Attwood 5016-3 Heavy-Duty Rod Holder Extension, Black, Up to 6 Inches, Mounts to Round or Square 7/8 to 1 1/4-inch-Diameter Rail

Which it came in white. I had to paint them but all in all they are great.

I have older Robert's rod holders and these extensions work perfectly.

Was going to replace Atwood rod holders because I needed the extensions. Searched Amazon and thought it was a long shot… by golly found them and saved money by not having to buy new rod holders. Work great!!

Gives my long Handel rods more room to get in and out of the rod holder.

It seems to fit well enough and seems sturdy enough.

by Marjorie's husband: I needed a way to mount a temporary VHF radio antenna on my boat and already had Attwood Rod holders. But the antenna needed a base and to be elevated. I was ready to sacrifice a rod holder but got on Amazon and started looking around and found this!! YEAH! Today I fit a 10 inch piece of conduit into the deep hole of this extension, after filling it with Marine Tex. then did the same for a 2 foot antenna extension and pushed it on the other end of the conduit. Let cure. Screw antenna into the glued antenna extension. Now I can stash the antenna under the gunwale rail while fishing, loading, or trailering then pop the antenna into one of the rod sockets while I'm underway. Seems quite sturdy. Might not be the original use intended but I'm confident it will work well for me. I've busted too many of the fixed or ratchet swivel mounted antennas and this will save me $$$.

Super strong, coming into dock and line was wrapped around it. Stopped the boat without breaking, still for piece of plastic think a little expensive

Alittle sloppy in the Bass pro shop rod holder mounts but works for what I wanted it for. Dad doesnt have to lean over to take rod out. Seems plenty heavy enough for catfishing which I use it for.
