Proper installation of garage door components is crucial for ensuring the functionality, safety, and longevity of your garage door system. In this guide, we will walk you through step-by-step procedures for installing extension spring cable sets, pulleys with straps and bolts, door roller safety cable kits, and door bottom seal hinges.

Extension Spring Cable Set and Pulley with Strap & Bolt Installation Procedures:

Step 1: Disconnect Power and Secure Door

• If you have an electric operator, disconnect the power supply and moving arm to operate the door manually.
• Open the door fully and secure the bottom roller in the track using a "C" clamp or locking pliers.
• Do not replace more than one cable at a time.

Step 2: Remove Old Cable

• Pry open the "S" hook attached to the overhead support bar and pull the cable forward to release tension.
• Disconnect the "S" hook and remove the loop end of the cable from the door bottom.
• Install the new cable by hooking the loop end over the cable stud and threading it over the pulleys.

Step 3: Attach "S" Hook and Check Tension

• Attach the "S" hook to the cable connector and thread the cable through the holes in the connector.
• Ensure both cables have equal tension. Adjust cable position in the connector if necessary.
• Close the "S" hook end with pliers, remove the clamp, and check door operation.

Pulley with Strap & Bolt Installation Procedures:

Step 1: Disconnect Power and Secure Door

• If you have an electric operator, disconnect the power supply and moving arm for manual operation.
• Open the door fully and secure the bottom roller in the track with a "C" clamp or locking pliers.
• Do not replace more than one pulley at a time.

Step 2: Remove Old Pulley

• Pry open the "S" hook attached to the overhead support bar and pull the cable forward to release tension.
• Remove the nut holding the pulley to the strap or upper support bar.
• Slip out the old pulley and install the new one in the same location.

Step 3: Install New Pulley and Check Tension

• Install the new pulley in the same location, ensuring it is the same size as the old one.
• Tighten the nut securely, install the cable, and attach the "S" hook in the same location.
• Ensure both cables have equal tension.

Safety Cable Kit for Spring Containment and Door Bottom Seal Hinges Installation Procedures:

Important Note:

• If your door has a torsion spring coiled around a tube or shaft above the door opening, do not attempt to replace the bottom roller. Call a professional door service firm.

Step 1: Safety Cable Installation

• Open the door fully and block the bottom roller in the track with a "C" clamp or locking pliers.
• Attach the safety cable to the rear track support bar just above the upper spring.
• Thread the plain end around the support bar, through the looped end, and through the spring.

Step 2: Run Safety Cable

• Run the safety cable along the outside of the pulley (away from the door) and install it through the forward-most hole on the overhead support bar.
• Install the cable clamp and tighten nuts alternately until secure. The cable does not need to be tight.

Step 3: Ensure Proper Placement

• There must be enough room for the spring pulley to ride completely forward when the door is closed.
• Close the door after removing the track clamp to ensure the safety cable does not bind. Adjust if necessary.

Bottom Roller Replacement on Extension Spring Door:

Step 1: Disconnect Power and Secure Door

• If you have an electric operator, disconnect the power supply and moving arm for manual operation.
• Open the door fully and secure the bottom roller in the track with a "C" clamp or locking pliers.
• Do not block the roller you intend to replace.

Step 2: Remove Old Roller

• Pry open the "S" hook attached to the overhead support bar and pull the cable forward to release tension.
• Disconnect the "S" hook, release tension, and let the spring hang down.
• Remove the loop end of the cable from the cable stud on the door bottom.
• Remove bolts attaching the bracket to the door and slip the roller out of the track.

Step 3: Install New Roller

• Install the new roller onto the bracket, slip it into the track, and install bolts. Tighten securely.
• Reconnect the cable to the bottom bracket, pulleys, and "S" hook. Ensure both cables have equal tension.

Upper Roller Replacement - All Doors:

Step 1: Close and Lock the Door Securely

• Do not replace more than one hinge or roller at a time.

Step 2: Remove Old Roller

• Remove the bolts attaching the hinge to the door frame.
• Slide the hinge off the roller and slip the roller out of the track.

Step 3: Install New Roller

• Insert the roller into the outer tube of the new hinge, ensuring the number on the hinge bracket is upright.
• Slip the roller into the track and position the hinge over the old hole.
• Install carriage bolts and tighten nuts securely. Check for proper operation.

Wood Door Bottom Seal Installation Procedures:

Step 1: Electric Operator and Door Securely Blocked

• If you have an electric operator, disconnect the power supply and moving arm for manual operation.
• Open the door fully and block the roller in the track with a "C" clamp or locking pliers.

Step 2: Install Rubber Weather Seal

• Remove old weather-stripping and old nails or screws.
• Begin installing the new rubber at one end, overlapping 1/2" to 3/4" from the edge of the door.
• Install the first nail or screw and align the next section on the door bottom.
• Install the second fastener approximately 6" to 8" over; do not overstretch rubber.

Fiberglass Door Bottom Seal Installation Procedures:

Step 1: Electric Operator and Door Securely Blocked

• If you have an electric operator, disconnect the power supply and moving arm for manual operation.
• Open the door fully and block the roller in the track with a "C" clamp or locking pliers.

Step 2: Install Rubber Weather Seal

• Remove the old rubber by pulling it out of the channel.
• Begin installing the new rubber by feeding it into the slots.
• Pull the rubber down in short sections, feeding as you go, until fully installed.
• Do not cut excess at this time. Wait one day for the rubber to stop shrinking, then re-adjust its position for full coverage.

Additional Notes:

• Always replace only one roller or hinge at a time to avoid disrupting the balance of the door.
• Consult professional door service if your door is equipped with a torsion spring coiled around a tube or shaft above the door opening.
• Follow manufacturer's specifications and read directions completely before starting any repair job.

By following these detailed installation procedures, you'll ensure a smooth and successful installation of extension spring cable sets, pulleys, safety cables, door bottom seals, and other essential garage
