Cracked, faded, yellowed, or missing awning end cap? Lippert part 643920 is the factory replacement front cover for the idler head on Solera Regal roller awnings. It snaps into place to protect the internal idler mechanism from road debris and moisture, and restores a clean finished look to the non-drive end of your awning. An inexpensive, direct-fit repair that keeps your Solera Regal looking and working like new.
The Solera Regal is Lippert's mid-range roller awning line, found on a wide range of travel trailers, fifth wheels, and Class A and Class C motorhomes. The awning roller assembly has two end heads -- the drive head (motor or hand-crank arm side) and the idler head (the passive, non-drive end). This part is the front cover for the idler head, meaning it caps the outward-facing side of the idler housing at the non-drive end of the roller tube.
UV exposure, wind stress, and road vibration can crack or dislodge this cover over time. Once it is missing or broken, the internal idler bushing and spring components are exposed to water intrusion and debris -- which accelerates wear and can lead to a noisy or uneven awning roll. Replacing this cover is a simple snap-on repair that takes minutes and costs far less than ignoring the damage.
Designed by Lippert for exact fitment on Solera Regal idler head assemblies -- no trimming or modification needed.
Matches the standard white color of Solera Regal end hardware for a clean, factory-matched appearance.
Clips onto the idler head housing without tools. No drilling, no fasteners required for most applications.
Keeps moisture, road grime, and insects out of the idler housing to extend the life of internal roller components.
The idler head front cover is a cosmetic and protective cap -- it does not carry structural load or tension. Its job is to seal the outward face of the idler head housing. If your awning rolls unevenly or is noisy, inspect the idler bushing and spring inside the housing as well; this cover alone will not correct mechanical issues inside the roller.
Lippert produces several Solera awning lines -- including the Solera V, Solera Flat, and Solera Regal. End caps and head covers are not interchangeable across these lines. Confirm your awning is specifically the Solera Regal series before ordering. The model name is typically printed on the awning fabric valance or on the drive head housing label. Lippert part 643920 (vendor part 72-4486) is specific to the Regal idler head.
The Solera Regal roller has two distinct end covers. This part -- 643920 -- is the idler head front cover, which is the non-drive, non-motor end. If your damaged cover is on the end with the motor, hand-crank arm, or tension adjuster, you need the drive head cover instead. Check both ends before ordering to make sure you are replacing the correct side.
When reinstalling or replacing this cover, inspect the idler head housing for cracks or worn bushings. Apply a small amount of dielectric grease to the idler bushing contact points to reduce wear and prevent corrosion before snapping the new cover into place. Recheck the cover seating after the first few awning cycles to confirm it has not loosened.
If you are servicing your Solera Regal awning, consider also checking the drive head cover, awning fabric, roller tube end caps, and awning arm hardware. Lippert offers a full range of Solera Regal replacement components through authorized dealers and RV parts retailers.
