I sell Azek as well as many other building materials, located in the Upper Peninsula of Michigan. The four holer shown above is for a 7.2 cu ft Magic Chef and used one piece of Azek 1x8x18' and a 4 oz. can of glue to construct.
1x6x12' 28.50, 1x6x18' 42.50, 1x8x12' 37.75, 1x8x18' 56.75, 4 oz adhesive 7.50
Azek has a website with a dealer locator

You would be looking for Azek trim not their decking product. Let me know if you have any other questions.
