DSI-4400 external door handle gives sliding doors a dedicated pull point using a handle designed for the DSI sliding door hardware system. The handle measures 250 mm center to center, so pull posts line up consistently on DSI layouts, which supports predictable mounting locations across multiple doors.
The overall handle length is 10-5/8 inches and the width is 13/16 inch, creating a pull that spans a useful section of the door face without overpowering the panel. This proportioned size supports a comfortable grip while keeping the hardware footprint controlled for cleaner looking sliding installations.
The handle is part of Sugatsune America sliding door hardware and sits in the Sliding Door Pulls category, so it is intended as a working pull on sliding door projects rather than a decorative cabinet knob. That role helps installers assign it to the right opening when planning hardware.
The material is 304 stainless steel with a satin stainless steel finish, so the pulling surface is metal from base material through finish. This construction supports a hard-wearing contact point that resists damage from frequent hand contact better than soft, coated materials.
The 250 mm center to center dimension sets the spacing between the posts on this DSI-4400 external door handle, which directly affects drilling and layout. Using a fixed center-to-center value simplifies door prep on multiple panels, because the same drilling pattern can be repeated without re-measurement.
Posts for exterior handles are threaded to accept screws, so the outside handle connects to the DSI mounting elements with a screw-driven joint. That threaded interface allows the pull to draw tight against the door skin when fastened, which supports a solid-feeling grip under sliding loads.
On the interior side, posts use set screws for DSI mounting kits, so the inner handle secures by tightening against the DSI mounting hardware rather than relying on a visible screw head through the pull. This method keeps the interior appearance cleaner while still tying the handle rigidly into the mounting kit.
Similar style to KPH series cabinet handles helps designers visually coordinate this sliding door pull with other Sugatsune pulls on cabinet doors in the same room. Matching style across swinging and sliding fronts supports a more unified hardware layout on built-ins and casework.
This Sugatsune America DSI-4400 external door handle belongs to the Sliding Door Pulls category, so it is intended for sliding door hardware projects rather than traditional hinged doors. The handle is specified as external, which focuses its role on the main pulling face where the user frequently grabs to move the door.
Because it is designed for use with DSI mounting kits, it lines up with installations that already rely on DSI sliding door hardware. Keeping the handle within the DSI system helps align pull placement with other DSI components on the panel, supporting consistent spacing from door edges and hardware tracks.
The 10-5/8 inch length bridges a reasonable span on wider sliding panels, giving the user leverage at multiple hand positions along the pull. At the same time, the 13/16 inch width keeps the profile narrow, which helps the handle sit comfortably on contemporary door designs with lean hardware proportions.
The similar style to KPH series cabinet handles ties this sliding door pull into a broader Sugatsune aesthetic. On projects where KPH series cabinet handles are already on doors or drawers, this similarity allows sliding doors to carry a related pull geometry, which maintains a more deliberate visual rhythm across the run of casework.
The 250 mm center to center dimension on the DSI-4400 external door handle acts as a built-in layout reference when drilling for DSI mounting kits. With that fixed spacing, shop or site crews can template hole locations once and repeat them accurately, which helps reduce layout variation from door to door.
Using 304 stainless steel as the base material creates a handle body that holds its shape under pulling forces common to sliding doors. Over repeated use, this material choice supports a stable gripping edge, which is especially relevant on wider or heavier sliding panels where users apply more force.
The satin stainless steel finish modifies the surface appearance of the 304 stainless, softening reflections while still showing the metal character. In practice, this finish pairs well with other satin stainless elements around the opening, helping the handle blend with hinges, sliding tracks, and nearby cabinet hardware from similar finish families.
Posts for exterior handles being threaded to accept screws keeps the fastener interface inside the post, so the load from pulling is transferred straight into the door and DSI mounting kit components. That direct load path supports a firm handling feel, which can help limit flex when occupants repeatedly slide the door from the same grip point.
Posts for interior handles using set screws for DSI mounting kits give installers a way to secure the interior pull without exposing screw heads at the hand surface. This detail supports a smoother gripping surface on the room side of the door while still tying both sides of the pull assembly back to the same DSI mounting hardware.
The DSI-4400 external door handle is categorized under Sliding Door Pulls and Sliding Door Hardware, so it is designed to serve as a working pull on sliding door applications.
The handle has a 250 mm center to center post spacing, with an overall length of 10-5/8 inches and a width of 13/16 inch, giving a balanced gripping area on sliding doors.
The handle is for use with DSI mounting kits. Exterior handle posts are threaded to accept screws, while interior posts use set screws that fasten to the DSI mounting kits.
The DSI-4400 external door handle is made from 304 stainless steel with a satin stainless steel finish, providing a corrosion-resistant metal grip with a muted, brushed-style appearance.
This handle has a similar style to KPH series cabinet handles, so it visually coordinates with KPH pulls when both are used on the same project.
The manufacturer part number is DSI-4400-20-25E, which identifies this specific Sugatsune America external sliding door handle within the DSI-4400 series.
The DSI-4400 external door handle from Sugatsune America ties directly into DSI mounting kits and Sliding Door Hardware, aligning with installations that already rely on that system. Its 250 mm center to center spacing, 10-5/8 inch length, and 13/16 inch width define a repeatable drilling pattern and a practical gripping footprint for sliding doors.
With 304 stainless steel construction and a satin stainless steel finish, the handle supports long-term use where hands repeatedly pull the same edge. When a sliding door pull is needed that fits the DSI layout and coordinates with KPH series cabinet handles, this model gives a clearly defined size and material set ready for specification.
