Heng's 31121-C2
Compact white manual escape hatch with screen and interior garnish. Match the original roof opening and flange before ordering.
Heng's RV Escape Hatch Sizes, Complete Units & Lid Part Numbers
Heng's manual RV escape hatches combine a large screened opening with an opaque white lid and an interior garnish. They are not ordinary 14-inch roof vents. Compare the five complete assemblies by their exact manufacturer numbers, and use the lid cross-reference to find a replacement when the original frame remains serviceable.
Complete escape hatch part numbers
The figures below are nominal model designations, not roof cutout dimensions. Lid references are shown to help identify an existing hatch; a complete assembly includes more than the lid.
| Complete hatch MPN | Nominal hatch size | Opening shape | Replacement lid reference |
|---|---|---|---|
| 31121-C2 | 13 × 20 in | Rectangular | 90007-C1 (lid reference) |
| 58621-C2 | 15 × 22 in | Rectangular | 90008-C1 |
| 48621-C2 | 17 × 24 in | Rectangular | 90088-C1 |
| 66621-C2 | 22 × 22 in | Square | 90129-C1 (lid reference) |
| 68631-C2 | 26 × 26 in | Square | 90014-C1 |
Size labels are not roof-cutting dimensions. The nominal 13 × 20, 15 × 22, 17 × 24, 22 × 22 and 26 × 26-inch designations do not equal the outside mounting-flange size or necessarily the required roof rough opening. Measure the installed frame and use the installation drawing for the exact hatch before cutting or replacing roof material.
Checks before selecting a replacement
- Identify your complete assembly: match nominal size and MPN before ordering a new frame.
- Confirm the actual roof cutout: a hatch's stated 15 × 22-inch size is not the cutting template. Verify the exact frame and flange.
- Check the supplied pieces: these complete manual hatches include a screen, opaque white lid and interior garnish.
- Test egress: the lid, screen and emergency release must operate freely after installation.
- Use the correct service lid: the 13 × 20 hatch is associated with 90007-C1, while the 26 × 26 current style uses 90014-C1; other sizes have different numbers.
