We bought these years ago when we had a 30' Sportcraft and never got around to putting them on the boat. I'm wondering what would be a fair asking price for these. I have 3 straights and 2 corners. They measure 14 1/4" high. The top and bottom of the straights and the bottoms of the corners are 4" X 4". The top of the corners are 8" X 8" with a 4" X 4" cutout. they are adjustable and have two set screws from the bottom to lock them in place.
