I purchased this past Xmas at a kayak retailer on the gulf coastline and have not made use of it. It is aluminum and is adjustable from about 14”-30” about. Quite properly made. Slides into rod holders to continue to keep it secured. In the New Smyrna/Daytona location and I’d like to do pick up only. Inquiring maybe $40? Get hold of me on listed here only make sure you.
