NSDX-20LK lid stay, left-hand soft-down

Sugatsune Left Hand Soft-Down Lid Stay For Top-Opening Lids

Sugatsune Left Hand 20RK Adjustable Soft-Down Lid Stay gives left-side support for top-opening lids, so the door motion is controlled instead of dropping. This left-hand stay is designed for lid applications where the hinge is at the back and the lid swings upward. The nickel-plated finish provides a clean, metal surface that matches common hinge and lift system hardware, keeping projects visually consistent. As a down stay in the Lid Supports and Stays product class, it manages the downward motion of the lid for safer and more controlled closing. The unit is built for top-opening lids and holds the door in the closed position, which helps keep fronts aligned when the lid is at rest. It also supports the lid in specific open positions, so the opening angle is predictable every time.

Key Soft-Down Lid Functions For Daily Use

• The stay holds the door in the closed position, so the lid remains shut until opened, helping maintain alignment and reducing unintended movement in cabinets, benches, or work surfaces.
• It holds the door open at either 70 or 105 degree angles, depending on positioning, so installers can choose an opening angle appropriate to the application and user reach.
• A speed adjustment screw allows varying speeds of soft-close downward movement, letting the installer tune how quickly the lid settles down for a controlled, softer close.
• The stay is tested to 50,000 cycles, which demonstrates long-term motion performance where lids are opened and closed repeatedly in residential or commercial use.
• An adjustable 19 to 60 lbs. per square inch torque rating per piece, and 38 to 120 lbs. torque rating per pair, supports a range of lid sizes and weights when calculating lid torque requirements.

Installation Behavior And Angle Positioning Details

This NSDX-20LK stay is intended for the left side of top-opening lids, so it mounts on the left-hand side of the cabinet or box relative to the user. By positioning the stay so it holds at either 70 or 105 degrees, the installer sets how far the lid will open before stopping. The adjustable torque range per piece and per pair, from 19 to 60 lbs. per square inch and 38 to 120 lbs., lets the installer match the support to the lid height and lid weight. With the speed adjustment screw, the downward motion of the lid can be set so that the soft-close action matches the specific project, from lighter lids to heavier ones.

How This NSDX-20LK Stay Works In Projects

Left-Side Top-Opening Applications And Angles

The NSDX-20LK is specified as a left side, top-opening stay, so it is used on the left of lids that open upward from a horizontal surface. In this role, the stay supports the lid as it moves and holds the door at a controlled open angle. When installed so the hold position is 70 degrees, the lid stops at a moderate opening angle that suits tighter spaces or shallow cabinets. When positioned for a 105 degree hold, the lid opens further, which can improve access into deeper chests or work surface compartments. Because it functions as a down stay, it governs the motion as the lid returns toward closed, coordinating with hinges and other lift systems in the assembly. Serving within the Work Surface & Tables and Lift Systems, Lid Supports and Stays category, it fits into projects where controlled lid motion is part of the design.

Adjustable Torque And Soft-Down Speed For Consistency

The adjustable 19 to 60 lbs. per square inch torque rating per piece, and 38 to 120 lbs. per pair, means the NSDX-20LK can be tuned to match the torque created by the lid height and lid weight. This adjustment allows the stay to support the lid without overstraining the mechanism, which supports consistent operation over time. Since torque rating is defined as lid height multiplied by lid weight multiplied by one-half, the installer can relate the published ratings directly to the actual lid on the job. The speed adjustment screw provides a way to set the downward movement speed, so heavier lids can have a more gradual soft-close action and lighter lids can still close under control. The 50,000 cycle test rating indicates that the motion function is verified through repeated opening and closing, fitting installations where lids see frequent use across their service life.
