This rail-mount rod holder fits 7/8"-1" rails. It easily adjusts to any angle up and down, side to side. All parts are constructed of marine-grade stainless steel to prevent rust and corrosion. The mounting hardware is included. The inside of rod holder is coated with a special no-scratch lining to protect your rod and reel. No other parts needed. Per each.
I have used several rail mount rod holders and these are the best. They mount solid without slipping around and are adjustable to get the angle you need. Also a very good price!
