DSI-4400 internal door handle describes a 200 mm center to center interior pull designed as part of the Sugatsune America DSI sliding door hardware family, so it gives sliding doors a coordinated, purpose-built grip point for regular use. The handle measures 8-1/2 inches long and 9/16 inch wide, which provides a slim profile that works well where low projection and clean lines matter on sliding or cabinet doors. As a sliding door hardware component in the builders hardware category, it fits projects where a dedicated pull is needed instead of improvised hardware. The interior handle is identified by manufacturer part number DSI-4400-15-20I, which ties this piece directly to documented DSI system components on repeat jobs. Its similar style to KPH series cabinet handles supports visual continuity on projects that already use KPH pulls, so interior faces of doors can match nearby cabinetry.
The handle is specified "For use with DSI mounting kits (sold separately)", so the interior pull is engineered to integrate into the DSI sliding door hardware system rather than stand alone. Interior posts have set screws for DSI mounting kits, which means the handle locks to the kit hardware instead of relying on independent fasteners, supporting a stable, system-based installation. The 200 mm center to center dimension works directly with layout dimensions on DSI system drawings, helping door prep align with other DSI components on the same panel. As part of a sliding door hardware class, this handle fits into assemblies where matching DSI components control how loads and clearances are handled around the door.
This Sugatsune America DSI-4400-15-20I handle sits in the builders hardware and sliding door hardware categories, so it targets sliding door and sliding panel applications instead of standard swinging doors. The internal handle is described for use with DSI mounting kits, which places it on doors that already use DSI system tracks, guides, or related components. Its 8-1/2 inch length allows it to span a comfortable hand-grip area on door stiles for interior pulls. Because the style is similar to KPH series cabinet handles, the same project can use KPH on cabinets and this handle on sliding doors, keeping front-of-house millwork visually aligned.
The 200 mm center to center dimension on this sliding door handle establishes a fixed drilling pattern that can be repeated across multiple doors, which reduces layout variation from unit to unit. The 304 stainless steel material offers corrosion-resistant performance for indoor use, which supports long-term operation where frequent contact could otherwise mark or degrade lesser materials. A satin stainless finish keeps surface reflections controlled, which matters in well-lit interiors where gloss could highlight fingerprints or minor handling marks. Interior posts with set screws for DSI mounting kits create a mechanical lock between handle and mounting kit, supporting alignment with the DSI system and helping the handle stay correctly oriented as doors cycle. Similar styling to KPH series cabinet handles lets repeat projects apply the same visual rules, so drawings and hardware schedules can specify a consistent handle family across sliding and hinged fronts.
The DSI-4400 internal door handle has a 200 mm center to center drilling dimension, so hole spacing on the door can be laid out or matched to that exact distance.
The handle measures 8-1/2 inches long by 9/16 inch wide, giving a slim pull that suits modern sliding doors and narrow stiles.
The DSI-4400 internal door handle uses 304 stainless steel with a satin stainless steel finish, providing corrosion resistance and a low-glare appearance.
The interior handle posts have set screws for DSI mounting kits, so the pull secures directly to the mounting kit hardware within the sliding door assembly.
This product is described as an internal door handle, so it is intended for interior side pulling applications within the DSI sliding door hardware system.
The DSI-4400-15-20I is noted as similar in style to KPH series cabinet handles, which supports a coordinated look when both handle families appear on the same project.
The DSI-4400 internal door handle brings a 200 mm center to center layout, 8-1/2 inch by 9/16 inch sizing, and 304 stainless in a satin finish, so it fits sliding door hardware jobs that demand a slim, stainless pull. As a Sugatsune America component built for use with DSI mounting kits, it lines up with the DSI sliding door hardware system and mirrors the look of KPH series cabinet handles on coordinated millwork. For projects that call for a defined drilling pattern and matching stainless hardware across sliding and cabinet fronts, this DSI-4400 internal door handle provides a clearly specified option.
