HDS-10S-SR/WT lid stay is a Sugatsune America super heavy duty support for a downward-opening flap door, so it controls drop-front motion in work surfaces, tables, or cabinets that need a stable, predictable opening action. This right-hand stay is designed for doors that open downward and use piano, butt, or drop hinges, so it integrates into common hinge layouts without changing your basic construction approach. The stay is made for use in pairs, so the flap load is shared and movement stays balanced across the door width. When the door is pushed toward the closed position, the HDS-10S mechanism is designed to self close and soft close, so the flap is pulled shut in a controlled way and impact at the frame is reduced. The white plastic and steel construction provides a neutral look with a robust internal structure for demanding flap applications.
The HDS-10S-SR/WT lid stay is defined by torque ranges that guide flap sizing, so the stay can be matched to door height and weight during layout. Torque for this stay is calculated as door height times one-half the door weight, giving a clear formula when planning new work or checking an existing flap. The K-Type range is 60 to 95 kgf.cm (52 to 82 lbs. inch) per pair, so lighter downward-opening flaps within that torque band can be supported. The M-Type range is 95 to 130 kgf.cm (82 to 112 lbs. inch) per pair, fitting heavier flaps within that window. The H-Type range is 110 to 160 kgf.cm (95 to 138 lbs. inch) per pair, and the S-Type range is 140 to 180 kgf.cm (121 to 156 lbs. inch) per pair, so there are options across progressively heavier or taller flap designs.
This Sugatsune America HDS-10S-SR/WT super heavy duty stay is built for downward-opening flap doors, so it suits drop-front cabinets, work surface extensions, or similar fronts where the door needs controlled downward travel. Because it is intended for use with piano, butt, or drop hinges, the stay works alongside continuous or individual hinge layouts, making it practical across different casework styles. Using the stay in pairs on a flap spreads the operating torque between left and right sides, which supports more even movement when the door is opened or pushed to close. The right-hand orientation of this model gives a defined mounting side, which is important when mirroring parts or matching an installation drawing. The white plastic and steel material pairing integrates into light-colored furniture or cabinet interiors while carrying super heavy duty flap loads defined by the torque ranges.
The HDS-10S-SR/WT lid stay uses specific torque ranges to align flap size and weight with controlled motion, so installers can select K-Type, M-Type, H-Type, or S-Type performance based on the calculated torque. With torque defined as door height times one-half door weight, the stay links real measurements directly to a suitable type, which supports repeatable results across multiple cabinets built from the same specification. K-Type at 60 to 95 kgf.cm (52 to 82 lbs. inch) per pair addresses lighter flaps, while M-Type at 95 to 130 kgf.cm (82 to 112 lbs. inch) per pair extends into medium loads. H-Type at 110 to 160 kgf.cm (95 to 138 lbs. inch) per pair and S-Type at 140 to 180 kgf.cm (121 to 156 lbs. inch) per pair cover heavier downward-opening fronts without changing the basic hardware concept. The stay self closes and soft closes when the flap is pushed toward shut, so once the torque is matched, the motion remains consistent from unit to unit, helping reduce rework when producing a series of cabinets or workstations.
The HDS-10S-SR/WT lid stay is designed for a downward-opening flap door, so it supports drop-front or similar doors that swing down and need controlled movement.
This Sugatsune downward-opening stay is specified for use with piano, butt, or drop hinges, so it integrates with these standard hinge types in flap door projects.
This soft-closing lid stay is used in pairs, so one stay is mounted on each side of the flap to share the load and support balanced opening and closing.
Torque for this lid stay is calculated as door height times one-half door weight, which ties flap dimensions directly to the K, M, H, or S torque ranges.
This HDS-10S stay supports K-Type 60-95, M-Type 95-130, H-Type 110-160, and S-Type 140-180 kgf.cm per pair, covering a progression from lighter to heavier flap doors.
This super heavy duty stay uses white plastic and steel, combining a light-colored exterior with a metal structure suited to the specified torque ranges.
The Sugatsune America HDS-10S-SR/WT lid stay provides self-closing, soft-closing control for downward-opening flap doors using piano, butt, or drop hinges, so it fits neatly into many cabinet and work surface layouts. With defined torque ranges from K-Type through S-Type and a clear torque formula based on door height and weight, this super heavy duty right-hand stay can be matched to a wide spread of flap sizes. For projects needing predictable downward motion and controlled closing on a white plastic and steel stay used in pairs, this HDS-10S-SR/WT configuration is a focused choice for new builds or upgrades.
