Full Extension Reach and a Clean White Finish for Shallow Drawer Runs

The Grass ZBox 6423 is a complete steel drawer side and slide kit in White Epoxy, sized for 15-3/4 inch nominal length applications with a 9 inch side height. Rated at 100 lb capacity and built for full extension, it suits compact drawer runs in painted kitchen layouts, bath vanities, and utility cabinetry where a crisp white interior finish is part of the design intent.

Key Features

• White Epoxy finish on the steel profiles creates a clean, matched look inside painted white or light-colored cabinet boxes.
• 100 lb weight capacity supports a fully loaded shallow drawer without sag or drag.
• Full extension brings the entire drawer out to the cabinet face so nothing hides at the back.
• 9 inch side height offers enough wall to retain drawer contents in a compact profile suited to standard-depth cabinetry.
• Steel construction throughout the side profiles and running gear delivers lasting structural rigidity.
• ZBox 6423 platform pairs sides and integrated runners as one engineered system, not a loose slide bolted to a wood box.

Where a 15-3/4 Inch White System Earns Its Place

At 15-3/4 inches nominal length, this kit targets the shallow end of kitchen and bath drawer configurations: spice drawers beside an appliance column, narrow utility drawers in a vanity, or the short upper drawers in a base cabinet stack. Full extension matters especially in these tight spaces because reaching to the back of a shorter drawer without pulling it all the way out is frustrating. With this system the entire drawer box travels out to the face, so contents stay accessible.

The White Epoxy finish is the design driver here. In an all-white painted kitchen or a bath vanity with a white lacquer interior, a bare steel or zinc slide reads as a mismatch the moment the drawer opens. A white-finished system keeps the interior consistent from front to back — a detail that matters to designers specifying handleless fronts where the drawer interior is more visible than usual.

Steel System, Factory Finish, Ready for Production

The ZBox 6423 is a metal drawer system: the steel side profiles are structural, carrying the load and integrating the running gear in one wall. That means no separate slide to mount on a wood box, no alignment step between box and runner, and no mismatch between box rigidity and slide capacity. Steel sides hold their geometry under load better than wood drawer stock, and at 100 lb capacity this system handles a full cutlery drawer or a stocked bath drawer without issue.

The White Epoxy coating is applied at the factory. The finish is consistent across the profile faces, inside and out, which simplifies finishing schedules in production shops — the box arrives ready to receive the front, no touch-up required at the color line.

Right for Painted Interiors and Short-Run Cabinetry

Cabinet shops building painted kitchen lines or bath vanity programs in volume will find the White Epoxy ZBox a natural fit for the shorter drawer positions in those layouts. Designers working with white or light-gray interiors benefit from the finish consistency. Homeowners renovating a kitchen who want the inside of their drawers to look as considered as the outside will appreciate that the white finish extends all the way to the back of the box. Build the drawer front and bottom to the ZBox 6423's published cutting dimensions, pair with the appropriate Grass front fixing brackets for this system, and the drawer is ready to hang.

A White Finish Worth Specifying

When the interior of the cabinet is part of the design, reach for the finish that keeps it consistent. The ZBox 6423 in White Epoxy closes the gap between the painted box and the runner, so the drawer looks right from any angle.
