Keep your Sunchaser awning secured and operating correctly with this genuine Dometic replacement arm lock. Designed as a direct OEM replacement for Sunchaser models 8271000, 8290000, and 8350000, this small but critical component holds the awning arm in the locked position during travel and storage -- preventing unwanted movement and potential damage to your awning fabric and hardware.
The arm lock is the mechanism that secures the awning's support arm in place when the awning is retracted. A worn, cracked, or missing arm lock can allow the arm to shift during highway driving, creating stress on the awning roller, fabric, and mounting hardware. Replacing it promptly with the correct Dometic part protects the rest of your awning system.
At just 0.05 lbs., this is a lightweight component, but its function is essential. Using the correct OEM part number -- 69-3131 -- ensures proper fit and engagement with the existing arm hardware on your Sunchaser awning without modification.
Part number 69-3131 is a factory Dometic replacement, engineered to the same tolerances as the original component on your Sunchaser awning.
Confirmed fit for Sunchaser awning models 8271000, 8290000, and 8350000. Check your awning model label before ordering.
Weighing just 0.05 lbs., this arm lock installs easily and adds negligible weight to your awning assembly.
