How to Install a Clopay Garage Door Opener Bracket


Installing an opener on your Clopay steel garage door, requires installing a Clopay garage door opener bracket. The opener bracket spreads the force of the garage door opener across the top section of the door. This prevents the opener from damaging the top section. The opener bracket mounts on the center stile of the top section where the center hinges connect. A piece of pre-punch steel is necessary to help reinforce the top section and aid the garage door opener bracket. Pre-punch steel angle and Clopay door opener brackets are available at home improvement centers.

Things You'll Need

  • Tape measure
  • Hacksaw
  • Socket wrench set
  • Pencil
  • Six foot stick of pre-punch steel angle
  • Drill
  • 1/4-inch drill bit
  • 1/4-inch by 1/2-inch long bolts with washers and nuts (6)
  • Measure the height of the top section of the garage door with a tape measure. The garage door is a sectional and usually has four or five sections. The top section is the section that you mount the opener bracket. Transfer the measurement to the opener bracket. Measure from the bottom of the bracket to the top, marlking the measurement of the door section on the upper part of the bracket.

  • Cut the door bracket as necessary with a hacksaw. File the top edge of the bracket with a file to smooth over the cut edge. Cut a four foot piece of pre-punch angle iron with the hacksaw.

  • Remove the hex head screws securing the top of the center door hinge to the top section with a socket wrench. Most garage doors have a hinge in the middle of each door section joining to the next section. The bottom of the door opener bracket has holes that line up with the mounting holes of the hinge.

  • Position the door opener bracket over the center of the top garage door section with the lower holes of the bracket over the upper mounting holes of the center hinge. Mark the two upper mounting holes of the door opener bracket onto the door with a pencil. Center the piece of angle iron over the upper mounting hole so that the angle iron is even on both sides of the hole. Mark the end mounting hole on each of the angle iron to the door with a pencil.

  • Drill holes for the mounting bolts at the top of the door section with a 1/4-inch drill bit. Drill the holes for the opener bracket and the pre-punch angle iron. Place the opener bracket onto the center of the top section, lining up the mounting holes. Slide the pre-punch angle over the top of the mounting bracket, lining up the two end mounting holes and the bracket mounting hole. Insert a 1/4-inch bolt through the uppermost mounting hole for the opener bracket. Insert the bolt from behind. The bolt goes through the center stile of the door, the opener bracket and the pre-punch. Secure the bolt with a washer and retaining nut.

  • Insert the bolts through both ends of the pre-punch and the lowermost upper mounting hole for the opener bracket. Place washers and nuts over each bolt to secure. Place bolts through the back of the center hinge through the lower part of the opener bracket. Place washers and retaining nuts on each. Tighten all the bolt retaining nuts with a socket wrench. Install the door opener lower arm per the instructions with your garage door opener.

Tips & Warnings

  • Wood doors do not need opener brackets. Most wood doors require a carriage bolt that goes through the entire thickness of the door into the opener arm bracket.
