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.
