This is a classic piece of redneck engineering. 1" sch 40 PVC pipe; adhesive backed foam; machine screw and lock nut; two wire ties and scrap plastic. And it works.
I originally had it mounted through a hole I cut (burned) in the side of the left pocket and took it out and put it into the slot provided for the stripping apron on the FishCast LCS4. I will likely return it to pocket side mount. I did back into a bridge support and break the tip on my 3 wt. You might want to consider something a design with 15 - 30 deg. above horizontal.
