DSI-4400 internal door handle defines this Sugatsune America pull as part of the DSI sliding door system, so it serves as the interior gripping point on compatible doors. The 300 mm center to center dimension establishes a long, comfortable hand span, which helps users operate larger or heavier sliding door leaves with better control. The overall length of 12 inches with a 1-3/16 inch width creates a substantial handle profile that feels secure under hand while still suiting slim sliding door stiles. Being classified under sliding door hardware and sliding door pulls connects this product directly to interior sliding, bypass, or similar door applications where a fixed, stable pull is needed. The internal handle role complements exterior handles in the same system, supporting a consistent layout on both sides of the door for predictable operation.
The description states this handle is for use with DSI mounting kits, which ties its mounting geometry directly to that system so the interior handle interfaces correctly with the DSI hardware layout. Posts for interior handles are specified as having set screws for DSI mounting kits, which means the handle locks onto the mounting components by tightening those set screws, creating a secure mechanical engagement on the interior side of the door. The 300 mm center to center dimension defines the exact spacing between posts, guiding the installer where to position mounting points relative to the door edge for repeatable fit across multiple openings. By matching the DSI naming in the SAP description and manufacturer part number DSI-4400-30-30I, this pull aligns with the broader DSI-4400 series geometry, supporting consistent fit when used alongside other DSI-4400 components in a project.
The product is described as internal stainless door handle hardware within the sliding door pulls category, so it is suited for the room side of sliding or bypass doors where a fixed pull is required instead of a latch. The 12 inch length provides a generous gripping area along the stile, which works well on taller doors where users may grab the handle at different heights during operation. With a 1-3/16 inch width, the handle presents a narrow front profile, so it occupies modest face space on the door while still providing enough surface for a firm grasp. The 304 stainless steel material positions this handle for interior locations that experience regular human contact, since stainless steel maintains its integrity under repeated handling. Because the style is noted as similar to KPH series cabinet handles, this pull can visually align sliding doors with nearby cabinet fronts that already use KPH-style pulls, allowing a continuous hardware language through kitchens, closets, or built-ins.
The explicit 300 mm center to center spacing sets the core drilling pattern, which supports accurate replication of hole positions from door to door, reducing layout variability across a multi-opening project. Interior handle posts are specified as having set screws for DSI mounting kits, so once the mounting kit elements are positioned, the installer secures the pull by tightening those set screws, creating a positive lock that resists loosening under pulling forces. The satin stainless finish on 304 stainless steel offers a uniform surface, so when multiple handles are installed in a line of doors, the visual appearance remains consistent from one opening to the next. The identification as DSI-4400 INT door handle in the SAP description links the part directly to the DSI-4400 series, guiding specifiers who are matching interior pulls with exterior handles that share the same series alignment. By being classified under sliding door hardware, this handle stays dedicated to the sliding function, simplifying hardware schedules where swing door and sliding door pulls must remain clearly differentiated for field crews.
The handle is categorized as sliding door hardware and a sliding door pull, so it is intended for sliding or similar interior door applications that need a fixed pull.
The handle has posts spaced 300 mm apart, so installers drill mounting points at that fixed distance, which standardizes layout and simplifies repetitive door preparation.
Posts for interior handles have set screws for DSI mounting kits, so the handle is secured by tightening those set screws onto the compatible DSI kit components.
The handle is made from 304 stainless steel with a satin stainless steel finish, which provides a durable base material and a low-glare, visually consistent surface.
The handle measures 12 inches long and 1-3/16 inches wide, giving a long gripping area while keeping a relatively slim profile on the door face.
The product is described as similar in style to KPH series cabinet handles, allowing coordinated appearance between sliding doors and nearby KPH-equipped cabinets.
The DSI-4400 internal door handle from Sugatsune America combines 304 stainless steel construction, a satin stainless finish, and a 300 mm center to center layout, so it suits interior sliding doors that need a coordinated, system-based pull. The set-screw interior posts for DSI mounting kits tie this handle directly into the DSI sliding door platform, which helps installers match interior pulls to the correct hardware family. For projects that already use KPH series cabinet handles, the similar styling allows this sliding door pull to extend that look to larger openings, keeping hardware consistent across the space. Use the DSI-4400-30-30I designation when adding this handle to hardware schedules or ordering through Wurth Baer Supply to align it with the rest of the DSI sliding door hardware set.
