Commercial rolling steel. Atlas door. Slats measure 2.5" tall and 12' 4 and 3/4" wide. Pics of slats that are damaged, bottom bar, and endlocks are on file. Video of site to be reviewed by Tony or Joel. Alternating endlocks on door, unsure if stamped or cast. Will need estimate put together and follow up with customer. Bottom bar outside is 12' inside measures 11'10.5" but the inside one has been notched to that size so most likely is was originally 12' also.
