The pipe is 2" and the grab rail is 1 3/8", its 6'6" off the floor and the grab rail is 6'5" off. The base plat is 28" , the pipe is approx 24" cl at the bottom and 8.5" at the top. The Bimini is the same 1 3/8" pipe so it's real sturdy. The top side is 1 1/8" thick and it looks like they added another 1/4 or so under the arch area, Hope this helps

Thats great. I appreciate your time-

My 27 has a t-top versus the arch. I like the looks of the arch better, but the t-top was a little more functional from my standpoint - with the arch you can't have someone sitting on the gunwale adjacent to the console. Also, makes it easier if you are in the water next to the boat to toss stuff in or get stuff out. Either way, there are pluses and minuses. We are very happy with the t-top.
