Another update: When I tried to contact the Innovation Fiberglass to get a dealer list, I learned that they are no longer in business.

Oh, well, I'll just have to hope a local A.R.E. or Leer dealer might help if I ever need to replace a window or door on that orphaned Innovation cap. In the meantime, I'll be super-careful with it! 2010feb01(17:57)-sls
