94305 — Polar-white flush-mount access hatch
Open-back, flush-mount access hatch with a keyed door and no collar.
View 94305 productB&B 94305 & 94308 RV Flush-Mount Hatches: Doors and Cutouts
Two access hatches can look identical from the outside yet differ at the cutout, collar or locking arrangement. B&B Molders 94305 and 94308 are a matching pair of flush-mounted, open-back RV multi-purpose hatches. Both use the same opening and outer trim, with a choice of white or black.
Compare the two flush-mount hatches
| Part | Colour | Wall opening | Outside face | Mounting style |
|---|---|---|---|---|
| 94305 | Polar white | 6⅞ × 6⅜ in | 8½ × 8 in | Keyed; no collar |
| 94308 | Black | 6⅞ × 6⅜ in | 8½ × 8 in | Keyed; no collar |
Outside trim: 8½ × 8 inches
Wall cutout: 6⅞ × 6⅜ inches
Simplified size reference, not to scale. Check rear collar clearance: No collar.
What the original parts are
The outer door closes over the opening, while the mounting frame covers the wall cutout. An open-back, flush-mount design allows access through the wall without a deep enclosed box. Confirm there is safe clearance behind the panel for any equipment or plumbing the compartment contains.
B&B lists 94340 as the polar-white replacement door and 94341 as the black replacement door for these flush-mount versions. A door number is not a complete hatch assembly. Verify the original hinge and lock geometry before ordering a door separately.

View 94308 productKeyed lock details
The factory catalog identifies separate OEM key configurations, including a 391-key version and a 751-key version. These describe lock-cylinder arrangements, not a guarantee of which key is supplied with an individual retail package. If a shared key is important, compare the actual lock code.
Before replacing a hatch
- Measure the actual opening through the RV wall. Do not use only the exposed face dimensions.
- Check for a flush mounting arrangement without an inward collar.
- Match the original door colour, hinge location and key configuration.
- Confirm the wall has suitable support for fastening and apply the RV manufacturer's exterior sealing instructions.
