DSI-4400 internal door handle describes a Sugatsune America sliding door pull designed for internal use on sliding doors where a dedicated handle improves control. The handle uses 250 mm center to center mounting, so the posts land on a predictable spread for layout and drilling. Overall, the pull measures 11 inches long by 1-3/16 inches wide, giving a substantial grip area without overpowering the door face. The handle is part of the DSI-4400 series in Sugatsune sliding door hardware, which helps match existing layouts that already use this system. Being classified as sliding door hardware keeps it focused on door movement, rather than cabinet-only use. Designed as a door handle rather than a small cabinet pull, it suits taller sliding panels where a longer pull improves reach and operation.
This sliding door handle is designed for use with DSI mounting kits, so it ties directly into the DSI hardware system rather than a generic bracket layout. Posts for exterior handles are threaded to accept screws, which lets threads carry the load for doors where through-bolting from the outside is preferred. Interior handle posts use set screws for DSI mounting kits, so the interior side can clamp securely to the kit hardware without exposed bolts on the user side. This division between threaded exterior posts and set-screw interior posts allows the handle to be used in a back-to-back configuration within the DSI system. Working within a defined mounting kit system helps reduce layout guesswork and supports repeatable results across multiple doors in the same installation.
This product sits in the builders hardware category under sliding door pulls, placing it directly in the interior sliding door space rather than general cabinet knobs. The 11 inch length gives enough vertical reach on taller door panels, so users can grab the handle comfortably from different heights. With 1-3/16 inches of width, the grip area feels more substantial than a narrow bar, which helps when moving heavier or larger sliding doors. The center to center dimension of 250 mm works well across multiple doors on the same project, since the same drilling pattern can be reused from panel to panel. Because the handle shares a similar style to KPH series cabinet handles, it supports a coordinated look between sliding doors and nearby cabinets that already use KPH pulls. That visual alignment keeps mixed hardware runs from feeling random when moving from doors to casework.
The connection to DSI mounting kits means the handle is intended to integrate directly with DSI sliding door systems, rather than relying on improvised hardware. Posts for exterior handles are threaded to accept screws, so they engage positively with threaded fasteners and give a solid mechanical joint through the door skin. On the interior side, posts with set screws for DSI mounting kits grip the mounting hardware firmly, helping the handle resist loosening during repeated use. Using 304 stainless steel for the handle body keeps the structure stable under repeated pulls, while the satin finish manages everyday marks in normal interior conditions. The 250 mm center to center spacing standardizes layout, which streamlines drilling jigs and reduces alignment variation between doors. With the style echoing KPH series cabinet handles, designers can specify this pull where they want sliding doors and cabinet fronts to share a family look.
The handle is classified as sliding door hardware in the builders hardware category, so it is intended for use on interior sliding door applications.
