B&B RV Slide-Out Rear Trim Covers: 94352, 94498, 94499 & 94500

Small rear trim covers finish the seam where RV slide-out extrusions meet near an outer corner. B&B Molders supplies several L-shaped transition profiles that look alike from a distance, but the width, length and left/right orientation vary. The complete outside dimensions and factory part number are more reliable than a general description such as “slide-out corner guard.”

What to check on the RV

The same finish does not mean the same size

94498 and 94500 are both polar white, but the factory lists different outside lengths. A 1½ × 2½-inch cap should not be substituted for the 1½ × 3³⁄₁₆-inch version without confirming the original extrusion profile and fastener points.

Left versus right

The manufacturer identifies 94351 as left-hand and 94352 as right-hand. If your original has an L-shaped directional lip, match the position and fastening orientation rather than simply turning a right-hand cover upside down.

Single-part replacements

These are individual trim-cover parts, not a complete slide-out corner assembly. Check the joint beneath the trim and any sealant or mounting screws before ordering. A cover may hide a seam, but it is not a substitute for repairing damaged slide-out structure or weather seals.

Before installing

1. Measure the original cover's entire outside shape, not just its 1½-inch side.
2. Compare hole locations, seam direction and any left/right designation.
3. Match the original OEM or aftermarket number if it is marked on the part.
4. Check clearance through the full slide-out travel and use the RV manufacturer's fastening and sealing method.
