Cracked, faded, or missing awning end cap? This is the factory replacement front cover for the idler head on Lippert Solera Regal roller awnings. It snaps into place to protect the internal idler mechanism, restore a finished appearance to the non-drive end of your awning, and keep road debris and moisture out of the roller housing. An inexpensive fix that keeps your Solera Regal awning looking and working like new.
The Solera Regal is Lippert's mid-range manual and automatic 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 manual 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 end of the roller tube.
Over time these plastic covers crack from UV exposure, get knocked loose in transit, or break during awning removal. Because the idler head houses the spring tension mechanism and the end of the roller tube, leaving it uncovered exposes those components to rain, dirt, and corrosion. Replacing this cover is a simple repair that takes minutes and requires no special tools.
Factory Lippert part number 643920, designed specifically for the Solera Regal idler head. No modification or adapter needed.
Matches the standard white housing color used on Solera Regal awning assemblies, keeping the end of your awning looking clean and complete.
Seals the non-drive end of the roller against moisture, insects, and road grime that can degrade the spring tension and roller bearings over time.
Weighs only 0.34 lbs and measures approximately 9.16" x 4.61" x 3.49" -- easy to store as a spare and quick to swap in the field.
Lippert's Solera awning family covers several product tiers -- Solera Standard, Solera Regal, and Solera Power. The Regal variant is distinguished by its enhanced end cap styling and is commonly paired with both manual pull-strap operation and the Solera Power automatic motor system. The Regal roller assembly is identifiable by its rounded, contoured end head housings rather than the flat-profile caps used on base Solera models.
The idler head is the passive end -- it holds the opposite end of the awning roller tube from the drive mechanism, allowing the tube to spin freely as the fabric extends and retracts. The front cover is the outward-facing decorative and protective cap on that head.
Lippert supplies awning components under the Solera brand to many OEM RV manufacturers including Forest River, Coachmen, Keystone, Heartland, and others. If your awning end cap or roller head housing has "Solera" or "Lippert" molded into it and it matches the Regal style profile, part 643920 is the correct OEM front cover for the idler end.
