So with that said, standard rectangular shutters can consist of one or more panels hinged in a variety of configurations. Single panels can be individually hinged, or two panels may be hinged together in a bi-fold design. All bi-fold panels are butted together and have a butterflied butt hinge attached on the back of the stiles. Maximum width for 2ea panels bi-fold poly shutters, 2L or 2R is 42” and 48” for basswood shutters.
Remember, when thinking about your panel height we recommend that panels over 96” in height have a divider rail, so that louvers will not need to be hand pressed to close. Additionally, panels over 96” in height require a divider rail to ensure structural integrity.
One last thing , bi-fold panels (2L 2R) without a track system can only span 96” for basswood shutters and 84” for poly shutters.
