The Camco 40178 is a direct replacement vent lid for Ventline (pre-2008) and Elixir (post-1994) 14"×14" roof vents. A cracked, broken, or UV-damaged vent lid is one of the most common sources of RV roof leaks — replacing it promptly with a correct-fit lid restores the weatherproof seal and protects the roof from water intrusion.

Black polycarbonate resists cracking and impact better than original acrylic lids — a durable long-term replacement
Added center bar provides extra structural strength and stability — prevents flexing and cracking under load or wind
Arrives ready to install — all mounting hardware included, no additional parts needed
Standard sizing for the most common RV roof vent opening — compatible with Ventline pre-2008 and Elixir post-1994

Verify compatibility first: Confirm your vent is a Ventline (pre-2008) or Elixir (after 1994) before installing. Pre-assembled: The lid arrives fully assembled — no prep work needed before installation. Hardware included: All mounting screws and hardware are in the box — no need to source additional fasteners. Inspect the vent hinge and frame before installing the new lid. If the hinge or base frame is damaged, the lid may not seal correctly even with the correct replacement part.
