The Scotty Rail Mount Adapter 242 fits 7/8" & 1" diameter round rails, and 1" square rails. The Scotty Rail Mount Adapter 242 is ideal for mounting all Scotty post mount rod holders to certain types of railing. Works with a Scotty No. 241 side /deck mount and includes stainless steel fasteners.
Excellent . solid construction and fit 1.25 inch rail perfectly
Looks like a well made product and would work great with up to 1" tubing (although the package states that the hardware included is for 7/8" tubing). I read on another forum that it would fit around the Hobie Sidekick Tubing (which is the same tubing the paddles are made from) but it does not work. I will find a use for these adapters somewhere. My order shipped very quickly. Great Outfitter!
