The back flange 1 1/2" will accommodate a male 4” SDR35, Triple Wall, or a S&D, it is constructed of 16 gauge aluminum. This can be installed loose or glued in.
This has the best fit and finish by far for retaining wall drain discharge. All the others out there are plastic and cheap looking. I did also did not go with the others because they do not direct water away from the wall foundation like this does. This is quality stainless steel and is worth every penny. The fit is perfect and looks awesome
This unit looks great, and made of high quality product. I would definitely use this product again.
Great - simple, clean. We used it only Pisa2, and it worked perfectly. Even had other landscapers asking about where we found it. Stands above ****** alternatives from Home Depot or wherever else people dig their drains up.
Great piece , fits pipes perfectly would use again.
