There are two types of end bearing plates: supported and unsupported. The supported end bearing plate is mostly being used for standard systems; 12 inches and up clearance between top of door opening to the ceiling. The supported end bearing plate is mounted to the flag bracket, to the punch angle of the horizontal track and to the header/jamb. The unsupported end bearing plate is mostly being used for low clearance systems; less than 12 inches clearance between the top of door opening to the ceiling. The unsupported end bearing plate is mounted to the flag bracket and/or to the horizontal track punch angle only.
