Broken, cracked, or missing the door on your Lippert slide-out switch hatch box? This OEM-style replacement door snaps the repair together fast. The Lippert 258403 is the black plastic hatch door with a pre-drilled hole sized for the slide-out switch or wiring pass-through, designed to fit directly onto Lippert slide-out control hatch boxes found on a wide range of travel trailers, fifth wheels, and motorhomes.
A damaged or missing hatch box door exposes the slide-out control switch and wiring to road debris, moisture, and UV degradation. Replacing the door quickly protects the switch mechanism and keeps the slide-out operating reliably. This Lippert 258403 door is built to OEM specification, so fitment is straightforward -- no drilling, trimming, or modification needed in most applications.
Lippert slide-out hatch boxes are standard equipment on a large percentage of towable and motorized RVs built over the past two decades. If your rig uses a Lippert slide-out room extension system, this door is the correct replacement part for the exterior or compartment-mounted hatch that houses the rocker switch or control interface.
Designed to match the original Lippert hatch box housing dimensions for a direct, no-modification replacement.
Hole is factory-punched to accept the slide-out control switch, saving time and preventing fitment errors.
Black plastic construction resists fading and cracking from sun exposure common in outdoor RV applications.
Keeps moisture and road grime away from the slide-out switch and associated wiring for longer system life.
This door is a Lippert-branded OEM part, not an aftermarket approximation. Using the correct part number (258403) ensures the door secures properly to the existing hatch box frame without gaps or fit issues.
Lippert slide-out switch hatch boxes are small enclosures mounted on the exterior or interior sidewall of the RV, housing the rocker switch used to extend and retract the slide-out room. Over time the door on these boxes can crack from thermal cycling, get broken during transport, or simply go missing. This part replaces only the door panel -- the hatch box body and switch are separate components.
This listing covers the replacement door panel (Lippert 258403) only. The hatch box housing, rocker switch, wiring harness, and any fasteners are sold separately. Verify your existing hatch box body is undamaged before ordering only the door.
