The CRIG-B directional interior air vent grill is a black decorative vent with a closeable face. It is intended for interior side-wall ventilation applications on trailers, campers, RVs, and enclosed trailers. The 4 inch grill face covers the opening, while the 2 inch tube is designed to fit into a 3 inch OD side-wall hole.
This is a measurement-driven part. The most important checks are the wall opening, the available depth behind the wall, and whether the grill face will cover the existing cutout cleanly.
Compatibility: Match this vent by measurement. It is listed for a 3 in. side-wall hole with a 4 in. diameter grill end.
Vehicle / System Fit: Commonly used for trailer, camper, RV, enclosed trailer, furnace cabinet, and motorcycle trailer ventilation applications.
Installation Notes: Confirm hole diameter and tube clearance before installation. Hardware, sealant, and exterior vent components are not listed as included.
Performance Insight: A closeable interior vent gives the installer a finished trim face while allowing the opening to be adjusted when airflow needs change.
Selling Brand: R&P Carriages / trailer camper RV vent component
Application Reference: Trailer, camper, RV, enclosed trailer, furnace cabinet, and motorcycle trailer references describe common use cases only.
What This Means: This listing is for one black directional interior air vent grill, not a guaranteed OEM-branded item unless specifically stated and verified.
Before Ordering: Verify hole size, wall depth, grill diameter, color, and whether your installation requires additional exterior vent pieces, hardware, or sealant.
This vent is a practical replacement when the original interior grill is missing, cracked, discolored, stuck open, or no longer matches the trailer interior. Fitment should be confirmed by measuring the existing opening instead of relying only on the trailer model.
The vent face can be closed when airflow is not needed and opened when ventilation is desired.
Provides a clean interior finish for trailer, camper, RV, and enclosed trailer side-wall vent openings.
The tube end fits into a 3 in. OD side-wall hole, making it useful for common trailer ventilation setups.
The black finish pairs well with darker interior trim, cabinet panels, and utility trailer hardware.
