    Description

    Grass Maxcess Undermount Drawer Slides For Smooth Use

    Grass Maxcess undermount drawer slides are economical 7/8 extension concealed drawer slides with liquid dampening, so drawers travel most of their depth and then slow into a continuous smooth closing action that feels controlled on every use. The soft-close liquid dampening manages the final inches of travel, which reduces slamming and helps protect drawer fronts and cabinet frames during everyday operation. Because the slides are concealed undermounts, the hardware sits out of sight under the drawer, leaving the interior and cabinet sides unobstructed for a cleaner finished look. These slides are 15 inch Grass Maxcess units with a zinc finish, so they match the 13303-12 specification when that exact length and model are required on a job. Designed as part of the Grass America product line, they provide a consistent soft-close action within the Grass Maxcess family across similar installations.

    Key Slide Details That Support Cabinet Work

    • The 7/8 extension design lets most of the drawer box move out while keeping a portion engaged, which supports the drawer under load and helps maintain stable tracking near the fully open position.
    • Concealed undermount construction places the slides beneath the drawer, which keeps hardware hidden from view and leaves the drawer sides clear for straightforward box construction and interior access.
    • Liquid dampening provides continuous smooth closing action, so drawers transition from free travel into a controlled soft-close zone, reducing impact at the stop and helping maintain fit at the face frame over time.
    • The patented load bearing support roller carries drawer weight through the run, which spreads the dynamic load and supports the rated 75 lb dynamic load capacity in everyday cabinet use.
    • A 75 lb dynamic load capacity matched with Grade 1 performance under ANSI/BHMA 156.9 means the slides are engineered to handle typical drawer contents while maintaining function under standardized testing conditions.
    • The Grass Maxcess design is described as economical, which helps control hardware cost across multi-drawer projects while still providing soft-close performance and concealed undermount construction.

    Face Frame Mounting And Drawer Side Details

    These Grass Maxcess 15 inch soft-close 7/8 extension undermount drawer slides are specified for face frame construction, so the geometry is built to align with a face-framed cabinet opening instead of a frameless case. The slides are for use with 5/8 inch, or 16 mm, drawer side thickness, which defines the drawer box material dimension that aligns correctly with the slide hardware. Matching the drawer side thickness to this 5/8 inch requirement positions the drawer properly on the undermount mechanisms, supporting smooth travel and correct front reveal at the face frame once installed. Because the slides are part of the Grass Maxcess undermount range, their layout supports a concealed mount under the drawer, which pairs naturally with face frame cabinet construction where visible side hardware is often avoided.

    Using Grass Maxcess Slides In Real Installations

    Where These 15 Inch Undermount Slides Fit Best

    The Grass Maxcess 15 inch soft-close 7/8 extension undermount drawer slides with roller bearing zinc finish sit in the undermount drawer slide class, so they are used where concealed hardware and smooth travel are priorities. Their design is described as for face frame construction, which aligns them with kitchen, bath, or utility cabinets that are built around a frontal frame instead of a full-overlay carcass. Because the slides are for use with 5/8 inch, or 16 mm, drawer side thickness, they work where the drawer boxes are built from that material gauge, keeping the drawer centered over the undermount mechanisms. The 7/8 extension behavior lets the user access most of the drawer depth while still holding part of the slide nested for support, which is useful on mid-depth drawers that carry regular household or shop contents. With a 75 lb dynamic load capacity, the slides are oriented toward drawers that see active loading and movement rather than purely decorative or very light-duty applications.

    Details That Support Repeatable Drawer Performance

    The Grass Maxcess undermount drawer slides use liquid dampening to create continuous smooth closing action, so each closing cycle moves from free-glide into a controlled soft-close zone without abrupt stops, which supports repeatable feel across a bank of drawers. The patented load bearing support roller shares the load along the slide path, which contributes to stable movement and helps the hardware support its 75 lb dynamic load rating when drawers are filled within that capacity. By meeting and exceeding ANSI/BHMA 156.9, Grade 1, these slides are verified against a recognized standard, so the opening and closing cycles, load, and alignment retention have been tested to performance benchmarks relevant to cabinet work. The 13303-12 manufacturer part number ties these Grass America slides to a specific 15 inch Grass Maxcess configuration, which simplifies matching existing installations or project documents. As an economical concealed undermount option, this model lets a builder or installer standardize on a single soft-close slide across many face frame cabinets that share 5/8 inch drawer side construction.
