If your RV's large electrical cable hatch is cracked or no longer closes properly, first identify whether the door or the entire open-back housing needs replacement. B&B Molders' 94337, 94338 and 94339 all use the same large wall opening, but have different door finishes and lock styles.

Compare the three large hatch assemblies

Complete hatch Finish Door lock Cutout and face
94337 Polar white Keyed Cutout 6 7/8 × 6 3/8 in; face 8 1/2 × 8 in
94338 Black Keyed Cutout 6 7/8 × 6 3/8 in; face 8 1/2 × 8 in
94339 Polar white Thumb latch Cutout 6 7/8 × 6 3/8 in; face 8 1/2 × 8 in

For this large family, the manufacturer specifies a 1 1/8-inch collar depth. These hatches allow a compatible 30- or 50-amp RV power cable to pass through the smaller cord-access opening when the door is shut. The cable hatch itself is not a power connector.

Factory-matched door replacement numbers

The manufacturer lists 94186 as the polar-white door replacement and 94187 as the black door replacement. Match the original hinge and the door's lock arrangement; a separate replacement door is not a complete wall hatch and should not be treated as a complete lock set.

Measure before ordering

  1. Measure the wall opening: the large family requires approximately 6 7/8 × 6 3/8 inches.
  2. Confirm the outside face covers the opening and previous fastener locations; the specified face is 8 1/2 × 8 inches.
  3. Match the original door colour and whether it uses a key or thumb latch.
  4. Compare the collar clearance inside the wall and follow the RV manufacturer's sealing instructions.
