Grass Maxcess 21 Inch Undermount Slides For Smooth Use

Grass Maxcess 21 inch undermount drawer slides use an economical 7/8 extension concealed design that supports everyday cabinet drawers while keeping hardware out of sight, which helps built-ins and kitchen runs present a clean, finished look. These Grass America slides provide liquid dampening for continuous smooth closing action, so drawers travel in a controlled way right to shut position, which helps reduce slamming in busy kitchens, shops, or office cabinetry. The undermount drawer slides are designed for use with 5/8 inch, or 16 mm, drawer side thickness, which simplifies planning when cases and drawer boxes are built around standard stock. A patented load bearing support roller works with the runner system to carry the drawer, which helps the slide track stay stable under changing loads. The slides are rated for a 75 lb dynamic load capacity, so drawers can carry typical residential or light commercial contents while still operating within the slide design limits.

Key Slide Details That Support Cabinet Builds

• The 7/8 extension concealed drawer slide design lets most of the drawer open while hiding the hardware under the box, which helps projects where appearance and uncluttered cabinet lines matter.
• Liquid dampening in the slide provides continuous smooth closing action through the final travel, which helps drawers close quietly and reduces impact on the cabinet front and joinery over time.
• Design for use with 5/8 inch, or 16 mm, drawer side thickness aligns with common drawer box material sizes, which helps streamline cutting lists and reduces layout changes between jobs.
• The patented load bearing support roller carries the moving load along the undermount track, which supports consistent movement when drawers are filled and helps reduce racking during use.
• A 75 lb dynamic load capacity rating gives the slide enough strength for typical kitchen, bath, and furniture drawers, which helps the hardware handle everyday contents without overstressing the runners.
• Meets and exceeds ANSI/BHMA 156.9, Grade 1, which signals that the undermount slide has been performance tested for cycle life and load under standardized conditions.

Installation Considerations For Undermount Face Frame Use

These Grass Maxcess undermount drawer slides are identified in the description as 21 inch full access Maxcess for face frame, which aligns them with cabinet runs built around a face frame construction method. The undermount drawer slide configuration places the runners beneath the drawer box rather than on the sides, which influences how builders size the drawer width and position mounting brackets relative to the face frame opening. Design for a 5/8 inch, or 16 mm, drawer side thickness guides the side clearance and notch layout at the back of the drawer box, which helps the hardware engage properly along the length of the slide. The 7/8 extension travel means the slide does not fully overtravel past the cabinet front, which can be useful where adjacent doors, hardware, or walkways limit how far drawers should project when open.

Where These Undermount Slides Are Typically Applied

The SAP description notes 21 inch full access Maxcess for face frame, which positions these Grass America undermount slides for face frame cabinet work where drawer depths match a 21 inch nominal length. The undermount drawer slides category and product class confirm that the hardware is intended as the primary runner system beneath the drawer box, which fits kitchen, bath, and furniture builds that call for concealed slides. A 75 lb dynamic load capacity suits drawers storing dinnerware, utensils, linens, or office items, which keeps usage within the tested load envelope for the slide. Because the design is for 5/8 inch, or 16 mm, drawer side thickness, the slides align well with drawer boxes cut from that stock size, which helps production shops keep consistent tooling and joinery settings across multiple cabinets.

How Slide Features Support Consistent Drawer Performance

The liquid dampening built into these undermount drawer slides provides continuous smooth closing action from the point the soft-close engages through final travel, which helps drawers feel controlled and finished on every cycle. A patented load bearing support roller supports the moving drawer along the track, which distributes weight and helps reduce sag or binding as drawers are opened and closed under load. The 7/8 extension design strikes a balance between access and space, letting most of the drawer clear the cabinet front while retaining enough engagement in the slide for stable tracking. Meeting and exceeding ANSI/BHMA 156.9, Grade 1, means the Grass Maxcess slide has been evaluated under industry testing for strength and cycle life, which supports confidence that the hardware can stand up to repeated residential or light commercial use. The Grass 13305-03 designation ties all of these details to a specific manufacturer part number, which helps match replacement slides or specify identical hardware across a project.
