing dimensions | Installation screws |
|---|---|---|---|
| 201070-1 | Compact mortised butt hinge | 1-1/4 × 1-1/2 in | 4 × #8 flat-head |
| 201080-1 | Rectangular butt hinge | 2 × 3 in | 6 × #8 flat-head |
| 201081-1 | Square butt hinge | 3 × 3 in | 6 × #8 flat-head |
| 201510-1 | Short-side door hinge | 2-1/8 × 1-1/2 in | 5 × #8 flat-head |
| 201530-1 | Door hinge | 2-7/8 × 1-1/2 in | 6 × #8 flat-head |
| 201954-1 | Flush concealed hinge | A 1-7/8; D 1-1/2 in | 5 × #6 flat-head |
Fasteners are separate. The screw counts and sizes above are Sea-Dog's specified installation requirements; flat-head screws are not supplied. Confirm the mounting substrate before selecting screws.
What to check before choosing a replacement
- Door and frame faces: identify whether the original hinge uses equal leaves, an unusually narrow leaf, or a concealed offset.
- Mortise and movement: note whether the leaves sit in recesses and whether the door swings clear of adjacent trim.
- Hole pattern: measure all existing screw centres; matching outer size alone does not establish a drop-in fit.
- Concealed hinge geometry: the 201954-1 has a separate B dimension of 2-3/4 inches. Compare its full shape rather than treating it as a standard rectangular butt hinge.
- Material: these six models use stamped 304 stainless steel. For hatch hinges with removable pins or different mounting geometry, see the separate hatch-hinge guide when available.
