DSI-4400 external door handle is a Sugatsune America handle designed for use with DSI mounting kits, so it drops directly into DSI sliding door hardware layouts where that system is used. The handle is categorized as sliding door hardware and sliding door pulls, which positions it for applications where a dedicated pull is needed on moving door panels. The handle measures 300 mm center to center and 12-3/8 inches long by 9/16 inch wide, giving installers a clearly defined drilling layout and grip profile that aligns with typical sliding door stiles. The design offers separate posts for exterior and interior handles, so each side of the door can be built with hardware suited to its specific mounting method within the DSI system.
The DSI-4400-15-30E handle provides a 300 mm center-to-center post spacing, giving a fixed drilling pattern that can be laid out consistently across multiple doors in a run. Exterior posts are threaded to accept screws, so the installer can fasten the outside handle directly through prepared holes to the door or associated DSI components. Interior posts use set screws with DSI mounting kits, allowing the inside pull to be tightened onto the mounting hardware after the exterior fasteners are positioned. The 9/16 inch width and 12-3/8 inch length give enough bar length to bridge across stile material while keeping the handle aligned with typical sliding door proportions. With this combination of defined spacing and distinct interior and exterior post designs, the handle supports repeatable installation in DSI-based sliding door projects.
This DSI-4400 external door handle is part of Sugatsune Americas sliding door hardware line, so it is suited to sliding door applications that use the DSI system. Its 300 mm center-to-center spacing and 12-3/8 inch overall length fit doors where a longer pull is preferred along the stile, such as full-height sliding panels or wider cabinet sliders. The handle belongs to the builders hardware and sliding door pulls categories, which places it naturally into woodworking and architectural projects managed by trade professionals. With a style similar to KPH series cabinet handles, it can be specified in spaces where KPH pulls are already used on adjacent doors or drawers, helping projects maintain a consistent pull profile across sliding and hinged fronts.
The DSI-4400-15-30E handle is made from 304 stainless steel, so the grip and posts are built from a material widely used in builders hardware for strength and surface integrity in normal woodworking environments. Its satin stainless steel finish provides a subdued sheen that coordinates with other satin stainless hardware, reducing visual mismatch across hinges, pulls, and sliding components in the same project. Exterior posts are threaded to accept screws, creating a solid mechanical connection that ties the outer pull directly into the door or DSI structure for stable operation. Interior posts use set screws with DSI mounting kits, letting the inside handle lock down onto the mounting system once alignment is established. The handle style is noted as similar to KPH series cabinet handles, supporting projects that want sliding door pulls to echo KPH handle lines for a unified design.
The DSI-4400-15-30E handle is classified as sliding door hardware and a sliding door pull, so it is designed for sliding door applications using the DSI system.
The 300 mm center-to-center spacing gives a fixed drilling layout, allowing installers to repeat the same hole pattern across multiple doors for consistent handle alignment.
On the DSI-4400-15-30E, exterior posts are threaded to accept screws, creating a direct screw-fastened connection between the outer handle and the door assembly.
The interior posts on this handle use set screws for DSI mounting kits, so the interior pull tightens onto the DSI hardware after the exterior side is fastened.
The Sugatsune America DSI-4400 handle provides 300 mm center to center spacing with an overall length of 12-3/8 inches and a width of 9/16 inch for the pull bar.
This door handle is described as similar in style to KPH series cabinet handles, allowing visual coordination where KPH pulls are used on nearby cabinetry.
The DSI-4400 external door handle from Sugatsune America ties directly into DSI mounting kits, so it fits sliding door projects already based on that hardware system. With 300 mm center-to-center spacing, 12-3/8 inch length, and 9/16 inch width, it offers a defined pattern that aligns well with typical sliding door stiles. Separate threaded exterior posts and interior posts with set screws give distinct mounting approaches for each side of the door while still working within the DSI framework. When specifying sliding door hardware through Wurth Baer Supply, this handle suits projects needing a satin 304 stainless steel pull that coordinates with KPH-style cabinet handles and supports consistent installation across multiple panels.
