Expert Verdict — Reviewed by the SuperArbor Pro Desk

Keep a spare top on hand for quick replacement after storm damage or on maintenance visits. Match the cap to the base size and profile for a proper seat. The 10 inch cap serves larger exhaust applications where 4 to 8 inch caps are undersized.

Secure the cap firmly to the base so it cannot dislodge in high winds or become a rooftop hazard.

Order the ACM Aluminum Code Cap Top to cap your roof exhaust vent in the size you need.
