Identify RV Stove Hood Exhaust Vents: Ventline & Heng's Parts
If an RV stove-hood outside vent has a broken locking flap, cracked cover or missing damper, the replacement needs to match the original outlet. Ventline and Heng's both offer exterior range-hood vents, but the covers, collars and inner dampers are different components. This guide compares part numbers so you can identify what you have before ordering.
What part of the stove exhaust needs replacing?
Exterior cover or outletThe weather-facing exterior flange and cover sit on the outside wall. Compare its overall shape, latch position and MPN.
Wall collarThe duct collar passes through the wall toward the range hood. Its depth and shape matter when replacing the complete outlet.
Damper or flapThe hinged flap opens when the hood exhausts and closes when it stops. Some Heng's J116 configurations have separately available damper parts.

Ventline collar styles and Heng's damper differences
Ventline BV2111
The BV2111 options below are locking, non-louvered exterior outlets with different colour suffixes. Compare the body shape and wall opening rather than substituting another design by paint colour.
Ventline BV2250
BV2250-03R and BV2250-05R have a listed 9/16-inch collar projection, while BV2250-55R lists a 1 11/16-inch collar projection. Those different depths matter to the installation.
Heng's J116 outer covers
J116BK-CN is listed with an approximately 10.88 × 4-inch opening, while J116TBK-CN is listed with a 10⅝ × 3⅝-inch opening. Measure the actual wall opening and confirm the mounting pattern.
Heng's JRP-series dampers
JRP2120R (black) and JRP2121R (off white) are listed for the J116 hood. The separate JRP2126R is listed for the J116BK-C and J116TBK-C configurations.
Check before ordering: A ducted kitchen range hood must exhaust outside through an unobstructed, appropriately connected outlet. These parts are not general-purpose plumbing vents or replacement roof fan lids. A ductless recirculating hood does not use the same exterior exhaust arrangement.
Ventline and Heng's manufacturer part-number comparison
Use the MPN to distinguish closely related finishes and hardware arrangements. Not every part below has an independently documented wall cutout, so compare the existing part and manufacturer's instructions for the exact replacement.

Inspect exhaust covers, collars and dampers
These cards link to the exact catalog records. Use the product photograph to help identify the cover or damper, then confirm dimensions and the original mounting arrangement.
Ventline BV2111 exterior outlets
These are non-louvered locking Ventline exhaust outlets. The suffix identifies the colour: colonial, polar, Nu-Tru, frost white or black. Check the original exterior flange and locking-flap shape.
Ventline BV2250 exterior outlets
The BV2250-series covers include distinct collar configurations. Compare the old collar projection and mounting profile; do not substitute another BV2250 number just because the panel is black.
Heng's J116 exterior hood covers
These J116 exterior vent covers come in different opening styles and colours. J116BK-CN and J116TBK-CN are different MPNs with different listed openings.
Heng's replacement dampers
For a broken internal flap, first identify the installed Heng's hood assembly. JRP2120R and JRP2121R are listed for J116; JRP2126R is listed for J116BK-C and J116TBK-C.
Frequently asked questions
Can I replace a Ventline BV2250-03R with BV2250-55R?
Do not assume so. The listed collar projections differ, and the complete mounting geometry should be checked before selecting another BV2250 model.
Will a JRP2120R damper fit every Heng's J116 cover?
No universal interchangeability is established. JRP2120R is listed for the J116 hood, while JRP2126R is specifically listed for J116BK-C and J116TBK-C. Match the installed model number.
Can a ductless range hood use an exterior exhaust cover?
A ductless recirculating range hood does not normally have an exterior exhaust duct. Identify the actual hood configuration before buying an external cover.
Related RV ventilation and kitchen references
For complete range-hood replacements, see the Furrion range hood and grease-filter guide. For another exterior wall-exhaust design, compare the B&B Endura range vent collar guide. Roof-fan motor parts are covered separately in the Heng's roof-vent motor reference.
For installation and collar specifications, see Ventline's RV range-hood exterior exhaust information. Always follow the hood maker's ducting instructions and keep outside flaps free to open and close.
