Grass America Elite 21" Soft-Close Full Extension 75 lb Undermount Drawer Slide, Zinc, 13365C-03

Soft-Close Full Extension And 5/8 Inch Side Compatibility in a 21 Inch Concealed Runner

The Grass Elite Plus 21 inch undermount drawer slide delivers full-extension travel and integrated soft-close in a concealed roller-bearing design built for drawer boxes with sides up to 5/8 inch thick. It suits both face-frame and frameless cabinet construction, making it a practical choice across a wide range of residential cabinetry work.

Key Features

• Full extension brings the entire 21 inch drawer out to the cabinet face, putting the back of the box within reach.
• Integrated soft-close catches the drawer near the end of travel and settles it shut without slamming.
• 5/8 inch maximum drawer side thickness suits the most common dovetailed and doweled box construction used in production cabinetry.
• Roller-bearing carriage on zinc-finished steel delivers a smooth, quiet pull through years of daily use.
• Compatible with face-frame and frameless cabinets, so one slide works across both cabinet construction types on the same job.

Where This Slide Fits the Work

At 21 inches, this slide covers the drawer depth that shows up most often in standard base cabinet and bath vanity work — long enough for a typical kitchen drawer box, short enough to fit in shallower utility cabinets. Full extension means nothing stays hidden at the back: pots and pans, utensils, deep pantry contents, and file folders all come fully out to the opening. The soft-close mechanism handles the close without any input from the user, which matters in kitchens and baths where hands are frequently occupied or wet.

For face-frame cabinets, the rear of the slide needs support from the matching Elite Plus series rear mounting brackets — those are sold separately and are series-specific, so they cannot be swapped for brackets from another system. In frameless cabinets, the slide mounts directly to the cabinet side panel without additional rear hardware.

Construction and Finish

The slide runs on a roller-bearing carriage inside zinc-plated steel members. Zinc plating protects the steel through the normal service life of an indoor cabinet installation and keeps the slide functional in the kitchen and bath humidity ranges it will see. Because the slide rides beneath the drawer box, it stays out of sight when the drawer is open — the finish is there to protect the steel, not to be seen.

The drawer box must be built to the Grass Elite Plus specification for this length: box length matched to the 21 inch nominal, width calculated for the series' side clearance, a bottom recess, and the rear notch and drilling for the Elite Plus front locking devices. Front locking devices are series-specific accessories and do not interchange with locking devices from other Grass lines or other brands.

Who Orders This Slide

Cabinet shops building standard base and bath boxes from 1/2 to 5/8 inch stock will find this the straightforward Elite Plus choice for the 21 inch drawer depth. It handles the load range typical of kitchen and bath drawers — rated 75 lb per pair — without stepping up to the heavier-duty slide classes. Designers specifying concealed hardware for face-frame kitchens appreciate that it works in traditional American construction with the correct rear brackets, and production frameless shops get the same runner without any bracket requirement. It is not the right pick for 3/4 inch drawer sides; those applications need the 19mm Elite Plus version instead.

The Right Concealed Runner for Standard-Depth Cabinetry

Match drawer side thickness, confirm the cabinet construction, add the correct series hardware, and this 21 inch Elite Plus slide gives the drawer a clean concealed look with full access and a quiet, controlled close.
