Amazon.com: Ogrmar 2PCS Fishing Rod Holder Rod/ Ship Yacht Fishing Rod Frame Portable Lightweight and Rugged (White) : Sports & Outdoors

I had a rod holder that held 3 rods. I added one of the Ogrmar rod holders to each side of my original holder. Now I have a place for 5 rods. They matched my original rod holder and make it look like it was made that way!

Effectively a purpose designed segment of plastic pipe. The edges were the pole sits have a sort of seam on it, elliminating potentially sharp edges(dirty knuckle busters). Holes lined up with the mounts making it easier to attack. Standoffs around the holes guaranteeing a quality fit.

Good for the price but you need to go buy stainless hardware to mount it.
