Hettich 350mm soft-close undermount drawer slide defines this right hand Quadro runner as a 350 mm long partial extension slide designed for undermount drawer applications, so it supports compact drawer depths often used in kitchen, bath, and furniture projects. The soft-close function comes from the integrated Silent System, which gently controls closing motion, so drawers are pulled shut in a controlled way that protects fronts and reduces impact on the cabinet. The runner is classified as a partial extension slide, so the drawer does not travel fully out of the cabinet, which suits installations where full access is not required but smooth access to contents near the front is important. As an undermount drawer slide, it supports a clean drawer-box appearance because the hardware is positioned under the drawer rather than on the sides, which helps preserve interior width for storage.
The slide on installation with catches defines a mounting method where the drawer box engages the undermount runner using slide-on fittings, so installing or removing the drawer can be done without complex fastener steps at the rail itself. Tool-less height adjustment is built into the system, so vertical positioning of the drawer front can be altered without separate tools, which helps align fronts across a run of cabinets after the drawers are already in place. The system is suitable for drawers with a side profile thickness of up to 16 mm, so drawer box construction using sides at or below this thickness fits the runner geometry for proper engagement. The Quadro platform concept uses identical cabinet body, drawer, and front panel dimensions for both Quadro partial and full extension runners for slide on installation, so designers can standardize cabinet and drawer sizing while changing only the runner type.
This undermount drawer slide is part of the Hettich Quadro platform, so it works in cabinet bodies designed around that runner family, allowing consistent layout across partial and full extension projects that use the same basic carcass geometry. The 350 mm length points toward medium-depth drawers, so it suits smaller base cabinets, upper cabinets, or furniture pieces where a deeper runner would conflict with cabinet depth. Because the drawer side profile can be up to 16 mm thick, it matches common metric-based drawer constructions using board materials close to that thickness, keeping the runner engagement secure under the drawer. The right hand designation clarifies that this unit installs on the right underside of the drawer box, so when paired with the proper left-hand runner, the drawer tracks straight during opening and closing.
The integrated Silent System soft-close feature controls the last portion of drawer travel, so even when the drawer is pushed in firmly, the mechanism catches and pulls it quietly to a stop, which reduces stress on drawer fronts and face frames over time. The EN 15338, Level 3 load capacity rating of 48.5 lb. ties performance to a recognized furniture hardware standard, so drawers loaded within that value can be designed around a repeatable performance benchmark. The ball bearing construction inside the runner carries that rated load on rolling elements, so drawers feel smooth under everyday use instead of dragging along fixed contact surfaces. The Quadro platform concept, using identical cabinet body, drawer, and front panel dimensions for both partial and full extension runners for slide on installation, means a shop can change from partial extension to full extension solutions within the same series without redrawing cabinet cases. The galvanized steel material gives the slide a zinc-coated steel body, so it supports long-term service in typical interior woodworking environments such as kitchens, bathrooms, and offices where controlled humidity is expected.
The Hettich 9105670 is a 350 mm partial extension undermount drawer slide with ball bearings, so it mounts under the drawer and provides smooth, controlled movement.
The integrated Silent System adds a soft-close function, so the drawer is gently pulled shut at the end of travel, reducing slamming and impact on fronts and cabinet frames.
This Quadro runner is suitable for drawers with a side profile thickness of up to 16 mm, so drawer materials at or below that thickness align properly with the undermount hardware.
The 350 mm right hand slide has a load capacity to EN 15338, Level 3 at 48.5 lb., so drawer designs can be planned around that maximum operational load.
Tool-less height adjustment lets the installer shift the drawer vertically without tools, so aligning drawer fronts across a cabinet run can be done quickly after mounting.
The Quadro platform concept keeps cabinet body, drawer, and front panel dimensions identical for partial and full extension runners, so layouts remain consistent while changing runner types.
The Hettich 350mm soft-close undermount drawer slide combines partial extension travel, a right hand Quadro design, and a 48.5 lb. capacity, so it suits medium-depth drawers that need controlled closing in kitchens, baths, and furniture projects. The slide on installation with catches and tool-less height adjustment supports efficient fitting and front alignment, so shop and field teams can work from a consistent cabinet design while dialing in final reveals. For projects built around drawers with side profiles up to 16 mm and galvanized steel undermount runners, this 9105670 model provides a defined specification that fits directly into EN 15338, Level 3 rated installations.
