B&B RV Sewer-Hose Storage Hatches 94302/94303: Doors & Parts

An RV sewer-hose storage hatch covers the end of a hose-storage compartment built from a suitable rigid or flexible tube. B&B Molders offers matching 94302 white and 94303 black hatch assemblies, plus separately identified door replacements. These hatches are storage access points, not wastewater outlet valves.

Match the mounting opening

For both complete hatches, the manufacturer specifies a 4 3/4 × 5 7/8-inch wall cutout and 6 1/2 × 7 5/8-inch outer frame. The collar is 2 1/2 inches deep. Compare all three measurements with the existing RV wall and any storage tube behind it.

How the sewer-hose compartment fits together

The hatch provides the exterior access door and mounting assembly. Its backplate is designed to accept a suitable 4-inch rigid PVC pipe or flexible hose as the storage compartment. That tube is not included with the hatch. It must be mounted and supported appropriately in the RV's available space.

Replacing a door instead of the whole hatch

When the frame is sound but the access door is damaged, the factory parts list identifies 94184 as the polar-white door and 94185 as the black door. Check your original hinge and latch geometry before selecting a door-only replacement.

Before ordering

1. Measure the wall cutout and outside frame dimensions, not the sewer hose diameter alone.
2. Check the wall clearance behind the hatch for its 2 1/2-inch collar.
3. Confirm the hose-storage tube will accept the hose and fittings you actually own.
4. Compare the original door and latch style before buying only a door.
