Installing Side folding Grille

Now that you’ve collected the tools you need and verified that the installation site matches the original specs, you’re ready to install your side folding door track.

This article is meant to accompany the your installation instructions, which will be a lot like these. We’ll review the steps and go into more detail, and explain how to avoid some common pitfalls.

Clearances

But first, a note about clearances for the path of the track. It’s critical that you observe the minimum clearances listed, especially in the pocket and around curves.

Pocket Clearnace Diagram

Minimum clearances (shown as ‘A’ in the diagram above) are:

  • For Slim Line 4 Inch doors: 2 ½”
  • For Standard 7 Inch doors: 4”
  • For Wide Body 11 Inch doors: 6 ½”

If you don’t observe the minimum clearance in the pocket, you risk damage to the door if users try to jam them in. If possible, try to provide a bit of additional clearance beyond the minimum, as it improves usability.

Your security grille is basically a giant metal curtain, secured from the top and free on the bottom (until locked). When users open and close the door, it tends to swing out at the bottom, especially around curves. Having that extra bit of room makes for a more convenient experience for the person who opens and closes the door every day.

Final Preparation Steps

1. File Track Edges Smooth

Filing Edges of Track Smooth

It’s important to ensure any cut edges on the tracks are filed as smooth as possible and there are no metal filings/burring remaining. You’ll need each section to fit flush to its neighbour.

This is essential to ensure the door doesn’t catch, and flows smoothly from section to section. Neglecting to do this one of the only issues our customers ever have with track installation, and it not only makes for a “bumpy ride” but it can mean your door doesn’t last its full lifespan.

2. Confirm Track Hole Size

The track comes with holes sized for the #10 x 2” screws we provide for typical installations in wood and steel headers. If your header is masonry, however, you may want to use the appropriate fasteners for your material.

We recommend keeping to a #10 x 2” screw size even if you need to change screw type. If you need to increase the mounting hole size in the track, however, you can use a drill. There should be no need to file the hole.

3. Mark Track Centreline Path

Path of chalk line

Snap chalk lines to mark the centre of your track as per the your specific installation drawing (provided with your delivery). Mark where the path emerges from each pocket and how it travels across the opening.

Installation

1. Install Curved Track Sections First

Installing track curves

Install any curved sections to ensure the layout works. After, you’ll be fitting the straight sections between them, starting with the pockets and working your way out.

Don’t forget to leave one section uninstalled so you can load the door into the track. It can be any section along the centre of the opening, as long as it’s long enough to hold the entire door. We find, however, that it’s easiest if you leave the section furthest from the pocket uninstalled.

2. Join Straight Sections of Track One By One

Straight sections of track come in 4’ and 8’ lengths, and where possible we provide longer lengths to reduce the number of joins.

Pins and bars

Each section of track has an alignment bar at the top and two pins at the bottom. These should be used to marry each new section of track to its previously installed neighbour. If needed, the pins can be moved from one end of the track section to the other. We also include extras with every door, just in case.

To join each section, first line up the track:

Fitting the track

Then join the track, ensuring the bar and pins on the new section fit the previously mounted section.

Fitting the track 2

The joint should be as square and flush as possible, or else the wheels on the door won’t flow smoothly.

Seamless track join

Once you’ve confirmed there are no gaps, screw the track section to the header using all of the pre-drilled holes.

No Lubricant is Needed

Please don’t add any lubrication of any kind to the track; the wheels have internal lubricant that will last the lifetime of the door.

We’ve found that additional lubricant actually reduces door smoothness over time as dust becomes trapped. It also reduces overall door lifespan.

Next: Loading the Door

Once you’re done installing all the track sections but one, you’ll be ready to load the door into the track. We’ll cover that in the next post.

If you run into any alignment problems with your track, sections can be removed and reinstalled if needed. If you run into any other questions or issues just call our expert Customer Service team at 1-800-663-4599.
