They were one of the first to come out with thick 1012 trays that last for years instead of a year or two.
Nice looking aluminum extrusion for the track and I dealt with aluminum extrusion for 25 years in the sign business so I know good from bad.
The wiggle wire is not only plastic coated the full length but they put an extra coating on the ends where it could poke through the plastic, plus they make it red for high visibility which helps the human aspect of dealing with it. (you'll put your eye out kid)
Now I need to check the budget again to see if I can buy top plastic tonight or the 3rd of September.
