✅ How to Fit Replacement Vertical Blind Slats
…and ensure trucks & hooks are correctly aligned
1. Gather the trucks (carriers) to one end or both ends if split draw
Before attaching new slats, you need all the trucks together so the spacing resets correctly.
- Use the chain control that rotates the slats (not the cord that opens the blinds).
- Turn it until the hooks are all at the same angle, and stop when they are in line.
- Now pull the open/close cord to draw all the trucks fully to one or both sides.
This ensures:
- Even spacing when they draw out again
- No twisted or misaligned trucks
- The hooks all start at the correct orientation
2. Set the hooks to 90° (left or right)
Your hooks must all be facing either fully left or fully right, which is 90° to the track, visually you will see the full outline of the hook when looking forward.
✅ To do this:
- Slowly rotate the tilt chain until:
- All hooks line up perfectly sideways
- None of them are twisted or lagging behind
- If one looks odd, rotate the chain through a full cycle again.
Most tracks realign themselves if you run them through a full rotation.
Tip:
If your hook faces forward or backward, rotate again. Hooks should be side-on when attaching slats.
3. Attach the slats
Once hooks look consistent:
✅ Step-by-step
- Hold the slat at the top with the top pocket clip facing left or right.
- Position the slat’s hanger slot onto the hook.
- Give a very gentle pull to check it’s secure.
Repeat for all slats going left to right.
4. Open the blinds to space the trucks
When all slats are attached:
- Use the open/close cord to draw the blinds fully across the window.
- The trucks will automatically space themselves evenly.
- Then adjust the tilt chain to confirm the slats rotate cleanly.
✅ Troubleshooting
❗ Some hooks face a different direction
Run the tilt chain all the way around again until everything resets.
❗ Slats cross over each other
This means one truck is out of sync.
- Rotate fully until the misaligned hook corrects itself.
