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.
