Bi-Folding Doors
33D Series Folding Door
The double-track version of our slim 33 Series profile.
Overview
The 33D Series brings the slimmer 33 Series stile to a double-track, fold-to-both-sides layout — a lighter-profile option where the opening needs to split the stack but doesn’t need our heaviest-duty hardware.
