Heng's 14 x 14 Radius Roof Vent | Colonial White Metal Base, Non-Powered

This Heng's roof vent is a standard replacement for a 14" x 14" opening — a self-centering metal base drops into place without the usual alignment headache, and the radius corners match most factory openings.

• Self-centering metal base for a straightforward install in a 14" x 14" opening
• Radius (rounded) corners standard on this base
• Bug screen lets air circulate while keeping insects out
• Hand-crank lid opens and closes securely
• Colonial White metal base with a white acrylic lid and screen frame
• Non-powered — manual vent, no electric fan

It's a manual, non-powered vent: crank the acrylic lid open for airflow, and the built-in screen keeps bugs out while you do it.
