This is the right-hand Grass Dynapro 21 inch concealed undermount slide, built for drawer boxes with 5/8 to 3/4 inch sides. It delivers full extension, integrated soft-close, and a 100 lb capacity per pair — sold as a bulk single for production shops stocking by handedness.
The 5/8 to 3/4 inch side range is what separates this version from the standard Dynapro model, which is built around 1/2 to 5/8 inch material. If the shop is building drawer boxes from 3/4 inch Baltic birch, solid maple, or thick-sided plywood, this is the correct version — the spacing, locking devices, and box-width formula are all engineered around that material thickness. Pairing the wrong version with the wrong box thickness causes the front locking devices to seat improperly, so matching version to material is not optional.
The 21 inch length suits standard base cabinet drawers in 24 inch deep frameless cases and is equally at home in face-frame construction with the appropriate Dynapro rear mounting brackets. Dynapro's built-in synchronization also makes this a sound choice for wider drawer openings where shimmy on a non-synchronized slide becomes noticeable.
Steel members with a zinc finish give the Dynapro its durability in everyday residential and light commercial cabinet work. The roller-bearing carriage keeps travel smooth and quiet under load, and because the slide rides entirely beneath the drawer box, the finish is functional rather than decorative — it stays hidden once the drawer is installed. Dynapro front locking devices and rear mounting brackets are series-specific; no other brand's accessories fit this runner, and Dynapro hardware does not transfer to other undermount lines.
This bulk single suits production cabinet shops that stock right-hand and left-hand Dynapro slides by the case and pull from inventory as drawer runs are built. For a shop building boxes from 3/4 inch material at volume, ordering handed singles in bulk is faster and more economical than buying paired sets one drawer at a time. Designers and contractors specifying Dynapro for a premium kitchen build will want to confirm the box construction matches this version's side-thickness range before ordering.
This is the right-hand slide only — one piece per order. Pair it with the matching left-hand 21 inch Dynapro slide to make a complete, working set for one drawer.
Yes. This version is engineered for 5/8 to 3/4 inch drawer sides, making it the correct choice for shops working in 3/4 inch plywood or solid hardwood box construction. The standard Dynapro model designed for 1/2 to 5/8 inch sides is a separate SKU.
Yes. Dynapro suits both face-frame and frameless construction. In face-frame installs, the rear of the slide needs Dynapro-specific rear mounting brackets, which are sold separately. Those brackets are series-specific and do not interchange with other brands.
Dynapro front locking devices are sold separately as series-specific accessories. Confirm the locking device SKU for this version of the slide when placing your order.
Yes. The box must be built to Grass's published specification for this Dynapro version — nominal 21 inch length, the correct box width for the side clearance, the bottom recess, and the rear notch and drilling for the front locking devices. An off-spec box will not seat correctly on the slides.
Match this right-hand slide to its left-hand mate, build the box to Grass's specification for 5/8 to 3/4 inch sides, and the Dynapro delivers full extension and silent soft-close in every drawer on the run.
