How to Splice a Jason Motorized Curtain Track: A Step-by-Step Guide for All 4 Configurations

If your window is wider than a single track section, or you're setting up a center-opening system, you'll need to splice two track sections together before you mount anything to the wall or ceiling. It sounds intimidating, but the Jason Custom Motorized Curtain Track is engineered so the splicing and master carrier assembly can be done on a flat surface with just a hex key — no special tools required.

Lay your track sections out on a clean, flat surface — a hardwood floor or long table works well — and give yourself enough room to work along the full length of both sections.

Because Jason tracks support four different curtain styles and draw configurations, the exact sequence changes slightly depending on what you're building. This guide walks through all four: Pleat Runner Single Open, Pleat Runner Center Open, Ripple Fold Runner Single Open, and Ripple Fold Runner Center Open. Follow the section that matches your setup.

Part 1: Pleat Runner — Single Open (One-Way Draw)

This is the simplest configuration: one curtain panel that draws to a single side, ideal for a clean, minimal look.

Before you start splicing, do a quick visual check:

• Make sure every eyelet runner is seated inside the track channel. If any have popped out, gently press them back in.
• Confirm the master carrier and drive belt are sitting correctly in the channel. If either has slipped out, reinsert it before moving on — trying to splice around a displaced belt will only cause headaches later.
• If the drive belt is sitting outside the channel anywhere along its length, pull it free and reseat it properly. A belt that rides outside the track profile is one of the most common causes of jamming and resistance once the system is motorized.

Once everything is seated correctly, splice the track:

1. Lay out the track sections for splicing, positioning them end to end with the channels aligned.
2. Loosen the screws on the master carrier arm assembly so the housing can be opened.
3. Remove the locking clip plate from the master carrier.
4. Bring the two master carrier bodies together, joining the halves from each track section into a single unit.
5. Insert the locking clip plate to hold the two carrier bodies in position.
6. Retighten all the screws securely. Don't rush this step — a loose master carrier is the most common cause of a rough or uneven glide later on.
7. Check the glide. Slide the master carrier by hand along the seam to confirm it moves smoothly across the join.
8. Attach the track connector bracket over the splice joint on the outside of the track.
9. Tighten all the set screws on the splicing bracket using the hex key, working along its full length.
10. Do a final traverse test, running the master carrier back and forth across the spliced section to confirm the assembly is complete and snag-free.

Part 2: Pleat Runner — Center Open (Split Draw)

This configuration uses two panels that part in the middle — a classic look for wider windows. The splicing steps are nearly identical to the single-open version, with the master carrier now positioned at the center of the track rather than at one end.

Before you start, run the same checks — with a center-open system, check both sides of the centerline:

• Verify that both master carriers and the drive belt are properly seated. If any component has slipped out, reinsert it into the track before continuing.
• Ensure the drive belt is seated correctly within the track profile. If it stays outside the channel anywhere, it will cause jamming or resistance — remove it and reinstall it correctly.

Now splice the track:

1. Lay out the track sections for splicing, aligning the channels at the center point.
2. Loosen the screws on the master carrier arm assembly.
3. Remove the locking clip plate from the master carrier.
4. Bring the two master carrier bodies together at the center point.
5. Insert the locking clip plate.
6. Retighten all the screws securely.
7. Attach the track connector bracket over the splice joint.
8. Use the hex key to tighten all set screws on the splicing bracket.
9. Test the master carrier traverse movement across the spliced section — for a center-open system, check that both carriers move symmetrically away from the center.

Part 3: Ripple Fold Runner — Single Open (One-Way Draw)

Ripple fold curtains use a continuous string of runners connected by a cord, which creates the signature soft "S" wave. Because the runners are strung together, this configuration adds a couple of extra steps for threading and connecting the runner string to the master carrier.

Before you start, run the same checks:

• Verify that both the master carrier and drive belt are properly seated. If any component has slipped out, reinsert it into the track.
• Ensure the drive belt is seated correctly within the track profile. If it stays outside the channel, it will cause jamming or resistance — remove it and reinstall it correctly.

Now splice the track and connect the runner string:

1. Lay out the track sections for splicing.
2. Hold the ripple fold runner string at the point where it will meet the master carrier.
3. Thread the runners through the track channel, feeding the string along its length.
4. Insert the runner-to-carrier connecting joint into the master carrier notch — this is the small fitting that links the continuous runner string to the carrier itself.
5. Loosen the screws on the master carrier arm assembly.
6. Remove the locking clip plate from the master carrier.
7. Bring the two master carrier bodies together.
8. Insert the locking clip plate.
9. Position the raised screw section against the joint to lock the runner connection in place.
10. Retighten all the screws securely.
11. Test the traverse to confirm the master carrier and ripple fold runners move together as a single unit, without the string dragging or catching.
12. Attach the track connector bracket over the splice joint.
13. Use the hex key to tighten all set screws on the splicing bracket.
14. Run a final traverse test across the spliced section to complete the assembly.

Part 4: Ripple Fold Runner — Center Open (Split Draw)

The center-open ripple fold configuration is the most involved of the four, because you're connecting the runner string to the master carrier on both sides of the centerline. Take it side by side and don't rush the second connection — it's easy to assume it's identical to the first, but it's worth double-checking each joint individually.

Before you start:

• Prepare the track sections for assembly, laying them out with the channels aligned at the center point.
• Ensure the drive belt is correctly seated inside the track channel. If it's sitting outside, remove and reinstall it to avoid jamming.
• Keep in mind that before assembly, the ripple fold runners and master carrier will not move together — that's expected at this stage, since the connecting joint hasn't been made yet.

Now connect the first side:

1. Loosen the screws on the master carrier arm assembly.
2. Place the runner-to-carrier connecting joint into the master carrier notch.
3. Remove the locking clip plate from the master carrier.
4. Bring the two master carrier bodies together and insert the locking clip plate.
5. Place the runner-to-carrier connecting joint into the notch on the master carrier.
6. Position the raised screw section against the joint to secure the connection.
7. Retighten all the screws securely.
8. Test the traverse to confirm the master carrier and ripple fold runners move together smoothly on this side.

Then repeat on the opposite side:

9. Assemble the runner and carrier connection on the opposite side using the exact same method — thread the runner string, seat the connecting joint, position the raised screw section, and retighten the screws.
10. Test the traverse again, confirming smooth, matched movement on both sides of the center.
11. Attach the track connector bracket over the splice joint.
12. Use the hex key to tighten all set screws on the splicing bracket.
13. Run a final traverse test across the spliced section on both sides to complete the assembly.

A Few Tips Before You Mount the Track

• Test before you install. Every step above happens on the floor for a reason — it's far easier to fix a stiff glide or a loose clip plate now than after the track is on the ceiling or wall.
• Don't skip the belt check. A drive belt that's even slightly outside the channel is the single most common cause of resistance once the motor is running.
• Keep your hex key handy. Every configuration ends the same way: connector bracket on, set screws tight, final traverse test. Getting into that rhythm makes the rest of the install go quickly.

Once your track is spliced and gliding smoothly end to end, you're ready to mount it and attach the motor — see our motorized curtain track installation guide for the next steps.

Frequently Asked Questions (FAQ)

Q: Why did my Jason track arrive in separate sections that need splicing at all?
A: Any track longer than 82 inches is spliced into sections for shipping. If your track came in one piece, you can skip straight to mounting — the splicing steps above only apply once you're joining sections back together.

Q: What hardware do I need for the splicing bracket, and is a hex key included?
A: The set screws on the connector bracket are M4 size, and a hex key comes with your installation hardware, so you won't need to source anything extra just to complete the splice.

Q: I ordered a Double Track (for sheer and drape layers). Do I splice both tracks the same way?
A: Yes. Each track in a double-track set is spliced independently using the same process for its runner type and open configuration — just repeat the relevant part of this guide for each track.

Q: Will splicing the track myself affect the warranty?
A: Curtarra backs the motor and controls with a 5-year warranty against manufacturing defects. Following the splicing and installation instructions as provided won't affect that coverage — the warranty is about material and workmanship, not about who assembles the track.

Q: How much weight can the spliced track and master carrier actually support?
A: The track has a maximum weight capacity of 99 lbs, so as long as the master carrier is properly clipped, screwed, and tested for smooth glide as described above, it's built to carry substantial curtain panels without strain.

Q: What if I'm not confident doing this myself?
A: The track ships fully assembled and pre-programmed, with a printed instruction manual and the video walkthroughs referenced throughout this guide, so most homeowners can complete it as a DIY project. If you'd rather not tackle it yourself, a local handyman or curtain installer can also follow these same steps.
