Yes, it is the actual system. There is a rubber strip that covers the screw or bolt heads.
I got hold of the old Cascade folks who are the new Chinook Composites, Corp.. They still answer questions. Their answer was thru bolt on eight inch centers staggering top and bottom bolts, meaning there would be a bolt every 4 inches (one from the top and 4" to the one from the side). I'll not be able to do that in all places because I have deck beam ends on the shelf which will definitely get in the way in a lot of areas where the bolt holes will fall.
The system is really strong. The newer Cascades use the toerail as chainplates and don't have "real" chainplates like I do.
I planned to slather the whole thing with 5200 and let it ooze out so I get some really good sealing and adhesion.
Thanks very much for your help. I learn stuff every day on this forum thanks to folks like you, Gord and Alan.
I like your recommendation for fisheries supply. They are great!!
Kind Regards,
