DSI-4400-15-15I door handle identifies this Sugatsune America sliding door handle as part of the DSI-4400 series, which helps match it with the correct sliding door hardware on repeat projects. This handle is classified as Sliding Door Hardware in the Sliding Door Pulls category, so it is intended as a functional pull for sliding door applications rather than a decorative cabinet knob. The handle is designed for use with DSI mounting kits, which ties it into a coordinated system for installing interior and exterior pulls on the same door. The exterior handle posts are threaded to accept screws, creating a direct mechanical connection to the door surface when paired with the appropriate mounting method. The interior handle posts use set screws for DSI mounting kits, so the interior pull locks onto the kit hardware instead of relying on through-bolting alone. A 150 mm center to center length with an overall length of 6-1/2 inches allows the handle to span a practical grip area on many door layouts.
This Sugatsune America DSI-4400-15-15I handle is described as an interior door handle, aligning it with the interior side of a sliding door assembly using DSI mounting kits. The posts for exterior handles in this system are threaded to accept screws, so the outside pull fastens via screw threads that engage the posts when installing onto the sliding door. The posts for interior handles have set screws for DSI mounting kits, so the interior handle attaches by tightening those set screws onto the kit components rather than threading directly into the door. This division between threaded exterior posts and set-screw interior posts gives the DSI system a defined installation method on each side of the door, supporting predictable assembly steps. Because the handle is for use with DSI mounting kits, it aligns with projects where installers are standardizing on Sugatsune DSI sliding door hardware across several openings.
This sliding door pull belongs to the Sugatsune America DSI-4400 series, which positions it within DSI sliding door hardware projects where coordinated components matter. The 150 mm center to center measurement provides a moderate span that suits many interior sliding door widths, from smaller passage panels to larger room dividers supported by DSI mounting kits. With an overall length of 6-1/2 inches, the pull extends slightly beyond the post spacing, giving occupants a substantial grasp point while keeping the hardware visually balanced on narrower stile widths. The 9/16 inch width defines a relatively slim bar section, which helps the handle sit comfortably on door faces without appearing oversized in residential or light commercial interiors. Being a Sliding Door Pull within Sliding Door Hardware, it plays the role of the main grip on the door, so the proportion of length, width, and post spacing is tuned to everyday sliding operation.
The DSI-4400-15-15I door handle uses 304 stainless steel material, giving installers a stainless metal construction that aligns with the expectations for durable-feeling sliding door hardware in woodworking environments. The satin finish on this 304 stainless surface creates a controlled reflection level that helps hide fingerprints more effectively than mirror-like finishes in regular door use. Posts for exterior handles are threaded to accept screws, so when used on the outside of a sliding door within the DSI system, the hardware engages by screw threads that create a solid attachment point for repeated pulling. Posts for interior handles have set screws for DSI mounting kits, so the interior pull locks to the kit components by tightening those set screws, which supports a clean interior appearance without visible through-bolts on the handle surface. The handle is specifically called out as for use with DSI mounting kits, which helps installers coordinate this part with the correct DSI kit numbers across multiple sliding openings on a job.
The DSI-4400-15-15I handle is classified as Sliding Door Hardware in the Sliding Door Pulls category, so it functions as the primary pull for sliding door applications.
The handle has a 150 mm center to center post spacing, an overall length of 6-1/2 inches, and a width of 9/16 inch, which defines its mounting span and grip profile.
The handle is made from 304 stainless steel with a satin finish, providing a stainless construction with a muted sheen suitable for coordinating with other satin door hardware.
On the exterior side, the handle uses posts that are threaded to accept screws, creating a mechanical screw-thread connection to the sliding door surface.
For interior use, the handle posts have set screws for DSI mounting kits, so the handle locks to the kit components by tightening those set screws.
The handle is described as a similar style to KPH series cabinet handles, which helps maintain a related visual style when both are used within the same project.
The Sugatsune America DSI-4400-15-15I stainless steel sliding door handle combines a 150 mm center to center span, 6-1/2 inch overall length, and 9/16 inch width with 304 stainless and a satin finish for everyday sliding door use. Its role as an interior door handle within the DSI mounting kit system, along with threaded exterior posts and set-screw interior posts, provides a defined interface for DSI sliding door assemblies. The similar style to KPH series cabinet handles helps align sliding pulls with existing handle choices on the same project. For projects built around DSI mounting kits and Sugatsune Sliding Door Hardware, this handle offers a matched option that fits the system layout.
