The Camco 40177 is a direct replacement vent lid for Ventline (pre-2008) and Elixir (post-1994) 14"×14" roof vents, constructed from black polypropylene. Like its polycarbonate counterpart (40178), this lid arrives pre-assembled with all mounting hardware included for a quick, straightforward installation. The reinforced center bar adds structural rigidity to resist flexing and cracking under wind load.
A cracked or broken 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 and interior from water damage.

• (1) Camco 40177 Black Replacement Vent Lid (pre-assembled) • Mounting hardware
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. 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.
Both lids fit the same Ventline/Elixir vents and share the same dimensions, hardware, and reinforced center bar design. The only difference is material: 40177 (this product): Black polypropylene 40178: Black polycarbonate Polycarbonate generally offers higher impact resistance and better UV stability for long-term rooftop use. Polypropylene is a durable and cost-effective alternative. Either is a suitable replacement for a standard Ventline or Elixir vent lid.
