Methods of forming and installing overhead support systems for movable partition systems

A method of installing an overhead support system for a movable partition system, comprising:

• forming an at least substantially straight elongated unitary body, comprising:
• forming a longitudinally extending and vertically oriented central beam;
• forming a pair of attachment flanges extending laterally from a top end of the central beam;
• and
• forming a pair of chain guide members extending laterally from the central beam vertically below the pair of attachment flanges, the attachment flanges of the pair of attachment flanges projecting laterally outward from the central beam beyond laterally outward ends of the chain guide members of the pair of chain guide members;
• and
• bending the elongated unitary body while applying a tensile force to the elongated unitary body resulting in tension within the elongated unitary body higher than a yield point of a material of the elongated unitary body;
• and
• inserting fasteners at least substantially perpendicularly through the attachment flanges of the pair of attachment flanges and at least substantially parallel to the central beam.
