Sliding Glass Door Closer

NSC-G Series

Self-Closing System for Glass Sliding Doors

The NSC-G series Sliding Door Closer is an innovative solution adding self-closing feature to your glass sliding door.
By utilizing highly durable pull spring device, the NSC-G series offers full-range self-closing function.
The door closes automatically from any position you release the door to the complete close position. The rotary gear damper provides safe and smooth soft-close feature at the end of door closure.


Dual Speed Control:
Both the self-closing speed and soft-closing speed are individually adjustable.

Its compact size and functional design allows any sliding doors to become self closing. Designed for door panels of either single, bi-parting and telescopic configuration.

NSC-G series is a highly reliable system securely tested for 500,000(NSC-C60V-G) and 1,000,000(NSC-C48-G) cycles.

Long service life:
A long lasting product life time is achieved by our cutting-edge technologies, employed in our compact yet robust rotary gear damper, fluid friction resistance and one-way clutch brake mechanism.

The only preparation needed before installation is to drill screw holes into the door frame and glass. After that, all parts/devices can be installed by a screwdriver from the front, easily and efficiently.

Non Handed:
The system can be used for both left and right hand sliding doors. It can be easily converted between left and right handing by a simple adjustment procedure.

Non Electric:
The system does not require electric power so that works anytime even during power outage.

With its unique fluid reduction gear mechanism, the system is also designed to assist in reducing the door opening resistance to achieve an easy and safe opening operation for all, including the elderly, small children, people of limited mobility and people who are otherwise carrying large packages or groceries.
