Hey, not to be a stick in the mud, but I heard somewhere here on the forum that people weren't happy with the quality of Happ's t-molding compared to other companies such as t-molding.com or GGG. You might just want to do a simple search before striking up a deal. I haven't tried any other t-molding than GGG's, so I'm no expert,
Cheers,
