Lippert 643921 Solera Regal Awning Head Assembly Back Cover -- Black
A direct-fit OEM-style replacement back cover that closes out the rear of your Solera Regal awning head assembly, keeping road grime, debris, and moisture away from the internal drive and idler hardware. If your original cover is cracked, missing, or discolored, this is the part that puts it right.
The back cover of your Solera Regal head assembly does a quiet but important job -- it keeps the internal gear drive, motor housing, and idler arm pivot points shielded from the elements every time your awning extends and retracts. A cracked or missing cover lets road spray, insects, and UV-degraded debris work their way into precision components that are far more expensive to replace than the cover itself.
Lippert part number 643921 (vendor reference 72-3825) is the correct replacement back cover for the Solera Regal head assembly. It is molded in black to match the standard Regal head housing finish and is designed to snap or fasten back into place using your existing hardware.
Engineered specifically for the Solera Regal head assembly -- not a universal patch. Replaces the factory cover directly.
Compatible with both power-operated and manual Solera Regal awning configurations sharing the same head assembly housing.
Matches the standard Regal head assembly color. No painting or finishing required for a clean, factory appearance.
Shields internal drive gears, motor hardware, and idler pivot components from dirt, moisture, and UV exposure.
The Solera Regal head assembly houses the entire operating mechanism of your awning -- the drive motor (on power models), the idler arm tension spring, and the gear interface that translates motor torque or hand-crank input into fabric deployment. The back cover closes the rear face of this assembly, sealing off those internals from the rear-facing direction -- where road debris, rain runoff from the roof edge, and dust accumulate during travel.
Without an intact back cover, grit can migrate into grease-packed surfaces and accelerate wear. On power models, moisture intrusion near the motor housing can lead to corrosion of electrical contacts. Replacing a damaged cover promptly is one of the lowest-cost preventive maintenance steps available for a Solera Regal awning.
This cover is designed to reuse your existing mounting fasteners or retention clips from the original cover. Before ordering, confirm the head assembly on your awning carries the Solera Regal designation -- the head housing style differs from the Solera Flat and Solera Plus product lines, and covers are not interchangeable between lines.
The Solera Regal awning is identified by its tapered head assembly profile and the Regal label on the housing end cap. If you are uncertain whether your awning is the Regal variant, check the awning label on the head assembly endcap or cross-reference your RV's build sheet against the awning model callout. Lippert's Solera lineup includes several distinct head assembly shapes -- ordering by part number 643921 ensures you receive the cover designed for the Regal housing geometry.
This part is also referenced under vendor part number 72-3825. Both numbers identify the same component. Use either number when searching supplier catalogs or requesting dealer assistance.
When reinstalling the back cover, inspect the internal drive and idler components for debris accumulation before closing the assembly. A quick wipe-down and inspection of grease points at the same time the cover is replaced can extend awning service life significantly. Do not use petroleum-based solvents on plastic housing components -- mild soap and water is sufficient for cleaning.
