Blum 563H TANDEM 18 Soft Close Undermount Slides

Blum 563H TANDEM 18 soft close undermount slides are full extension concealed drawer runners, so the drawer opens fully while the hardware stays hidden under the box, giving clear access to contents and a clean cabinet interior. BLUMOTION soft closing is built into the runners, so drawers close gently, which helps protect fronts and reduces impact on the cabinet. The TANDEM smooth running action keeps motion consistent along the entire travel, which supports precise alignment in kitchen, bath, or shop projects. These undermount drawer slides are part of the 563H TANDEM BLUMOTION line, so they follow a known platform that installers can repeat across multiple cabinet runs. The slides are made in the USA with domestic and European components, so sourcing stays consistent for repeat jobs.

Key Blum 563H TANDEM 18 Slide Advantages

• Full extension concealed drawer runners let the drawer pull completely out while the hardware stays out of sight, which gives end users better access and a clean look in higher-end cabinetry.
• BLUMOTION soft closing is integrated into the slide, so the closing force is controlled at the end of travel, which helps reduce slamming and wear on drawer fronts and face frames during regular use.
• TANDEM smooth running action supports even motion from closed to fully open, which helps drawers feel consistent across a kitchen or bank of cabinets and makes alignment easier to verify during install.
• Four dimensional adjustment is built into the system, so the drawer position can be fine-tuned in multiple directions, which helps dial in reveals and correct minor cabinet or drawer box variations.
• Elongated holes for depth adjustment give front-to-back play during mounting, which helps align drawer fronts with neighboring doors or drawers without re-drilling the cabinet.

Installation, Cabinet Fit, And Drawer Sizing Details

These 18 inch 563H TANDEM BLUMOTION full extension slides are sized for 18 inch drawer applications, so they suit cabinets designed around that nominal depth. The runners work in face frame or panel cabinets, which lets shops standardize on one platform across framed and frameless lines. A 1/2 inch to 5/8 inch drawer thickness range is specified, so drawer boxes built within that side range fit the undermount engagement properly. The slides carry a 100 lb static load capacity and a 90 lb dynamic capacity, which supports typical kitchen and bath drawer storage under normal use. Available lengths in the series range from 9 inches to 21 inches, so projects using these slides can keep the same action across shallow and deep drawers.

Where These Full Extension Runners Are Applied

These full extension concealed drawer runners fit undermount drawer slide applications where a clean look and smooth travel are important, such as residential cabinetry or shop fixtures using face frame or panel cabinet construction. Because the system supports 1/2 inch to 5/8 inch drawer thickness, shops that standardize drawer side stock within this band can apply the same 563H TANDEM BLUMOTION setup across many cabinet widths without changing slide families. The 18 inch length suits typical base cabinet depths, so it works well in kitchen and bath layouts built around standard carcass dimensions. With load ratings of 100 lb static and 90 lb dynamic, these runners handle everyday storage loads within that range, which fits common drawer contents in residential and light commercial work.

Details That Support Alignment And Repeatable Results

Four dimensional adjustment in the Blum 563H TANDEM system allows fine-tuning the drawer position in several directions, which is especially useful when cabinet openings are slightly out of square, helping to keep reveals tight and consistent across a run. Elongated holes for depth adjustment give extra front-to-back movement during installation, so installers can shift the runner position to bring drawer fronts flush with surrounding doors or finished end panels. Bottom mount holes on the 18 inch length define a repeatable fixing pattern from job to job, which reduces layout time when running multiple identical drawer boxes. The TANDEM smooth running action supports a stable feel when drawers are loaded within the 90 lb dynamic capacity, which helps prevent binding over time. BLUMOTION soft closing engages near the end of travel, so fronts contact frames and panels gently, which supports long-term appearance in frequently used drawers.
