PPG 5/4 in. x 7-1/4 in. x 9-1/4 in White Smooth Artic R and R 4 in. Vent Block 4-1/4 in. Hole

It only makes sense to have Portland Products Group produce the quality custom blocks you require to save time, money and labor. From large multi-family jobs to single residential builds, we've got you covered. PPG is very proud to have been given the right to use the Recommended by James Hardie logo since all of our blocks are made from the James Hardie Fiber Cement Trim Products. These PPG Fiber Cement Vent Blocks were created to be used with most 4 in. vent pipes with hood. Great for new construction, multi-family builds and residential remodeling.
