Critical Installation Tip for Middle-Open Motorized Vertical Blinds with Spliced Track

Introduction

Motorized vertical blinds offer modern convenience and style—until a small oversight during installation causes big headaches. If you’ve purchased middle-open motorized vertical blinds with a spliced track, there’s one critical step that’s easy to miss but vital for smooth performance.

Forget this step, and you may face issues like stuck belts, jerky movement, or a completely unresponsive system. In this guide, we’ll walk you through the key installation checkpoint to keep your blinds running flawlessly.

The One Step You Can’t Afford to Miss

When assembling a spliced rail system, it’s essential to secure the carriage and slider inside the track with a screw. If this screw is not tightened properly, the motorized track won’t be able to drive the carriage—and the belt will get stuck.

🔩 What Is This Screw and Where Is It?

Inside one side of the spliced track, you’ll find:

A slider (which holds the vertical blind vanes)
A carriage (which connects to the drive system)

These two components must be fixed together using a small screw included in your installation kit.

Step-by-Step Guide

✅ Before Installing the Track

Lay the spliced track on a flat surface.
Locate the slider and carriage inside the track.
Use the provided screw to secure them firmly together.

🛠️ How to Do It

Insert the screw through the designated hole in the carriage into the slider.
Tighten just enough to hold firmly—do not over-tighten.
Gently test the movement by hand to ensure the carriage and slider move as one unit.
