Review on 🔲 Heng's 90112-C1 Universal Vent Lid - 14 x 14 Inches, Smoke by Jacob Sriubas

It's thinner than the dome it replaced. However, the arched one left room for a fan motor. Having never used a fan I just took it off and it fit perfectly. I was a little concerned that this replacement metal cap would be noisy when it rained. I was surprised that a styrofoam sheet was taped to the underside of the lid to muffle the sound of the rain and maybe add some insulation. It was more than stated in the description. I measured it at 15 x 15.25 inches outside and outside - it fit perfectly. I am very satisfied as it never needs to be replaced compared to the plastics I had to replace twice.
