Overview
The CRIG-B directional interior air vent grill is a black decorative vent with a closeable face.

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.
R&P Service Insight
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.
- Hole Check: Match to a 3 in. OD side-wall opening.
- Depth Check: Tube depth is 2 in.; verify clearance inside the wall or cabinet cavity.
- Finish Check: Black finish is best for matching black trim, black cabinet hardware, or darker trailer interiors.

R&P Repair Insight
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.
- Measure First: Confirm the existing side-wall hole is 3 in. before ordering.
- Check Coverage: The 4 in. grill face should cover the visible opening cleanly.
- Confirm Vent Pairing: If using with an exterior vent, verify that the outside vent and inside grill are compatible by measurement.
