DSI-4400 internal door handle identifies this Sugatsune America handle as part of the DSI sliding door hardware family, which matters when matching components across multiple openings on the same job. The handle is described as an internal stainless steel model, so it is intended for interior mounting where a clean, consistent look across rooms is important. The center to center dimension is 300 mm, which gives you a defined post spacing to lay out on the door and helps keep multiple doors aligned visually. Overall length is specified as 12-3/8 inches and width as 9/16 inch, so you know the pull will sit slender on the stile and leave room around adjacent hardware. The product sits in the sliding door pulls category under sliding door hardware, so it is suited to sliding door applications rather than swinging cabinet doors.
The product description states that it is for use with DSI mounting kits, so the handle is designed to work within that system and gives you a predictable interface on DSI sliding door jobs. Posts for exterior handles in this DSI family are threaded to accept screws, which means the outer side of the assembly can be secured by fasteners from the opposite face. Posts for interior handles, such as this internal model, have set screws for DSI mounting kits, so the interior side locks onto the mounting hardware without visible through-screws. The 300 mm center to center spacing provides a fixed drilling layout, helping installers set consistent reference points on multiple doors and reduce layout time.
The handle is identified as a sliding door pull in the sliding door hardware class, so it is intended to act as the user grip on sliding door panels rather than on hinged doors. The overall length of 12-3/8 inches provides a substantial gripping area along the stile, which helps occupants get reliable leverage on taller sliding panels. With a width of 9/16 inch, the handle presents a slim profile on the face of the door, which matters when doors stack or pass close to adjacent walls and trim. Being described as internal stainless steel positions this model for the interior side of a door where a stainless aesthetic is desired without exposing an exterior-focused post configuration. The similar style to KPH series cabinet handles allows designers to carry a coordinated look across cabinet fronts and sliding doors, which can simplify hardware selection on large millwork packages. Listing under builders hardware and sliding door pulls also places the handle within a familiar category for hardware schedules on architectural drawings.
The callout "For use with DSI mounting kits" ties this handle directly to a defined mounting system, which helps installers plan hardware stacks knowing the posts and set screws are made to engage that kit. Interior handle posts using set screws for DSI mounting kits provide a way to secure the pull from the interior side, which reduces exposed fastener heads on the pull surface and gives a cleaner finish. Exterior handle posts in the same family are threaded to accept screws, so both sides of a through-door assembly can be fastened using interfaces tailored to their location. The 300 mm center to center dimension gives a fixed distance between posts, which supports jig-based drilling and consistent alignment across multiple doors in a run. The 304 stainless steel material offers resistance to staining and corrosion in typical interior service, supporting long-term appearance in commercial or residential sliding applications. The satin stainless finish softens fingerprints and glare compared with polished finishes, which is helpful in high-touch areas like passage doors.
