DSI-4400 internal door handle gives sliding doors a straight, stainless pull that matches Sugatsune America hardware lines. The handle measures 10-5/8 inches long and 13/16 inch wide, so it spans a comfortable grip area on interior sliding door panels. A 250 mm center to center post spacing provides a predictable drilling layout that aligns cleanly with typical sliding door stiles. Material is 304 stainless steel, which resists corrosion in normal interior environments and keeps the pull looking consistent beside other stainless components. The satin stainless finish softens reflections on the handle face, which helps the pull read cleanly against door surfaces in residential or commercial interiors. The handle design belongs to the builders hardware sliding door pulls class, so it works as the primary handhold on sliding panels rather than as cabinet hardware.
This Sugatsune America DSI-4400 internal door handle is built for use with DSI mounting kits, so the interior posts are configured to accept those kits directly. The 250 mm center to center dimension defines the distance between mounting posts, giving a simple reference when laying out mounting kit locations on sliding door panels. Posts for interior handles use set screws with DSI mounting kits, so the handle clamps to the kit rather than relying on through-bolting. That approach lets the installer work from the interior side of the panel when tightening the pull. The sliding door hardware classification signals that this handle is intended as part of a larger DSI sliding system, using the same kit interface that other DSI components use.
The DSI-4400 internal door handle belongs in sliding door assemblies where DSI mounting kits are already specified. Its 250 mm center to center spacing keeps post locations consistent across doors, which is useful on wide openings with multiple sliding panels. The handle follows a similar style to KPH series cabinet handles, so designers can carry a visual line from casework pulls to door pulls in the same space. Classified under sliding door hardware and sliding door pulls, this part plays the main gripping role on interior sliding door leaves rather than on small cabinet fronts. The 10-5/8 inch length creates a vertical or horizontal pull zone that reads clearly at hand height on full-size doors.
Material choice of 304 stainless steel gives the DSI-4400 handle a solid feel during door operation, which helps users control heavier sliding panels comfortably. The satin stainless finish keeps fingerprints less visually prominent than a mirror surface, which matters on frequently handled interior doors. Posts for interior handles are designed with set screws for DSI mounting kits, giving a repeatable way to secure the pull without improvising fastener interfaces. Using DSI mounting kits with this handle standardizes the installation approach across multiple doors, reducing layout variation. By keeping the center to center at 250 mm and the width at 13/16 inch, Sugatsune America provides known dimensions that support jig-based drilling and consistent sightlines along aligned sliding door runs.
