header wall and close the door.
Mount the front wall bracket with its lower
edge approximately 1/2" -1" above the
mark showing the highest point of travel and
centered on the vertical center line.

counterbalance, hold the wall bracket's
bottom edge typically at 1/2" - 1" (room
permitting) above the torsion spring center
bracket and centered on the vertical line, see
illustration.
Mark the two mounting holes and pilot drill
