Knape and Vogt Samet 21" Soft-Close Full Extension Undermount Drawer Slides, Zinc - KVSUMB 904 21

Knape And Vogt Samet Undermount Slides For Drawers

Knape and Vogt Samet undermount drawer slides KVSUMB 904 21 support soft close system with adapting damping, so drawers close smoothly and consistently, which helps protect drawer fronts and reduces impact on cabinet construction in everyday use.

These soft-close full extension undermount drawer slides extend fully, giving access to the entire drawer box depth, which helps installers and users reach items at the back without redesigning cabinet layouts.

The slides are designed for 21 inch drawer applications, aligning with standard cabinet depths, so shops can integrate them into common base cabinet configurations without changing typical carcass dimensions.

Dynamic load capacity of 66 lb (30 kg) supports medium-duty drawer contents, so these slides work in many residential and light commercial cabinet applications where balanced strength and smooth travel are needed.

The system exceeds ANSI/BHMA A156.9-2010 technical specifications, which signals performance that meets recognized industry criteria important to professional shops delivering repeatable results across multiple installations.

Key Working Advantages Of These Undermount Slides

• The soft close system with adapting damping controls closing speed, so drawers are pulled in quietly and securely, which helps reduce slamming and stress on joinery over time in regular cabinet use.
• Full extension with synchronization travel keeps both slide members moving together, which supports stable drawer motion and helps minimize racking when drawers are opened to their full depth under typical load conditions.
• Maximum drawer box material thickness of 5/8 inch (16 mm) defines side material choice, allowing fabricators to design drawer boxes confidently around this thickness for consistent fit with the undermount hardware.
• Minimum inside drawer width of 8-5/32 inch (207 mm) sets a clear lower limit, so designers can size narrow drawers while maintaining the clearance these slides require to function properly on both sides.
• Dynamic load capacity rated at 66 lb (30 kg) guides where to use these slides, supporting common kitchen, bath, and utility drawers holding everyday items without overbuilding for light to medium storage needs.
• Exceeds ANSI/BHMA A156.9-2010 technical specifications, which indicates the slides have been built to meet demanding performance benchmarks valued in professional cabinetry projects.

Installation, Fit, And Adjustment Details On Site

These undermount drawer slides are classified as 2D (4-way) micro roller adjustable in height and horizontal directions, giving installers fine-tuning capability up and down and side to side, which helps align drawer fronts precisely with surrounding faces.

Depth adjustment is achieved by elongated holes in slide, so installers can shift the slide position along the cabinet depth, which helps dial in overlay relationships and achieve consistent reveals across a run of drawers.

Smart Lock front locking devices are sold separately, and they interface with the slide system to secure the drawer box to the undermount hardware, which supports straightforward drawer removal and reattachment during fitting or later service.

Tool-less installation is noted in the description, so key engagement steps use built-in mechanisms instead of loose tools at the slide connection points, which can speed production work and reduce setup time at the bench or on site.

Using KVSUMB 904 21 Slides In Cabinet Projects

Where These 21 Inch Undermount Slides Fit Best

The 21 inch Knape and Vogt Samet soft-close full extension undermount drawer slides suit drawer boxes built with maximum drawer box material thickness of 5/8 inch, so they align well with many shop-standard solid wood or panel drawer constructions.

Minimum inside drawer width of 8-5/32 inch sets the lower limit for usable drawer interiors with this hardware, which makes these slides a strong fit for medium-width drawers common in base cabinets, vanities, and general storage units.

Because the dynamic load capacity is 66 lb (30 kg), these slides work effectively in drawers intended for dishware, utensils, linens, or office supplies, where weight stays within this rating and smooth synchronized travel remains a priority.

The soft close system with adapting damping is suited to living spaces and work areas where controlled closure is desired, which supports quieter environments and reduces the wear that repeated hard closing can place on casework joints.

The product class as undermount drawer slides keeps hardware hidden beneath the drawer, which supports clean cabinet interiors and face lines while still delivering full extension with synchronization travel for practical access.

Adjustment Features That Support Repeatable Alignment

The 2D (4-way) micro roller adjustable design provides height (up and down) and horizontal (side-to-side) adjustments, so installers can correct for small variances in cabinet or drawer construction and still produce straight, even reveals across fronts.

Height adjustment lets users raise or lower the drawer box relative to the opening, which is valuable when face frames, inset fronts, or differing bottom clearances demand fine tuning rather than reworking drawer parts or cabinet openings.

Horizontal adjustment side-to-side enables shifting the drawer slightly within the opening, helping align gaps between adjacent fronts and cabinet sides and supporting a uniform visual layout even when case parts vary slightly.

Depth adjustment achieved by elongated holes in slide allows repositioning along the cabinet depth, which helps match drawer front projection to surrounding doors and panels and supports consistent overlay or inset relationships in a bank of drawers.

Soft close system with adapting damping works together with these adjustment options, because controlled closing emphasizes any misalignment, so the fine adjustments help the drawer meet the cabinet uniformly when the damping system engages.

Exceeding ANSI/BHMA A156.9-2010 technical specifications further supports consistent performance across multiple installations, since the tested characteristics behind that standard align with the precision and repeated motion expected in cabinet shop production.
