Hettich 20" Over Travel Standard Ball Bearing Drawer Slides KA 4620 Series, Unhanded Side Mount Zinc - 9019958

Hettich KA 4620 Drawer Slides For Smooth Over Travel

Hettich KA 4620 drawer slides are 20 inch, over extension, side mount ball bearing runners that support drawers moving smoothly beyond the cabinet front. This over extension runner with pull-out stop and roll-out prevention lets the drawer travel further out while still being held securely, which improves access to contents and keeps the drawer from unintentionally coming free under full extension. Unhanded side mount design lets the same slide work on either side of the drawer, which streamlines layout and keeps left-right planning simple on the bench. Dimensions of 58mm x 19mm x 500mm (H x W x L) define the slide envelope, so installers can design or verify clearances around the runner for consistent fit across multiple cabinets.

Key KA 4620 Details That Support Daily Use

• Over extension runner with pull-out stop and roll-out prevention lets the drawer extend beyond the cabinet face while retaining control, which helps during loading, unloading, and working at the cabinet without unexpected drawer release.
• Release catch for quickly separating drawer from cabinet body allows the drawer to be removed without tools, which speeds installation, fitting, and later service when adjusting or working on the cabinet interior.
• Precision control for moving smoothly and freely and high lateral stability keeps the drawer running true on its ball bearings, which reduces side play and helps fronts stay aligned in face frame or frameless layouts.
• Dimensions of 58mm x 19mm x 500mm (H x W x L) provide a defined runner profile, which helps when setting up drawer box sizes, reveal gaps, and runner spacing in production or custom work.
• Load capacity to EN 15338, Level 1 establishes a tested performance level, which gives a defined reference for using the slide in everyday furniture or cabinetry within that load range.
• Galvanised steel, blue passivated construction provides a zinc-treated surface, which supports corrosion resistance in typical indoor woodworking environments such as kitchens, offices, and residential furniture.

Side Mount Drawer Slide Fit And Release Details

The unhanded side mount configuration lets the KA 4620 slide fix to either cabinet side, which simplifies ordering and layout for production runs or field work. For drawers with grooved, rebated or flush fitted drawer bottom panel, the runner is intended to support these common drawer constructions, which helps when standardizing box designs across multiple jobs. The release catch built into the mechanism separates the drawer from the cabinet body quickly, which is useful during templating, finishing, and final fitting stages. Over extension capability combined with a pull-out stop and roll-out prevention supports full access while helping maintain control of the drawer travel during normal operation.

Where KA 4620 Slides Work And Why Details Matter

Applications With Grooved Or Flush Drawer Bottoms

The KA4620 slide is specified for drawers with grooved, rebated or flush fitted drawer bottom panel, which ties directly to how many cabinet shops build boxes for kitchens, baths, and furniture pieces. This compatibility with common bottom panel styles lets the same runner work across different lines without changing joinery methods, which supports consistent tooling and jig setups in the shop. Side mount, ball bearing construction aligns with installations where the slide is fixed to the cabinet side, which fits both frameless and many face frame cabinets that are designed around side-mounted runners. Over extension runner behavior means the drawer front projects beyond the cabinet face when fully open, which improves visibility and hand access to items stored at the back of the drawer cavity.

The pull-out stop and roll-out prevention features act directly on that extended travel by holding the drawer on the runners at full extension, which matters when drawers are loaded and are frequently opened to their limit. Precision control for moving smoothly and freely and high lateral stability work together so the drawer tracks straight without racking, which helps keep front gaps even and reduces binding against the cabinet. By following EN 15338, Level 1 for load capacity, the slide references a recognized furniture standard, which supports predictable performance when matching everyday loading expectations to the slide selection. The galvanised steel, blue passivated finish provides a zinc-based protective layer, which helps the slide maintain function and appearance in typical interior environments where moisture and wear are present over time.

Support For Repeatable Side Mount Installations

The 58mm height and 19mm width define the runner size, which lets installers plan drawer and cabinet clearances so multiple units line up consistently in banks of drawers. Length of 500mm, corresponding to 20 inch nominal length, ties into common cabinet depth planning, which makes it easier to integrate these runners into standard carcass dimensions. The unhanded design avoids separate left and right parts, which streamlines stock management and reduces potential mix-ups during assembly on the bench or on site. The release catch that separates the drawer from the cabinet body allows drawer boxes to be removed in seconds, which supports finishing, transport, and later adjustments without dismantling the entire slide.

High lateral stability in the ball bearing runner resists side-to-side movement under load, which helps drawers stay aligned when opened quickly or when weight is unevenly distributed. Over extension with controlled pull-out allows drawers to project fully while remaining guided on the slide members, which is important when fitting hardware on deep drawers where back access would otherwise be limited. Because the slide is specified for drawers with grooved, rebated or flush fitted drawer bottom panel, shops can design a single drawer construction method around this runner, which supports repeatable machining and efficient production setups on CNC or traditional equipment.
