A replacement RV shore-power cord hatch needs to match the opening through the RV wall, not simply the approximate width written on a product label. B&B Molders makes small and medium 30/50-amp cord-access hatches with different wall cutouts, outside faces and replacement door numbers.

Small versus medium cable hatch dimensions

Hatch family Complete hatches Wall cutout Outside face Door only
Small 94333 white/thumb; 94334 white/key 4 3/4 × 4 1/4 in 6 1/2 × 6 in 94178
Medium 94335 white/thumb; 94336 black/key 4 3/4 × 5 7/8 in 6 1/2 × 7 5/8 in 94182 white; 94183 black

How the two hatch sizes differ

Small hatch: 94333 and 94334

The small family uses a 4 3/4 × 4 1/4-inch wall cutout, a 6 1/2 × 6-inch outside face and a shallow 3/8-inch collar. Both are polar white; choose 94333 for a thumb-latched door or 94334 for a keyed door. For a damaged matching door, the manufacturer's replacement number is 94178.

Medium hatch: 94335 and 94336

Medium hatches use a different 4 3/4 × 5 7/8-inch cutout and a 6 1/2 × 7 5/8-inch outside face. The collar is 1 1/8 inches deep. 94335 is the white thumb-latch assembly and 94336 is the black keyed version; their door-only replacements are 94182 (white) and 94183 (black).

These are open-back cable-access hatches with a small pass-through door intended for a compatible 30- or 50-amp RV power cord. They are not electrical outlets or adapters and do not change the circuit's rating.

Choosing a complete hatch or a door

If only the door is cracked, compare the hinge, edge profile, colour and original hatch size to a door-only number. If the wall flange or housing is damaged, choose by the manufacturer's full cutout, outside dimensions and collar clearance. The complete hatches and loose doors are different products.

Need a larger opening? See the large 94337–94339 cable-hatch guide; those larger doors do not use the small/medium replacement numbers.
