Child safety is not optional. It is fundamental.
At DOSRON, our cordless systems are engineered to eliminate exposed cords and hazardous loops — reducing strangulation risks at the source. Every architecture is developed in alignment with key global child-safety standards:
- ANSI/WCMA A100.1(U.S. Window Covering Safety Standard)
- CPSC 16 CFR 1260(U.S. Federal Mandatory Cordless Rule)
- EN 13120(European Child Safety Standard for Window Coverings)
- AS/NZS 60335.2.97(Australia & New Zealand Safety Standard for Motorized Blinds)
Because protecting children is not a feature upgrade.It is the starting point of responsible engineering.

Frequently Asked Question about Dosron
Q1: Is this Cordless Spring Drive suitable for motorized zebra blinds?
No. This system is engineered for manual cordless zebra blinds. Hybrid motor-spring platforms use different control logic.
Q2: How many Spring Boxes should I use?
It depends on measured fabric + bottom rail weight and required drop. Use the selection table to choose model and quantity per Shaft.
Q3: Why is pre-winding required before installation?
Pre-winding stores initial energy so the system enters the intended force band immediately. The Pin locks the pre-tension state.
Q4: Can a stronger Brake solve drift if the spring is mismatched?
Not reliably. The Spring Box defines the force band; the Brake only governs motion within it. Correct selection comes first.
Q5: Can different Spring Box models be mixed on one Shaft?
Yes, but only with proper load calculations to keep force distribution stable across the full travel.
