Ready to replace a worn port or add a clean pass-through on your rig? Round RV access doors in a multi-purpose hatch style handle sewer hose ports, shore power cords, generator or A/C pass-throughs, and simple tank access with a sealing cap. Match your cutout and hole size—options include 6-3/4" diameter doors with a 5" opening or installs that use a 4 inch hole saw—and pick black or white to blend in.
Yes, black and white options are available. Pick the color that blends with your trailer or compartment; some users match an existing port for symmetry. If you're covering a generator encasement or fuel area, choose the color that best hides marks and fits the look you want.
Direct replacement caps aren't always available, so plan to replace the entire hatch if a cap can't be sourced. Check your required opening; a 5" hole opening with a 5-1/2" diameter x 3/8" deep cutout is common on some units. After install, screw the cap on carefully and fully to help keep it from backing off.
Match the cutout and opening to your application. Common specs include a 5-1/2" diameter x 3/8" deep cutout with a 5" hole opening, and an overall diameter around 6-3/4". Measure the existing hole and the item passing through; sewer hose knuckles may need a larger opening. If replacing, compare to the old part so the fit and operation stay the same.
Confirm the cutout size and depth; some call for a 5-1/2" diameter x 3/8" deep cutout, while others use a 4" hole saw. Clean off old caulk before mounting to help sealing. Some units include a waterproof seal to prevent leakage—verify in the specs. If reusing holes, compare the hole pattern to your OEM part first.
Yes, these are commonly used for sewer hose pass-throughs and shore power cord access. Make sure the opening is large enough for hose fittings to pass without removing connectors. For cord hatches, a screw-in cap design can be secure and simple to use. When closed, verify the seal seats well to reduce drafts and moisture.
