The Vevor chimney cap is designed to protect outdoor masonry chimney flues from rain, snow, leaves, debris, birds, and small animals. Its 304 stainless steel construction offers durable all-weather performance with resistance to heat and water. The adjustable bottom design helps fit a range of clay flue tile sizes for flexible installation. Uniform mesh sides promote ventilation while adding spark arrestor protection. Pre-drilled holes and included hardware make installation easier for one person.
