SD Series
Description
SD-series Roller Shutter has all the features that ST-series Roller Shutter possesses except its hand chain pulley system and clutch assembly is separated from each other, and the brake tensioner is removed to consolidate the motor mechanism. Therefore, the clutch assembly housed independently from the pulley system actually enhances the durability of the components. In addition, the use of the DOUBLE ROW DISK BRAKE SYSTEM provides a more effort-saving, precise and steady break action than general break system.
