Custom Top Down Bottom Up Cordless Blind Fittings for Child Safety Window Coverings

Product Overview

The Custom Top Down Bottom Up Cordless Blind Fittings for Child Safety Window Coverings are designed
as a modular hardware platform for shade manufacturers. Instead of exposed cords or chains, a
spring-balanced cordless mechanism hidden in the headrail and bottom rail controls the shade position
from both directions:

• Top-down: Lower the top rail to bring light in while maintaining privacy below.
• Bottom-up: Raise the bottom rail in a familiar, smooth cordless motion.
• Hold-at-any-position: Tuned torque and friction keep the shade steady at intermediate heights.

This fittings set targets OEM/ODM brands needing a ready-to-industrialize cordless solution that meets
modern child and pet safety requirements and is suitable for residential and light-commercial projects.

How to Specify Your Custom Fittings

To size and configure the Custom Top Down Bottom Up Cordless Blind Fittings for Child Safety Window Coverings
for your project, please prepare:

1. Blind type – Honeycomb/cellular, Roman, pleated, etc.
2. Typical width × drop – Min / max sizes you plan to offer.
