    Description

    Grass Maxcess Undermount Drawer Slides For Face Frames

    Grass Maxcess undermount drawer slides provide an economical 7/8 extension concealed drawer slide with liquid dampening, so drawers close in a smooth, controlled motion that suits everyday cabinet use. The 21 inch length supports standard kitchen, bath, and utility drawer depths where full access is not required but consistent closing action is important. Their soft-close function is driven by the liquid dampening design, which manages closing speed and reduces impact at the cabinet. As an undermount solution, the slide mounts beneath the drawer, keeping hardware out of sight while still carrying the load. This model is built for face frame construction, matching common cabinet builds that rely on a front frame for structure. By combining concealed mounting, soft closing, and application to face frame cabinets, these slides support a finished look with repeatable performance.

    Key Grass Maxcess Details For Daily Cabinet Use

    • The economical 7/8 extension design supports partially opening drawers, which suits storage where full-depth access is less critical and cost control is a factor on multi-drawer projects.
    • The concealed undermount configuration keeps the slides hidden under the drawer box, which maintains a clean interior and exterior appearance while still providing guided movement.
    • Liquid dampening manages closing speed, which helps drawers settle quietly against the cabinet front and reduces the abrupt contact associated with non-dampened slides.
    • The patented load bearing support roller carries moving loads, which supports smooth travel under weight and helps the drawer track consistently along the slide path.
    • A 75 lb dynamic load capacity is rated for drawers under motion, which supports typical residential cabinet contents where the drawer is opened and closed repeatedly.
    • Testing to meet and exceed ANSI/BHMA 156.9, Grade 1 provides a recognized performance benchmark, which matters on projects that rely on standardized hardware durability criteria.

    Installation Fit For 5/8 Inch Face Frame Drawers

    These Grass Maxcess 21 inch soft-close 7/8 extension undermount drawer slides are designed for use with 5/8 inch (16 mm) drawer side thickness, so drawer box construction needs to match that dimension for proper engagement with the slide hardware. The face frame construction requirement means the slide geometry is arranged to work with a cabinet that has a front frame, which affects how the slide aligns from the frame back into the interior. As undermount slides, they locate beneath the drawer rather than on the side, influencing how the drawer box is sized and notched relative to the cabinet opening. When the drawer side thickness, undermount positioning, and face frame layout align to these details, the slide can travel correctly within its 7/8 extension range and deliver its soft-close action.

    Using Grass Maxcess Slides In Cabinet Projects

    Where Grass Maxcess Undermount Slides Are Applied

    The Grass Maxcess 21 inch soft-close 7/8 extension undermount drawer slides, roller bearing zinc - 13305-12 are specified for face frame construction, so they integrate into cabinets that use a structural front frame around the opening. Within that cabinet style, their 21 inch length positions them for drawers sized to that depth range, common in kitchen base, bathroom vanity, and utility cabinetry layouts that accept a 21 inch slide. The design is for use with 5/8 inch (16 mm) drawer side thickness, which directs how drawer sides, backs, and fronts are dimensioned so the undermount hardware seats correctly under the box. Because these are concealed undermount slides, they sit below the drawer, which supports applications that prioritize a clean side view and uninterrupted interior surfaces, such as higher-end residential cabinetry or built-in furniture that benefits from hidden slide hardware.

    Details That Support Consistent Drawer Performance

    The liquid dampening in these Grass America slides provides continuous smooth closing action, which supports drawer fronts meeting face frames in a controlled way instead of slamming. That smooth action is reinforced by a patented load bearing support roller, which carries dynamic loads as the drawer moves, supporting consistent feel from empty drawers up to the rated load. The 75 lb dynamic load capacity refers to performance while the drawer is in motion, so the slide system is arranged to hold common drawer contents at speed without binding. The 7/8 extension travel limits how far the drawer projects from the cabinet, which can help manage clearances in tight corridors or smaller rooms where full extension could interfere with adjacent features. By meeting and exceeding ANSI/BHMA 156.9, Grade 1, these undermount slides follow a standardized durability and performance level, which supports their use in projects where hardware is expected to cycle repetitively while maintaining the same closing characteristics over time.

    Common Questions About Grass Maxcess Undermount Slides

    What drawer side thickness do these slides support?

    The Grass Maxcess undermount drawer slides are for use with 5/8 inch (16 mm) drawer side thickness, so drawer box construction follows that dimension for proper slide engagement under the sides.

    Are these slides designed for face frame cabinets?

    The Grass Maxcess 13305-12 slides are specified for face frame construction, meaning their layout aligns to cabinets that use a front frame around the drawer opening.

    How far do the Grass Maxcess slides extend?

    The Grass Maxcess undermount slides provide 7/8 extension, so the drawer opens most of its length while retaining a short section within the cabinet for guided travel.

    What load rating do these undermount slides carry?

    The Grass Maxcess 21 inch undermount drawer slides have a 75 lb dynamic load capacity, supporting typical drawer contents while the drawer is opened and closed in normal use.

    Do these Grass slides provide soft-close action?

    The Grass Maxcess undermount slides use liquid dampening for continuous smooth closing action, so the drawer is guided gently to the face frame during the final travel.

    What performance standard do these slides meet?

    The Grass Maxcess 13305-12 slides meet and exceed ANSI/BHMA 156.9, Grade 1, providing a defined benchmark for cycle performance and functional durability in drawer slide use.
