NOTE: Refer to Package Contents / Parts Breakdown, to determine which End Bearing Brackets you have.

NOTE: Prior to fastening end bearing brackets into the door jamb, pilot drill using a 3/16” drill bit.

IMPORTANT: Right and left hand is always determined from inside the building looking out.

NOTE: Depending on your door’s configuration you may have to break the end bearing brackets apart.

NOTE: End bearing brackets are right and left hand.

Attach the left hand end bearing bracket through either the end bearing bracket’s upper or lower slots to the left hand horizontal track angle using (2) 3/8” - 16 x 3/4” truss head bolts and (2) 3/8” - 16 nuts.

IMPORTANT: The end bearing bracket’s lower slots are used on doors with 12” radius track; the upper slots are used on doors with 15” radius track.

Secure the top of the end bearing bracket to the jamb using 5/16” x 1-5/8” lag screw(s). Repeat the same process for right hand side.

NOTE: Refer to Package Contents / Parts Breakdown, to determine which Center Bracket(s) came with your door.

NOTE: Prior to fastening center bracket(s) into the door jamb, pilot drill using a 3/16” drill bit.

NOTE: Refer to Package Contents / Parts Breakdown, to determine if your door came with a coupler assembly. If your door came with a coupler assembly, the mounting surface needs to be a minimum of 17” wide. The two center bearing brackets will need to be spaced 12” to 14” apart at the center of the door, as shown.

NOTE: If your door came with (4) springs, each of the outer springs mounting surface will need to be a minimum of 3” wide.

NOTE: If needed, measure the diameter of your springs. If you have a one piece shaft with 3-3/4” diameter springs, they do not share center brackets and do not have a coupler as- sembly.

First, locate the center of the door. Mark a vertical pencil line on the mounting surface above the door, at the center. Measure from the center of the bearing, in one of the end bearing brackets, downwards, to the top the door. Using that measurement, measure that distance upwards from the top of the door to the mounting surface and mark a horizontal pencil line which intersects the vertical pencil line.

If your door did not come with a center coupler assembly or Torsion Springs less than 3-3/4” ID: Mark a vertical pencil line on the mounting surface above the door, at the center. Align the edge of the center bracket with the vertical pencil line and the center of the center bracket with the horizontal pencil line; this is to ensure the torsion shaft is level between the center and end bearing brackets.

NOTE: On some single spring doors, the single spring can be longer than half the opening width. If your spring is longer, then the center bracket must be mounted off center for the spring to fit properly. Measure spring length to determine appropriate center bracket location.

If your door did come with a center coupler assembly or 3-3/4” ID Tor- sion Springs: Mark a vertical pencil line on the mounting surface above the door, at the center. Split the difference up and position the (2) center bearing brackets apart from each other. Mark two vertical pencil lines, one for each center bearing bracket onto the mounting surface above the door.

NOTE: If your door came with a center coupler assembly or if it utilizes 3-3/4” springs, the springs will not share a center bracket.

NOTE: If your door has (4) springs, split the distance between the center of the door and the end bracket on each side to locate the intermediate center brackets.

Attach each of the center bracket(s) to the mounting surface, using (2) 5/16” x 1-5/8” lag screws and (1) 5/16” x 2” tamper-resistant lag screw.

IMPORTANT: Use a 5/16” x 1-5/8” tamper-resistant lag screw instead of the 5/16” x 2” tamper-resistant lag screw if mounting surface is mounted over masonry. Tamper-resistant lag screw must be attached through the bottom hole of the center bracket(s).
