DSI-4400 internal door handle defines a dedicated pull for sliding door projects, so installers get a known part with repeatable results on interior runs. This handle is classified as sliding door hardware, which aligns it with typical door pull applications where a flush-free grip is needed for smooth sliding movement. The product sits in the sliding door pulls category, so it is geared toward doors that need a fixed handhold instead of a rotating lever. Sugatsune America branding ties it into a recognized builders hardware line, which helps maintain consistency across projects that already use related components. A 350 mm center to center dimension sets the post spacing, giving fabricators a clear drilling layout across multiple doors. That same fixed spacing supports clean visual alignment when several panels share the same hardware pattern.
The 350 mm center to center measurement on this internal stainless steel handle defines the distance between post mounting points, so drill patterns can be laid out precisely across several doors. Because posts for exterior handles are threaded to accept screws, fabricators can rely on that thread engagement for a solid attachment into compatible structures. Interior handle posts use set screws for DSI mounting kits, which means the handle locks to the mounting kit rather than depending directly on the door substrate. For installers, this split design between exterior threaded posts and interior set screw posts allows a coordinated approach on both sides of a sliding door while still using the same handle family.
This internal stainless steel 350 mm center to center handle fits sliding door applications in the builders hardware space where a pull-style grip is needed. Being part of the sliding door hardware product class keeps it aligned with door panels rather than drawers or hinges, which steers it toward openings that travel on a track. Because the style is similar to KPH series cabinet handles, it can sit on larger door faces while nearby cabinets use KPH handles, creating a unified look across doors and casework. The satin stainless finish works well on projects that call for a modern metal appearance without high reflectivity, helping the pull match other satin stainless components in the same room.
The handle is specified for use with DSI mounting kits, tying it into a defined mounting system that streamlines hardware selection when a project already uses DSI components. Posts for exterior handles are threaded to accept screws, which gives installers a direct mechanical fastening option into suitable structures and supports a firm feel when the door is operated. Posts for interior handles use set screws for DSI mounting kits, so the handle clamps onto the kit for a repeatable installation approach on the room side of the door. The 304 stainless steel material provides a corrosion-resistant base metal in normal interior woodworking settings, helping the handle keep its structural integrity and feel solid under frequent use. Combined with the satin stainless steel finish, the material supports an appearance that remains consistent alongside other satin 304 stainless items on the same installation.
The handle is categorized as sliding door hardware in the sliding door pulls group, so it is intended for use on sliding door panels that need a pull-style grip.
