Lonsda Left RV Awning Head Cover End Cap for Solera/Lippert 643923 — ABS, Includes Screws

This Lonsda 643923 left awning head cover end cap replaces the left-side Solera/Lippert awning motor cover to protect components from water, dust, and debris.

If your RV awning isn’t retracting smoothly or the plastic end cap is cracked or missing, swapping in a quality replacement end cap restores protection to the awning idler head. The Lonsda 643923 is molded from durable ABS plastic and designed to match Solera/Lippert geometry so it fits in place of the factory left-side cover without modification. It includes two replacement screws so you can finish the swap quickly and get your awning back to reliable operation.

How do I know this end cap fits my awning?

Confirm fit by matching the part number and side orientation: this piece is explicitly for Solera part number 643923 and installs on the left side of the awning motor assembly. It is not a universal cap and will not fit the right-side position.

• Direct replacement for Solera/Lippert part number 643923
• Left-side orientation only — verify which side is needed
• Shape and mounting points match factory geometry for easy swap

What does the Lonsda end cap protect against?

The cap shields the awning idler head and motor area from environmental exposure so internal parts remain cleaner and wear less quickly. Keeping moisture and grit out helps the awning extend and retract reliably and reduces the chance of corrosion or mechanical binding.

• Water-resistant ABS blocks rain and splashes
• Seals out dust and road debris that cause abrasion
• Prevents direct impact damage to the motor head during travel

Is installation difficult and what’s included?

Installation is straightforward: remove the old left-side cover, align the new Lonsda cap with the factory mounting points, and secure with screws. Lonsda supplies two replacement screws in case the originals are missing, so most replacements take only a few minutes and basic tools.

• No special tools or cutting required
• Includes two replacement screws for immediate installation
• Pre-drilled mounting points align with Solera/Lippert hardware

What material is it made from and how does that hold up?

This left-side head cover is fabricated from high-grade ABS plastic chosen for impact resistance, UV durability, and heat tolerance. The combination of stiffness and weather resistance means the cap resists warping, cracking, and discoloration under normal camping and travel conditions.

• ABS construction resists sun, rain, and temperature swings
• Maintains shape under repeated awning use
• Easy to clean and less likely to chip than brittle plastics

Who this is for: RV owners or repair shops replacing a damaged or missing left-side awning head cover on Solera or Lippert-equipped trailers and motorhomes. Choose this Lonsda 643923 end cap if you need a precise left-side replacement that restores component protection and installs with minimal effort. If you require a right-side cap, confirm the correct part number before ordering.
