Hello, I am looking for red oak square rails, probably 1 1/4 x36". My local big box stores do not have anything off the shelf (only outdoor fir) and I would prefer to see them or know that they are straight (I typically do not buy wood at the big box store). What is the best supplier for these simple long blocks/rails? I do not need dowels in it, I will screw top and bottom to top and bottom rail and one handrail on the top. Everything simple and easy. Thanks for your help
