Dometic Atwood Manual Lift Arm Kit K8011-05 – RV Roof Vent Replacement Arm, OEM Fit & Durable Hardware

The Dometic Atwood K8011-05 Manual Lift Arm Kit is a replacement lift-arm assembly designed to restore manual opening and closing of compatible RV roof vents quickly and reliably.

If an existing vent arm is corroded, bent, or no longer holds your roof vent open, this Atwood-manufactured Dometic kit provides the mechanical parts needed to get smooth, secure operation back. It’s a straightforward, budget-friendly repair part intended for owners who prefer to maintain original-style manual vents instead of replacing the entire dome or switching to powered units.

How will this kit improve my vent’s performance?

Replacing a worn lift arm removes binding and sag, so the vent dome opens evenly and stays positioned where you set it. The kit’s metal components are made to the original fit and function, restoring reliable manual control and preventing wind or vibration from forcing the vent closed.

• Restores smooth pivoting action and correct dome alignment
• Reduces rattles and vibration-related noise
• Re-establishes secure open positions to prevent draft issues

Is installation difficult for a DIYer?

Installation is designed to be simple and fast for someone with basic hand tools and a little experience working on RV interiors. The kit fits into the existing mounting points used by the original Atwood/Dometic lift arm so you generally won’t need to modify the vent or roof trim.

• Quick swap-out with common tools (screwdriver, wrench)
• Uses original mounting locations—no cutting or drilling required in most cases
• Clearances and hardware match factory specifications for straightforward alignment

What parts and materials are included and how durable are they?

The kit supplies the manual lift arm assembly and the hardware necessary to attach it to the vent mechanism. Components are built for typical RV conditions and will resist normal wear from repeated opening and closing, though long-term exposure to salt or extreme corrosion environments will still benefit from periodic inspection.

• Complete manual lift arm assembly compatible with Atwood/Dometic vents
• Matching mounting hardware for immediate replacement
• Manufactured to OEM-style tolerances for dependable fit and operation
