Hettich 20 inch full extension soft-close drawer slides provide a complete opening stroke, so the drawer travels fully out of the cabinet and exposes the usable interior space for easier access during everyday use or installation adjustments. The integrated Silent System in this KA 5632 series soft-close ball bearing runner controls the closing motion, so the drawer is drawn in smoothly at the end of travel, which helps reduce slam forces on the cabinet and drawer joints. A full extension runner design in a side mount configuration positions the slide along the drawer sides, which keeps the mounting approach familiar for installers working with standard side-mount drawer construction. Ball bearing construction supports precision control for smooth running action, translating finger pressure at the handle into consistent movement across the slide length. High lateral stability in the runner helps the drawer track straight, which matters when drawers carry weight or when face gaps need to remain visually even.
The Hettich America Corporation KA 5632 series runner is designed as a side mount slide, positioning along the drawer sides and cabinet interior walls, which works with drawer boxes built around side-mount dimensions and clearances. The full extension function means the active member travels completely out from the cabinet body, which gives direct sight to screw locations and clearances while setting the drawer and verifying slide engagement. The unhanded configuration means the same part number 9221511 serves on either side, which simplifies layout and orientation when working through multiple drawers in a bank. Integrated Silent System soft-close behavior is built into the runner, so the closing assistance is part of the same component that controls motion, reducing separate mechanisms to coordinate during installation and adjustment.
The Hettich KA 5632 series full extension runner is specified for drawers with grooved, rebated, or flush fitted drawer bottom panels, so the slide supports common drawer box construction methods used in cabinet shops and woodworking operations. A design that works with grooved bottoms fits drawer boxes where the panel sits in a groove in the sides, while support for rebated bottoms works with stepped or housed bottom panels, and compatibility with flush fitted bottom panels suits drawers where the bottom is level with the underside of the sides, broadening how these slides integrate into existing construction standards. Load capacity to EN 15338 Level 2 gives the runner a defined performance class under a European drawer runner standard, which signals that the slide is built and tested to support typical residential or light commercial drawer loads under that level. Galvanized steel construction provides a zinc-coated steel runner body, so the slide delivers the rigidity of steel along with a treated surface intended to resist corrosion in normal cabinet and furniture interior conditions. For installers and shops standardizing on Hettich America Corporation hardware, the manufacturer part number 9221511 directly identifies this 20 inch KA 5632 soft-close full extension slide, which simplifies ordering and matching runners across projects or service work.
The full extension ball bearing design offers precision control for smooth running action, so when the drawer is pulled, the ball bearings guide the movement along the complete stroke, giving a uniform feel that helps drawers in a bank move consistently from one opening to the next. High lateral stability in the runner limits side deflection under load, which keeps drawer faces tracking square in the cabinet opening and supports maintaining consistent reveals between adjacent fronts without repeated tweaking. The integrated Silent System release catch allows the drawer to separate quickly from the cabinet body, so the installer can remove the drawer box for adjustments, drilling, or interior cabinet work, then re-engage it on the runners without disturbing the slide positions. Because the Silent System is integrated into the same runner that provides soft-close, the decelerated closing and the release catch function tie back to a single component, which reduces the number of unique parts in the assembly and streamlines both installation and later service. The side mount format lines up with widely used drawer and cabinet construction practices, so shops already building side-mount boxes can adopt this KA 5632 runner and gain soft-close and smooth travel behavior without changing drawer bottom styles beyond the supported grooved, rebated, or flush fitted configurations.
The KA 5632 full extension runner is designed for drawers with grooved, rebated, or flush fitted bottom panels, so it works with several common drawer box construction styles.
The integrated Silent System in this soft-close runner manages the final closing distance, guiding the drawer smoothly into the cabinet and reducing end-of-travel impact on the drawer and case.
Full extension on this Hettich runner means the drawer opens to the full slide length, giving clear access to the entire drawer interior and the rear area during use and installation work.
High lateral stability in the runner limits side-to-side play under load, which helps drawers track straight and keeps front gaps more consistent across a run of cabinets.
This KA 5632 drawer runner is unhanded, so the same 9221511 part can be mounted on either the left or right side of the drawer during installation.
This Hettich runner is made from galvanized steel, giving a zinc-coated steel body that combines structural strength with a corrosion-resistant surface for cabinet interiors.
The Hettich KA 5632 20 inch full extension soft-close ball bearing drawer slide brings integrated Silent System, high lateral stability, and precision control into a side mount runner built from galvanized steel. With support for drawers using grooved, rebated, or flush fitted bottom panels, this unhanded slide gives cabinet shops and installers a defined EN 15338 Level 2 load-capacity solution for everyday drawer applications. Use the 9221511 part identification when specifying or reordering so the same KA 5632 runner performance carries through across cabinet runs and repeat projects.
