Great looking deck railing

Would Recommend

We really like this product line for deck railings. One important note for DIY installation: you need a rather large saw to cut this product. Do a couple test cuts first before cutting it to length. We found that our 12in miter saw did not have enough clearance to cut it and we have to be extraordinal careful to not mare the outer coating.

I wish when you order something and it is picked up that there was a pause on a response to give a person time to actually use the items.
