I'm looking for some T-Lock cap/railing or something similiar to mount on the sides of my boat for accessories. In my search the only source I could find was War Eagle Boats and didn't see where they were selling the cap/railing by the foot, but the accessories. Anyone know of a good source for accessory railing? Doesn't have to be T-lock.

Look up "T Slot Aluminum Extrusion" there are may types out there... find the one you like and go with it

Or better than that look up "Aluminum T Track"

Thank you for the info!!

Might want to consider mounting S Track instead. They have connectors you can install and remove without having to run them thru the entire length of the slot. Not that bad, until you have to get on the far side of something that's already in there.
