Sugatsune NSDX-20LK Door Damper 60 Lb Top Opening Flap

Product Description

The SUGATSUNE NSDX-20LK is a door damper engineered to control the motion of top opening flap doors and similar hinged panels. It provides a 60 lb load capacity, making it suitable for cabinet lids, access hatches, and lightweight overhead flap assemblies found in residential and light commercial millwork. The damper measures 8.5 inches in overall length and 0.875 inches in width, with a nickel finish over a steel and zinc alloy body. Cabinetmakers, millwork installers, and finish carpenters install this component to prevent doors from slamming open or dropping uncontrolled.

The NSDX-20LK is designed for top opening flap applications where controlled motion and a clean finish appearance are required. Typical installations include kitchen lift-up cabinet doors, display case lids, and access panels where a damped travel stroke reduces impact and noise. The nickel finish suits interior environments where corrosion resistance and aesthetic consistency with hardware trim are both considerations.

Installation Notes

Installation is typically performed by cabinetmakers, millwork installers, or finish carpenters using standard hand tools. Secure all fasteners fully before cycling the door under load to verify damper travel. Do not exceed the 60 lb rated load capacity, as overloading may damage the damper mechanism. Confirm door alignment and hinge torque are correct before finalizing the damper mount.
