Fish-On Compatible Fishing Rod Holder Mount for 1.5in x .25in Gunnel Rails on Aluminum Drift Boats

Print Model upside down and it will print with out supports.

This is a fishing rod holder mount that I made for my 1986 Alumaweld drift boat, it works with Fish-on rod holders like these: https://www.amazon.com/Fish-Twin-Pack-Holder-Mounts/dp/B001CJM3PS/ref=as_li_ss_tl?rps=1&ie=UTF8&qid=1527689516&sr=8-1&keywords=fish-on&refinements=p_85:2470955011&linkCode=sl1&tag=wremot-20&linkId=ccb94944b3e7e8aca01c508694e9d1fc

This allows you to mount to the gunnel rail with out drilling holes in your boat. It works great we have been using them for a while now. Once the slot is dropped over the gunnel rail the to bolts both pinch the rail but also pin it in place so that it can not fall off or slide away. This makes it real easy to relocate your rod holders in a hurry with out drilling new holes.

This might work on Willies, Koffler, newer or older Alumaweld and other aluminum drift boats with similar size gunnel rails. I plan on making some that fit a couple different boats so if you have one that you can send me rail dimensions for id be happy to adjust the design. This one is for use n a 1.5in x .25in (1-1/2X1/4in) or 7mm x 50mm Gunnel Rail.

These might also work with scotty style rod holders I have yet to confirm but it should be close.

This uses an M6x30mm bolts like these:
