DSI-3330 internal door handle defines this Sugatsune America pull as a dedicated internal handle for sliding door applications, so it serves projects that use the DSI sliding door hardware system. The handle is described as an internal rounded stainless steel 500 mm center to center design, which gives a long gripping span that works well on taller or wider sliding doors where users need a confident handhold. Being part of the Sliding Door Hardware product class and the Sliding Door Pulls category ties this handle directly to sliding door use rather than hinged doors, which helps align it with hardware schedules that separate swing and sliding openings. The product name identifies it as a door handle rather than a cabinet knob or small pull, supporting use on larger doors where a substantial pull length is preferred.
The web description states this internal rounded stainless steel handle is for use with DSI mounting kits, which ties its mounting interface directly to that system so installers can match the handle to DSI-specific fastening components. Posts for internal handles are described as having set screws for DSI mounting kits, meaning the internal handle secures to the DSI mounting interface by clamping onto kit components rather than relying on through-threaded posts, which simplifies final handle alignment on the interior face of a sliding door. The 500 mm center to center dimension also defines the post spacing, giving a clear drilling layout reference when positioning the related DSI mounting kit on the door panel for a precise, repeatable installation.
The product is classified as Sliding Door Hardware and placed within the Sliding Door Pulls category, which positions this internal handle as part of the operating side of a sliding door assembly rather than a decorative trim piece. Its 500 mm center to center length spreads the user grip across a wide section of the door, which helps users draw the door along its track with controlled force, especially when the door panel has substantial height. The internal handle is specifically noted as having posts with set screws for DSI mounting kits, so on the room side where this handle is used, the handle clamps onto the DSI kit interface, providing a secure pull without exposed bolt heads on the gripping surface. The internal rounded stainless steel description indicates that the user-facing geometry is rounded, offering a comfortable hand contact area for repeated pulls over the life of the installation.
The web description also states that posts for external handles are threaded to accept screws, while posts for internal handles have set screws for DSI mounting kits, so an opening using both internal and external pulls can maintain a coordinated look while using different post interfaces tailored to each side. The similar style to 16 and 27 series cabinet handles allows designers to carry one visual language from cabinet fronts to adjacent sliding doors, aligning sightlines across casework and door systems in the same room. The satin SS finish on 304 stainless steel combines a brushed appearance with a corrosion-resistant base metal, which keeps the handle surface looking uniform under typical interior conditions where doors are touched frequently. The 500 mm center to center dimension also sets a consistent visual scale, so multiple sliding doors along a wall can share matching handle spacing and handle lengths, creating an orderly appearance.
The handle is categorized as Sliding Door Hardware in the Sliding Door Pulls category, so it is intended for use on sliding door applications rather than hinged doors.
The 500 mm center to center measurement defines the distance between mounting posts, giving a clear drilling layout and providing a long gripping span on the sliding door surface.
The web description specifies it is for use with DSI mounting kits and that posts for internal handles have set screws, so it attaches by clamping to the corresponding DSI mounting interface.
The handle uses 304 stainless steel with a satin SS finish, providing a corrosion-resistant base metal and a low-glare surface suitable for interior sliding doors.
The web description notes a similar style to 16 and 27 series cabinet handles, so sliding doors can visually match nearby casework fitted with those series.
The handle is branded Sugatsune America and listed as Sliding Door Hardware, aligning it with a defined builders hardware line for sliding door projects.
This internal rounded stainless steel 500 mm center to center handle from Sugatsune America is defined for sliding door use within the DSI system, giving projects a clearly specified internal pull that matches DSI mounting kits. The 304 stainless steel material with satin SS finish delivers a corrosion-resistant, low-glare surface suited to interior sliding doors that see regular traffic. With the posts for internal handles using set screws for DSI mounting kits, installers get a handle designed around that interface rather than a generic pull. For sliding door work where a 500 mm center to center internal handle is called out by part number DSI-3330-30-50I, this piece aligns with the described DSI sliding door hardware setup.
