I reached out to AdWagon to see if they would offer the upper wall/ceiling L-track portion of their kit (6 length-wise runs) as an al a cart item. Their initial response is that you'd have to buy their full kit (semi stripped) that would still include all the panels etc for $9K. I'm curious what level of demand there would be if they did offer it separately at a reasonable price to incentivize them/incentivize me to develop a kit solution beyond a one off for myself. Note the cost of L-track included itself would be about $1000 just to start (12 96" lengths), so something higher than that for the mounting system design/material/fab. Please select the MOST you might be willing to pay.
