Grass Dynapro Undermount Drawer Slide for Thick-Sided Drawer Boxes

This 12 inch Grass Dynapro undermount slide is built for drawer boxes with 5/8 to 3/4 inch sides — the version that fits shops working in thicker hardwood or 3/4 inch plywood without a side-thickness compromise. Fully concealed beneath the box, it runs on integrated soft-close and delivers full extension at a 100 lb per pair capacity.

Key Features

• 5/8 to 3/4 inch drawer side compatibility — designed specifically for thicker drawer box material, including 3/4 inch hardwood and plywood sides.
• Full-extension travel — the entire drawer box comes out to the cabinet face, giving complete access to the interior.
• Integrated soft-close — a built-in damper catches the drawer near the end of travel and settles it shut without slamming.
• 100 lb capacity per pair — handles loaded kitchen, bath, and utility drawers at this length.
• Roller-bearing steel construction with zinc finish — smooth, quiet travel through years of indoor service.
• Face-frame and frameless compatible — suits both common cabinet constructions with the correct mounting hardware.

Built for the 12 Inch Thick-Side Drawer

The 12 inch length covers small base cabinet drawers, spice pull-outs, and compact utility drawers where a shorter box is the right fit. What sets this model apart within the Dynapro line is the drawer side thickness range: 5/8 to 3/4 inch. Shops building boxes from 3/4 inch solid hardwood or 3/4 inch cabinet-grade plywood can install this slide without modifying the box material or ripping sides to a thinner dimension. The slide's spacing, locking-device geometry, and box-width formula are all engineered around this thickness class. Minimum installation depth is 12-7/8 inches, so confirm the cabinet's interior depth accommodates the slide before ordering.

Steel Construction, Zinc Finish, Roller Carriage

Dynapro runs on a roller-bearing carriage inside steel members finished in zinc — a durable combination for drawer hardware that lives hidden beneath the box and handles daily cycling. The 6mm side clearance is tighter than the standard 1/2 inch clearance of most side-mount slides, so the drawer box width must be calculated from the Grass specification for this series, not from a generic formula. The zinc finish is functional: because the slide is concealed when the drawer is open, appearance is secondary to protection and smooth operation over thousands of cycles.

Who This Slide Suits

This model is the right choice when 3/4 inch material is already in the workflow and switching to thinner drawer sides is not practical. Custom cabinet shops building solid wood boxes, production shops running 3/4 inch plywood drawer stock, and remodelers matching existing thick-side construction all benefit from specifying the correct side-thickness version from the start. It also suits face-frame and frameless cabinets alike. In face-frame installs, Dynapro-specific rear mounting brackets are required at the back of the slide — these are sold separately and are not interchangeable with rear brackets from other undermount lines. Front locking devices are also Dynapro-specific; confirm whether they are included with this SKU or need to be ordered separately before building the job list.
