Sugatsune Door Damper LDD-V

Sugatsune LDD-V Door Damper

The Sugatsune LDD-V Door Damper provides smooth and controlled soft closing for interior doors. Its concealed design keeps the mechanism hidden when the door closes, creating a clean and modern appearance. In addition, the damper reduces noise and helps protect doors from damage caused by slamming.

Smooth and Quiet Door Closing

The integrated damping mechanism activates during the final 10° of the closing movement. As a result, the door closes gently and quietly every time. Furthermore, users experience less impact on hinges and surrounding hardware, which helps extend the life of the door system.

Unlike many traditional door closers, the LDD-V allows doors to open with less resistance. Therefore, it improves comfort while maintaining reliable soft-close performance.

Easy Adjustment and Installation

The Sugatsune LDD-V Door Damper includes an adjustable closing speed, allowing installers to fine-tune the closing action after installation. Additionally, the counter plate offers 3-way adjustment, making door alignment quicker and easier.

The system has successfully completed 100,000 open and close cycles in private testing, demonstrating excellent long-term durability.
