Lingster, for Rod Holders we used
Vector Teknologies out of Richmond IL. They have since been sold, but their web site is http://www.naturevisioninc.com/vector/
We have four Rail Mount Rod Holders with 1 inch Clamps for Rail Mount items in Blue and Black.
We also have Single Spring-Loc Rod Holders with the Flip-Loc Upgrade, Dipsy Angles, 0 & 11.5 Degrees in Blue and Black for our Track Mounting System
Hope this helps.
