RV Mushroom Vent Cap

Key Features

• Detachable Dome Design – Snap-on/off cap separates from the base in seconds; clean or inspect the vent without tools
• Rain & Bug Proof – Mushroom dome shape deflects rain and blocks insects from entering the vent pipe
• Durable PP Material – UV-resistant polypropylene; won’t crack, yellow, or warp under sun and weather exposure
• Wide Flange Base – 5.28" (13.4cm) flange with multiple screw holes for a secure, flush mount on any flat roof surface
• Wide Application – Fits RV rooftop vents, boat cabin vents, and residential roof vent pipes

Problems Solved

• Stops rainwater from entering vent pipes and causing interior water damage
• Blocks insects and debris from nesting inside ventilation ducts
• Replaces cracked or yellowed vent caps that no longer seal properly
• Eliminates difficult cleaning — dome lifts off for direct access to the vent opening
