Good Morning All,

Installing a set of trackless bi-folds in an opening that currently has
carpeting. I could pull back the carpeting but Id rather not.
Looking ahead I can imagine shimming the doors into the jam
could be a problem with a carpet surface.

Im thinking of laying some masonite to give the shims something a
little firmer to wedge against. Could perhaps then wedge the top flush up
against the head jam rather than shooting for gap...

Any one whose dealt with this before care to share there technique? The books
Ive got dont get into details like this.

TIA
