Grass Maxcess 15" Soft-Close 7/8 Extension Undermount Drawer Slides, Roller Bearing Zinc - 13303-03

Grass Maxcess 15 Inch Drawer Slides For Face Frames

Grass Maxcess 15 inch drawer slides give face frame cabinets a concealed undermount option that stays out of sight while carrying the drawer. The 7/8 extension design lets the drawer open far enough for everyday access while keeping the slide protected inside the cabinet. Soft-close action is handled by liquid dampening, which slows the drawer smoothly at the end of travel so it settles into the cabinet without slamming. As an undermount drawer slide, it supports the drawer from below, which helps keep the interior clear for storage. This model is part of the Grass Maxcess line from Grass America, so it follows their hardware standards for face frame construction. The slide is designed for use with 5/8 inch, or 16 mm, drawer side thickness, which gives a clear target when building or selecting drawer boxes for these slides.

Key Grass 13303C-03 Slide Details In Practice

• The 7/8 extension concealed drawer slide layout moves the drawer almost fully out of the cabinet while leaving a small portion engaged, which helps support the load and guides the motion during opening and closing.
• Liquid dampening creates continuous smooth closing action by absorbing drawer momentum at the end of stroke, which reduces impact on the cabinet and helps drawer fronts land consistently against the face frame.
• Design for 5/8 inch, or 16 mm, drawer side thickness means drawer box construction can be planned around a known side dimension, which simplifies machining and keeps the undermount engagement points aligned.
• Configuration for face frame construction matches common cabinet builds that step from a front frame into the interior, so the slide geometry is suited to that layout during installation.
• A patented load bearing support roller carries the moving weight along the slide path, which supports the drawer under load and helps the motion stay stable instead of dragging on the metal members.
• The 75 lb dynamic load capacity rating defines the maximum tested moving load, so drawer contents can be planned within that range without overloading the slide mechanism.
• Compliance with ANSI/BHMA 156.9, Grade 1 indicates the slide has been tested against an established hardware standard, which speaks directly to performance expectations in normal drawer use.

Face Frame Undermount Installation Considerations

This Grass Maxcess undermount drawer slide is specified for face frame construction, so its geometry is arranged to work with a front frame that stands proud of the cabinet interior. Using a slide meant for face frames helps the moving members clear the frame while still supporting the drawer box from below. The requirement for 5/8 inch, or 16 mm, drawer side thickness ties directly into how the undermount mechanisms engage under the drawer, so building to that thickness keeps the interface secure. The 15 inch length defines the cabinet depth range where this model fits, guiding cabinet design and drawer sizing for the run.

Where These Slides Work And Why Details Matter

Using Grass Maxcess Undermount Slides In Cabinets

In a cabinet with face frame construction, these Grass Maxcess 15 inch soft-close 7/8 extension undermount drawer slides sit beneath the drawer so the hardware stays hidden when the drawer is open. The concealed layout helps present a clean interior while the metal members and support roller do the structural work below the box. Because the slides are configured around 5/8 inch, or 16 mm, drawer sides, that dimension becomes the reference for building or choosing drawer boxes that will sit correctly on the undermount interface. The 7/8 extension motion brings the drawer out far enough for access to stored items while a small portion of the slide remains engaged, which supports the moving weight as it travels in and out of the cabinet.

Why Load Rating, Dampening, And Standards Matter

The 75 lb dynamic load capacity on these Grass 13303C-03 drawer slides sets a clear performance envelope for moving loads, so drawers can be stocked for typical household or shop use without exceeding what the hardware is designed to handle. The patented load bearing support roller carries that moving weight along the length of the slide, which helps prevent binding and keeps the action smoother over time as the drawer is opened and closed repeatedly. Liquid dampening turns that motion into a soft-close action by catching the drawer in the final portion of travel, which lowers closing noise and helps drawer fronts meet the face frame in a controlled way. Because the slide meets and exceeds ANSI/BHMA 156.9, Grade 1, it has been evaluated to a recognized standard for drawer slides, which supports confidence in its use across many cabinets that rely on consistent opening and closing behavior.
