Grass Dynapro Undermount Slide for Heavy Drawers That Demand More

The 24 inch Grass Dynapro is a heavy-duty, full-extension undermount drawer slide rated 132 lb per pair, designed for wide, deep, or heavily loaded drawers where a standard 90 to 100 lb concealed slide is not enough. It closes silently on its integrated soft-close damper and suits both face-frame and frameless cabinetry.

Key Features

• 132 lb capacity per pair — the heavy-duty Dynapro rating, suited to pots-and-pans drawers, utility pull-outs, and oversized base cabinet drawers that outload standard undermounts.
• Full extension — the entire 24 inch drawer box comes out to the cabinet face, so nothing stays buried at the back.
• Integrated soft-close — a liquid damper catches the drawer near the end of travel and settles it shut without noise or impact.
• Face-frame and frameless compatible — one slide serves both cabinet constructions; face-frame installs require the matching Dynapro rear mounting brackets, sold separately.
• 5 mm side clearance — a tighter clearance than standard side-mount slides, keeping the concealed profile slim under the drawer box.
• Roller-bearing carriage, steel construction, zinc finish — built for years of indoor service under real working loads.

Where This Slide Earns Its Keep

The 132 lb capacity sets this Dynapro apart from the standard 100 lb version and makes it the right choice when drawer contents push the limits of a conventional undermount. Think deep pots-and-pans drawers in a kitchen remodel, utility base cabinets in a workshop, or a double-file-folder pull-out under a home office countertop. Any 24 inch drawer box that carries sustained weight benefits from the extra headroom this rating provides. The full-extension travel means the entire drawer is accessible at once — no reaching past a half-open box to find what is in the back.

Build and Materials

Steel members with a zinc finish handle the demands of indoor cabinetry service reliably. The roller-bearing carriage delivers smooth, even travel under load, and the integrated damper is a liquid-type soft-close, not a spring ramp, so the close is genuinely controlled regardless of how hard the drawer is pushed. The 24-23/32 inch nominal length and 24-7/8 inch minimum installation depth mean the cabinet interior must provide that full depth — measure before ordering. Drawer boxes must be built to the Grass Dynapro specification for this length: correct box width for the 5 mm side clearance, appropriate bottom recess, rear notch, and the drilling required for the Dynapro front locking devices. The slide fits drawer sides from 1/2 inch to 5/8 inch thick; it is not the right choice for 3/4 inch material.

Who This Slide Is For

Cabinet shops and contractors building premium residential or light commercial kitchens will find this slide useful wherever drawer contents are dense or the homeowner expects a drawer that handles heavy use for years. It suits face-frame and frameless construction equally, which simplifies spec decisions when a job mixes both cabinet types. Designers specifying handle-less fronts can pair this slide with Dynapro-compatible locking devices that allow post-install front adjustment — useful on long runs where alignment matters. The heavy-duty rating also makes it a sensible upgrade for renovation work where the original slides were undersized for how the space actually gets used.

The Right Slide for Drawers That Work Hard

When a 24 inch drawer carries more than a standard undermount is built for, the heavy-duty Dynapro closes the gap — full extension, damped close, and 132 lb of capacity, fully concealed beneath the box.
