This is the right-hand member of Grass's Dynapro undermount system in the 18 inch length, engineered specifically for drawer boxes with 5/8 to 3/4 inch sides. It delivers full extension and integrated soft-close, rated 100 lb per pair, and is sold as a bulk single for production shops stocking by the member.
The 5/8 to 3/4 inch side-thickness range is what sets this Dynapro version apart from the more common 1/2 to 5/8 inch model. Shops building drawer boxes from 3/4 inch solid hardwood or thick plywood, and those dovetailing heavier stock, need this specific version — the 1/2 to 5/8 inch model will not seat correctly on a thicker box. It is equally well suited to face-frame and frameless cabinets, so the same bulk stock covers both construction types in a mixed production run. At 100 lb per pair, the slide handles loaded utensil drawers, deep pantry pull-outs, and file-height rollouts without reservation.
Dynapro runs on a precision roller-bearing carriage inside a zinc-plated steel body. The zinc finish protects the steel through years of indoor service, and because the slide mounts concealed beneath the drawer box, the finish is functional rather than decorative. The integrated soft-close damper is part of the carriage assembly — there is no separate add-on to lose or adjust. Synchronization is also built in at the slide level, so wide-drawer stability comes from the runner itself, not from an accessory rod.
Production cabinet shops are the primary audience for this bulk single. Ordering left-hand and right-hand members separately by the case lets a shop dial in exact quantities without paying for paired retail packaging. Designers and contractors specifying Dynapro for a thick-sided box program — custom furniture drawers, heavy-duty kitchen rollouts, or closet pull-outs built from 3/4 inch material — will find this version the correct fit where the standard 5/8 inch model falls short.
You need one matching left-hand 18 inch Dynapro slide in the 5/8 to 3/4 inch side-thickness version. Two right-hand members will not form a working pair. Order equal quantities of each orientation.
Yes. This version is built for drawer sides from 5/8 inch to 3/4 inch — it is the correct choice for 3/4 inch plywood or solid hardwood boxes. If your sides are 1/2 to 5/8 inch, order the standard Dynapro version instead.
Dynapro front locking devices are series-specific accessories and are not confirmed to ship with this bulk single. Verify which locking devices your Dynapro configuration requires and order them separately to be sure they arrive with the slides.
Yes. Dynapro suits both face-frame and frameless construction. In a face-frame cabinet, the slide's rear end needs the series-specific Dynapro rear mounting brackets — those are sold separately and are not interchangeable with brackets from other slide brands or series.
Per pair, as undermount slide ratings are stated throughout this segment. One right-hand and one left-hand slide together carry 100 lb.
Match the 5/8 to 3/4 inch side-thickness version to your box stock, pair right-hand with left-hand members, add the Dynapro locking devices and any brackets your cabinet construction requires, and every drawer in the run installs on the same proven runner.
