Albert Barnwright’s Trusted Guide
Installing a CHI residential overhead door might seem like a big lift, but with the right mindset, a good Saturday, and the proper instructions, you can get it done with confidence. I’ve always said that good prep and attention to detail can save you from headaches down the road—and that couldn’t be truer than when you’re setting up a garage door.
So let’s walk through this job together, the way I would if I was standing there with you, wrench in hand.
NOTE – This guide walks you through installing a CHI garage door using standard lift tracks. If your setup involves reverse angle mount tracks, this process won’t cover it. And remember, always follow the manufacturer’s instructions that come with your specific door kit. That paperwork is gold. It’s tailored for your model and keeps your install safe, correct, and under warranty.
Getting Started Right – Prep Your Space
Clear the Workspace
Before you even pick up a tool, you’ve got to clear the area. Move your vehicles out onto the driveway or the street, and make sure the front half of your garage is free from bins, tools, or anything else that could get in your way—or get damaged.
And please—this is a grown-up job. These doors are heavy, and the tools can be dangerous. Make sure kids and pets are safely out of the way the entire time.
Measure the Opening
Grab your tape and check the width and height of your garage door opening. Now take those numbers and match them up with the label on your CHI door kit. Usually, that info is on the box or shipping paperwork. You’re checking for:
- Model number
- Door size
- Insulation type
- Spring type (CHI uses torsion springs only)
- Track type (standard vertical and horizontal only—not reverse angle)
Verifying this upfront keeps you from finding out the hard way that something doesn’t fit.
Tools and Materials You’ll Need
Bring These Tools
- Socket wrench set (various sizes)
- Flathead and Phillips screwdrivers
- Power drill with assorted bits
- 4-foot level (not optional—critical)
- Tape measure
- Hammer
- Locking pliers or C-clamps
- Step ladder or scaffolding
- Safety glasses and work gloves
What Comes in the Kit
- Door panels (also called “sections”)
- Vertical and horizontal track assemblies with mounting brackets
- Torsion spring system
- Hinges and rollers
- Cable drums, pulleys, and cables
- Fasteners (bolts, lag screws, and nuts)
Handy Tip – Before you open the box, double-check your tools. You don’t want to find yourself on the roof of a ladder without the right bit in your drill.
Step-by-Step – Installing Your CHI Garage Door
1. Install the Bottom Panel
The bottom panel is the foundation for everything else, so take your time here.
Unwrap and inspect it.
Center it in the garage opening so it rests flat on the ground.
Use your level to ensure it’s perfectly horizontal. If your floor’s uneven, use shims until it is.
This step affects how straight and smooth your tracks will run, so don’t rush it.
2. Attach the Vertical Tracks
These tracks guide the rollers and keep everything aligned vertically.
Start by securing the jamb brackets to your door frame.
Position the vertical tracks against these brackets, leaving about a ¼-inch gap between the track and door panel.
If the garage floor slopes, mount the higher side first.
Use your level to make sure both tracks are plumb and even. Adjust at the bottom if necessary.
3. Assemble and Stack the Door Sections
Time to build upward.
Insert rollers into the hinges of the first panel.
Set the next panel on top and temporarily secure it—some folks use a nail or a “Z” bracket.
Make sure the door face is lined up nice and flush with the jamb trim.
Connect the sections using the hinges and install the rollers into the tracks as you go.
Repeat until all your panels are stacked and secure.
Handy Tip – As you’re stacking, don’t force the panels. If something doesn’t feel right, it probably isn’t. Step back and recheck alignment.
4. Install the Top Brackets
The top fixtures help the door follow the curved part of the track.
Measure 2 inches down from the top of the door and mark it.
Pre-drill your holes, then mount the fixture with lag screws.
Make sure the roller fits into the curve of the horizontal track smoothly.
5. Set the Horizontal Tracks
These are the tracks that stretch along the ceiling.
Connect the horizontal tracks to the vertical ones using the included brackets.
Temporarily support them with steel wire or clamps until secured.
The tracks should slope upward slightly—about 1/8 inch per foot of door height.
Attach rear hangers near the header to support the track ends.
Use your tape measure to check diagonals and make sure everything’s square and evenly spaced.
6. Install the Torsion Spring System (Caution Zone)
This step is no joke—torsion springs are under serious tension. If you’re unsure, stop here and call in a pro.
With the door shut, assemble the spring shaft, end bearing plates, and cable drums.
Match left-hand and right-hand drums (they’ll be labeled or color-coded).
Bolt the bearing plates to the horizontal tracks.
Carefully wind the springs to the specified tension.
Run the cables through the pulleys and drums—no slack allowed.
Handy Tip – There’s no shame in calling a professional for this part. A spring under load is nothing to mess with.
7. Final Adjustments and Testing
Tighten every bolt, screw, and bracket one more time.
Open and close the door manually. It should glide smooth and hold itself about halfway open without slamming shut.
Adjust the spring tension if needed.
Make sure the seals sit flush at the bottom and sides.
Keep It Running Smooth – Ongoing Maintenance
A properly installed CHI door should last you for years—but only if you take care of it:
Lubricate the rollers, hinges, and springs a couple times a year.
Check the cables for fraying or wear.
Clear debris from the tracks regularly.
Recheck balance if the door starts dragging or feels heavy.
Handy Tip – A little upkeep saves a lot of money. Just like greasing a tractor before planting season—it’s better to stay ahead of trouble than chase it down later.
Should You Call a Pro?
This guide gives you the full picture, but it’s not a substitute for skill or experience. If you’re unsure at any point—especially during the torsion spring install—it’s best to call in a CHI-authorized installer. They’ve got the training to do the job safely and keep your warranty intact.
