Follow the typical practice, as shown in Step Attaching Hinges and Strut To Intermedi-
ate Section(s) prior to installing the long struts and upper hinge leafs to the lower rail of the
section(s).
With assistance, position a long strut over the upper hinge leaf and over the bottom rail of the
Intermediate section. Center the long strut from side to side, as shown.
