Top-opening flap door soft-down stay from Sugatsune America is designed for upward and top-opening flaps using concealed or single knuckle hinges, so the same stay supports common hinge layouts on work surfaces, cabinets, or overhead compartments. The SDS-C301N/G design holds the door in both the closed and opened positions, providing stable access when the flap is lifted and consistent closure when it is shut. This stay is non-handed, so a single model works on either side of the cabinet, simplifying planning and inventory across multiple installs. A 90 degree opening angle positions the flap at a right angle to the cabinet, giving clear access to the interior while keeping the door in a predictable, repeatable position. The stay is designed to be used with a magnetic catch or touch latch, which supports clean front faces where handles are not desired.
The SDS-C301N/G top-opening flap door soft-down stay is designed around upward and top-opening flaps, so it aligns with lift-style doors that pivot from the top edge. Its non-handed design allows installation on either side, which gives flexibility when obstacles or interior components dictate where hardware can sit. The 90 degree opening angle defines the open stop, so case and flap dimensions can be laid out to clear ceilings, shelves, or adjacent cabinets while still providing access. The product is designed to work with a magnetic catch or touch latch, so the closure interface can be planned around those devices. The recommended 13/16 inch door thickness ties the stay performance to panel weight, supporting consistent soft-down behavior when flap height and weight are calculated against the torque rating.
This Sugatsune America SDS-C301N/G lid support and stay belongs in upward and top-opening flap applications that use concealed or single knuckle hinges, such as upper cabinets, overhead storage, or bench flaps. Because it is part of the lid supports and stays product class, it plays the role of controlling flap movement rather than acting as a primary hinge, so it pairs with the existing hinge hardware to manage holding positions. The 90 degree opening angle provides a defined stop that works well when the cabinet interior needs to be fully accessed without the flap traveling beyond vertical, which can be important in tight runs of cabinetry. Its non-handed nature helps installers standardize on one stay for either side, reducing part variation on projects with multiple upward-opening fronts.
The SDS-C301N/G soft-down stay is designed to hold the door in both closed and opened positions, so once the torque rating is matched to the lid height and lid weight using the lid height times lid weight times one half relationship, the stay can support predictable movement across a project. The recommended 13/16 inch door thickness directly influences lid weight, so following that guideline keeps the assembly within the intended operating range. Using this stay with a magnetic catch or touch latch allows the motion control of the stay to work together with the closure point provided by the catch or latch, giving a defined end position at closing. The non-handed configuration and 90 degree opening angle together help installers repeat the same layout from cabinet to cabinet, reducing layout changes and supporting consistent door behavior in multi-unit runs.
The SDS-C301N/G stay is designed for upward and top-opening flaps that use concealed or single knuckle hinges, so it works where the door lifts from the bottom edge and swings upward.
The 90 degree opening angle sets a fixed open position, allowing cabinet and flap dimensions to be planned so the lifted door clears nearby structures while providing full interior access.
The SDS-C301N/G is non-handed, so the same unit works on either side of a cabinet, simplifying layout changes and standardizing hardware across multiple openings.
The SDS-C301N/G stay has a recommended door thickness of 13/16 inch, which guides flap construction so weight and motion align with the torque rating relationship.
The SDS-C301N/G torque rating is based on lid height times lid weight times one half, so flap dimensions and mass are matched to the stay for consistent operation.
The SDS-C301N/G is designed to be used with a magnetic catch or touch latch, so the stay controls movement while the catch or latch defines the closed position.
The Sugatsune America SDS-C301N/G top-opening flap door soft-down stay ties upward or top-opening flaps to a defined 90 degree opening angle while holding doors in both closed and opened positions. Its non-handed design, recommended 13/16 inch door thickness, and torque rating based on lid height times lid weight times one half give fabricators clear parameters for building and sizing flaps. For projects using concealed or single knuckle hinges with magnetic catches or touch latches, this stay offers a structured way to coordinate hinge choice, flap construction, and motion control in a single, consistent setup.
