HDS-10S-HR/WT lid stay is a heavy duty downward-opening stay from Sugatsune America that supports flap doors using piano, butt, or drop hinges such as SDH-001 and SDH-P, so flap fronts can open downward in a controlled arc. This stay is designed for downward-opening flap doors, so it handles the swing and weight that work surfaces, cabinet fronts, or access panels place on the hinges when opened. The product is a right-hand version, so it suits layouts that call for a handed stay on the right side of the opening. The soft-closing function engages when the flap is pushed toward closed, so the HDS-10S brings the door to a gentle stop instead of a hard slam on the cabinet. This lid stay is described as heavy duty in the product data, so it is intended for flap doors that generate higher torque values than light decorative fronts.
The Web Description specifies that the HDS-10S series is used in pairs, so torque capacity is referenced per pair rather than per single stay, which matters when matching flap size and weight to the hardware layout. The torque calculation is given as torque equals door height times one-half times door weight, so installers can translate real door dimensions and weight into a torque figure that aligns with the available types. The listed K-Type range of 60 to 95 kgf.cm per pair (52 to 82 lbs. inch per pair) and M-Type range of 95 to 130 kgf.cm per pair (82 to 112 lbs. inch per pair) show how different versions address different flap loads, which guides selection within the HDS-10S series. The product data also describes H-Type and S-Type ranges that climb up to 180 kgf.cm per pair (156 lbs. inch per pair), so heavier or taller flaps can still stay within the stated torque window.
The category listing places this product in work surface and tables, lift systems, lid supports and stays, and down stays, so it is oriented toward applications where a front or lid pivots to provide access or workspace. The Web Description states that it is for a downward-opening flap door, so it suits fronts that swing down rather than lift up, such as counter extensions or lower access panels. Its compatibility with piano, butt, or drop hinges such as SDH-001 and SDH-P means it works in projects where those hinge formats are already part of the design, which keeps the hardware set consistent across a run of cabinets. Being a heavy duty right-hand stay, it can be assigned to the right side of wider flaps while another stay handles the opposite side, which spreads load across both stays and hinges.
The Web Description notes that when pushed to close, the HDS-10S is designed to self close and soft close, so once the flap is nudged past a certain point the mechanism carries it through a controlled, damped motion to the fully closed position. This behavior limits the speed of the closing flap, which reduces impact on the cabinet face and hinge knuckles over repeated cycles. The specified torque calculation of door height times one-half times door weight gives a straightforward method to quantify flap load, which reduces guesswork when aligning a real door to one of the K-Type, M-Type, H-Type, or S-Type torque bands. By matching the computed torque to a band range such as 110 to 160 kgf.cm per pair or 140 to 180 kgf.cm per pair, the stay can operate within its described working window, which supports consistent motion and longevity in service.
The HDS-10S-HR/WT lid stay is designed for downward-opening flap doors, so it supports fronts that pivot downward to open rather than lifting upward.
The HDS-10S-HR/WT stay is designed to self close and soft close when the flap is pushed toward shut, so it slows the motion and reduces closing impact.
The HDS-10S-HR/WT uses torque equals door height times one-half times door weight, so selecting the correct torque band keeps flap motion within the intended operating range.
The HDS-10S series offers K-Type, M-Type, H-Type, and S-Type with ranges from 60 to 180 kgf.cm per pair, so different door sizes and weights can be addressed.
The HDS-10S-HR/WT stay is described for use with piano, butt, or drop hinges such as SDH-001 and SDH-P, so it works alongside those hinge types on a flap door.
The HDS-10S-HR/WT is a right-hand heavy duty stay, so it is intended to mount on the right side of a downward-opening flap in the hardware layout.
The HDS-10S-HR/WT lid stay combines soft-closing action, a defined torque calculation method, and heavy duty torque bands from 60 to 180 kgf.cm per pair, so flap doors can be matched to a stay that supports their size and weight. Its design for downward-opening flap doors using piano, butt, or drop hinges such as SDH-001 and SDH-P means it integrates into standard hinge choices on work surfaces and access fronts. Selecting this right-hand Sugatsune America stay through Wurth Baer Supply aligns hardware choice with a trade-focused lid supports and stays range that centers on controlled flap motion.
