Heng's Range Vent Exhaust Cover – Black
Save time and money! Heng's Black RV Range Exhaust Cover prevents the need to replace the entire vent. In some instances, a simple damper replacement will fix the RV range hood ventilation. The vent damper consists of an attractive exterior vent cover designed to keep rain and dust out of your camper with an outside manual release tab. Once the outside manual release damper is unsecured, the damper automatically opens when the range hood fan is activated to allow cooking odors and smoke to be exhausted. Damper automatically closes to prohibit insects and dust from entering when the range hood is not in operation. Manual release damper must be secured before traveling. Dimension Installed 13 L x 6 W x 2 D Cut Out 10-1
