The CAMCO MFG 40310 is a bumper cap set designed to seal and protect vent terminations on RV or mobile unit exhaust openings. The set includes one magnetic cap with lugs and one insect screen, working together to block insects and debris from entering the vent while allowing proper airflow when the system is in operation. The magnetic attachment method allows for fast removal and reinstallation without tools. This hardware is typically handled by service technicians working on RV systems, mobile HVAC units, or similar vented appliances requiring weatherproof termination covers.
The 40310 is suited for use on vent terminations where a secure, removable cap is needed to prevent pest intrusion and environmental contamination. The included insect screen adds a secondary barrier against insects entering the vent opening. The magnetic cap with lugs provides a positive retention method that stays in place during travel or operation while remaining easy to remove for service access. This set is sold as a package of 3 units, making it practical for fleet service or multi-unit maintenance work.
Designed as an OEM-style replacement bumper cap set for RV and mobile unit vent terminations requiring magnetic cap coverage with integrated insect screening.
Installation is performed by RV service technicians or qualified HVAC service personnel. Before installing or removing the cap set, ensure the associated appliance or vented system is powered down and cooled to a safe handling temperature. Align the magnetic cap with lugs over the vent termination opening and confirm the insect screen is seated securely before returning the unit to service. Do not obstruct the vent opening in any way that restricts required exhaust airflow.
