This past Sunday at BPS, I was closely looking at the Grizzly's T-Rail system.
and also pondering of how to implement it on my 1988 bass boat.
Then I remembered using it in a Track Light system back in the day.
If I remember correctly, the track came in different lengths up to 10'.
I would much rather have a T-Track on my gunwales than a bunch of individual clip-on stuff.
Am sure the big box electrical stores would have it. Grainger, City Electric, Graybar,
MSC Industrial, McMaster-Carr, etc etc etc.
There is nothing wrong with butt-joining the ends of 2 or 4' sections to make your project work.
The extruded aluminum is easily bendable to fit the contours of the boat and still have the T-Slot holding power in place.
Yep - in my mind, that right there will WORK !!!
Just did a quick look on McMaster-Carr website and found this.
