Door Kits

1 I HAVE A CUSTOMER WITH A BIFOLDING  DOOR WITH CABLES THAT ARE A SNARLED MESS. I WOULD LIKE A PARTS BREAKDOWN SO I KNOW WHAT TO CALL THE VARIOUS PARTS. ALSO, IS IT POSSIBLE TO CONVERT THIS DOOR BY ANOTHER MANUFACTURER  TO A SCHWEISS STRAP LIFT? I HAVE WORKED ON SEVERAL OF THEM AND LIKE THEM BETTER THAN CABLES. THANK YOU.

2 Bi-fold door: Does price include vertical column and header or is that locally procured? If there are heights and widths that if you stay lees than the is considerable savings I would like to know that info. Door height I want 17 foot of clearance what ever door height needs to be to achieve that.  Do you have an install team? And is price quoted installed? Is the steel building manufactures that a familiar what the building needs to be for the door? Is the latch strap system upgrade going to be cost a lot compared to if I decide to start with a latch strap?   Thanks Paul
