They look good, just need to make sure they won't turn to the side while pullin or when you have a big catfish hit your cranks. If they turn it's a good chance your rod will get pulled out of the holder.
Slabo is correct. If you can weld some kind of stop they would be even better. I have had several rods pulled overboard and it's a sickening feeling.
