Dundas Jafine 4-Inch Roof Vent Cover - RL4P

Dundas Jafine 4-Inch Roof Vent Cover - RL4P

Restore protected rooftop exhaust termination with this Dundas Jafine 4-inch roof vent cover. The cap helps route exhaust air outdoors through the roof while protecting the duct opening from rain, snow, and backdraft.

RL4P is a universal/spec-match 4-inch roof exhaust cap for venting applications, not a model-specific appliance part. It provides an exterior roof termination for compatible bathroom, kitchen, laundry, or exhaust duct runs and helps reduce backdraft and weather entry when installed correctly.

Compatibility: For compatible 4-inch duct roof exhaust applications. Dundas Jafine lists RL4P as a black 4-inch roof exhaust cap for kitchen or bathroom fan roof venting.

Fitment / What To Verify: Verify 4-inch duct size, roof application, roof pitch/installation method, local code, exterior clearance, and whether the application is dryer, bath fan, or kitchen exhaust. Dryer venting must remain serviceable and free of lint-trapping restrictions.

Please confirm fitment with your appliance model number before ordering.

Is it time to replace?

• Common Symptoms: Broken exterior cap, missing damper, roof exhaust opening exposed to weather, backdraft, or pest entry around the vent termination.
• Visible/Sensory Cues: Cracked cap body, stuck damper, missing collar, loose flashing area, or an exterior exhaust termination that no longer seals correctly.

Pro Tip: Keep exterior exhaust caps accessible for cleaning. Screens and dampers can collect lint or debris and should be inspected regularly in dryer applications.
