After several years I have dropped my UL service. This year alone i have in excess of $4,000.00 in fees. I have had to purchase my own "Certified Calibrated" measuring tools so my inspector could measure the thickness of the aluminum sheeting that I used. The minimum I use is .040 and UL 48 requires a minimum of .020. If the inspector can't visually inspect & tell the difference between these measurements he should have to supply his own tools to tell the difference. I know it is whining over something that trivial but it still bothers me. The towns in my area don't require UL listing so it doesn't give me any advantages to "List" my product. It increases my cost but not my competitions costs. My product meets and exceeds UL 48 guidelines and always will. Now I don't have UL fees to increase my costs.
