New generation metal core breaking system

Gear deceleration ratio 1:4 can be choose.

The low stop of the winder ensure the one way work,and the high precision linear winder ensures a line of lifting,the spacial leaf-driving structure,ensuring that system is smooth and stable and good air tight.

The new type metal core brake system and one-way used winder can be extended to automatic descent system.

4.5*6 loop chain and 5mm loop cord is available.

The no-load tension is less than 0.5kg,max weight is 15kg,and the rising tension is less thsn 4kg,which make the labor saving to 80%.
