Soft closing lid stay describes this Sugatsune America light duty right-hand stay designed for a downward-opening flap door. It supports controlled movement of the flap so the front drops in a managed way, which matters when you want consistent, predictable operation on work surfaces and cabinet fronts. This lid supports and down stays product is built for use with a downward-opening flap door, so it fits projects where the door swings down instead of lifting up. The white plastic and steel construction provides a finished look that blends with light interiors while delivering the strength of metal components for repeated use on light duty applications.
This stay is identified as HDS-10S-KR/WT, which pins it to Sugatsune's HDS-10S series and makes matching or reordering straightforward when you are standardizing a hardware set. The design is used in pairs, so each installation is planned around two stays working together to share the load and match the stated torque ranges.
This HDS-10S-KR/WT stay is specified for downward-opening flap doors used with piano, butt, or drop hinges, so the mounting layout assumes the hinge carries the primary pivot while the stay controls the motion. The stay is used in pairs, so torque planning is based on two units sharing the load on one flap. Sugatsune provides a torque calculation of torque = door height x 1/2 x door weight, which turns basic door dimensions into a usable selection value when matching the stay type to the application. The white plastic and steel construction supports reliable mounting to typical cabinet materials, and the light duty rating guides you toward flap doors where the door height and weight stay inside the given torque ranges.
This Sugatsune lid supports and stays component is aimed at downward-opening flap doors, so it fits cabinets, work surfaces, or tables where the front panel drops to provide access. The stay is meant to work with piano, butt, or drop hinges such as SDH-001 and SDH-P, so it fits layouts where those hinges set the pivot line and the stay manages motion. The HDS-10S design is used in pairs, so each flap door is supported by two right-hand light duty stays, which helps maintain even action across the width of the door. The white plastic and steel build works well where a light-colored interior or face is preferred, helping the hardware visually recede while steel components handle repeated opening and closing cycles on a light duty flap.
The product lives in the work surface and tables, lift systems, and down stays category, so it suits projects where a horizontal surface or front drops down and needs guided support. The downward-opening function also fits drop fronts on desks or cabinetry where a controlled fall is more important than a lift-up motion, allowing the installer to match the hardware function to the intended user motion.
The HDS-10S stay is defined by a specific torque calculation: torque equals door height times one-half times door weight, so door size and mass directly set the torque demand. This value then matches to Sugatsune's torque groups, which for this product line are K-Type 60 to 95 kgf.cm (52 to 82 lbs. inch) per pair, M-Type 95 to 130 kgf.cm (82 to 112 lbs. inch) per pair, H-Type 110 to 160 kgf.cm (95 to 138 lbs. inch) per pair, and S-Type 140 to 180 kgf.cm (121 to 156 lbs. inch) per pair. These ranges give a defined window for pairing door characteristics with the stay type, so an installer can select a group that keeps the flap operating within the intended soft close performance. Because the stay is designed to self close and soft close when pushed, operating within the specified torque range supports consistent closing speed and feel across multiple doors in the same run.
Using the defined torque equation also standardizes planning when a shop repeats a cabinet line, since door height and weight convert into a predictable hardware selection. The light duty rating further narrows use to flap doors where the torque result aligns with the stated K, M, H, or S type bands, reinforcing consistent performance instead of trial-and-error matching.
The HDS-10S-KR/WT soft closing lid stay is designed for a downward-opening flap door, so it supports fronts that swing down to open rather than lifting upward.
The HDS-10S is made to self close and soft close when pushed, so after you start closing the flap, the stay controls final travel to reduce slamming.
The HDS-10S design is used in pairs, so each downward-opening flap door uses two stays that share the load and match the stated torque ranges.
This lid stay is specified for use with piano, butt, or drop hinges such as SDH-001 and SDH-P, so those hinges supply the pivot while the stay manages movement.
The torque calculation uses torque equals door height times one-half times door weight, turning door dimensions into a selection value that aligns with the HDS-10S torque groups.
The HDS-10S torque groups cover K-Type 60-95, M-Type 95-130, H-Type 110-160, and S-Type 140-180 kgf.cm per pair, which align with different door height and weight combinations.
The Sugatsune America HDS-10S-KR/WT soft closing lid stay combines a light duty right-hand design with defined torque ranges for downward-opening flap doors, so it serves projects needing consistent, soft-closing motion. The white plastic and steel construction delivers a clean look alongside metal strength for repeated everyday use. With its self closing and soft closing behavior, the stay supports quieter operation on work surfaces, tables, and cabinets built around a drop-front design. For installers or shops standardizing hardware, the clear torque calculation and group ranges provide a repeatable way to match flap dimensions to this lid supports and down stays solution.
