Foam Core Sceen Spline

I am a professional screen repair company(Screensmith). I am looking for a new company to buy foam core spline in 5 to 7 different sizes. I have found that this spline is much more versatile than vinyl spline. It produces a much smoother result and causes less wear and tear on shoulders and elbows etc.I researched your website and was only able to find the spline in 25' increments. I would like to buy the spline in approxiametely 1000' rolls. Is there anything you can do to accommodate this request? It would be greatly appreciated! Thanks, James Thatcher
