This Grass Dynapro left-hand cabinet member is an 18-inch soft-close, full-extension undermount drawer slide designed for drawer sides ranging from 1/2 inch to 5/8 inch thick. It suits both face-frame and frameless cabinet construction, carrying up to 100 lb per pair on roller bearings with an integrated soft-close damper.
An 18-inch slide length is well matched to standard base cabinet drawers — deep enough to carry a full drawer box but compact enough for shallower utility drawers in bath vanities and small built-ins. Full extension means the rear of the box clears the cabinet opening completely, which matters in a pots-and-pans drawer, a file drawer, or any pull-out where the back contents need to be reachable without pulling the whole box out by feel. The soft-close action benefits any shared space — kitchens, bathrooms, and offices where quiet operation is expected. Because this slide accepts both face-frame and frameless cabinet construction, a shop running mixed order types can carry one SKU rather than two.
The Dynapro is a roller-bearing undermount slide — precision nylon rollers support the drawer box from beneath, keeping the slide concealed below the box where nothing shows when the drawer is open. The steel body in a zinc finish resists the humidity and cleaning products that shorten the life of uncoated slides in kitchen and bath environments. Drawer sides between 1/2 inch and 5/8 inch (12mm to 16mm) fit this version; building the box to the Dynapro's published specification — including the correct box width formula, rear notch, and locking-device drilling — is required for proper seating and adjustment. This is the left-hand cabinet member: order the matching right-hand member and both drawer members to build a complete, working drawer pair.
Cabinet shops running Dynapro as their standard undermount specification will use this left-hand member to fill out drawer sets or replace a single handed component without ordering pairs they don't need. Designers specifying full-extension soft-close slides for kitchen or bath packages find the Dynapro's load rating and dual cabinet-type compatibility a practical fit for mixed project scopes. Contractors sourcing for a specific face-frame install — where frameless slides can be made to work with rear brackets but the right slide simplifies the job — will find this 18-inch left-hand member a direct answer. In face-frame installations, rear mounting brackets are required to support the back end of the slide; those brackets are Dynapro-specific and sold separately.
Yes. This is the left-hand cabinet member only. A complete drawer requires one left-hand and one right-hand cabinet member, plus both drawer members. Order the matching right-hand member separately to complete the pair.
No. This version is designed for drawer sides from 1/2 inch to 5/8 inch. For 3/4 inch (19mm) sides, look for the Dynapro model specified for that thickness — using the wrong version will prevent the locking devices from seating correctly.
In a frameless cabinet the slide mounts directly to the flat side panel — no rear brackets needed. In a face-frame cabinet, the cabinet side is set back from the frame, so Dynapro-specific rear mounting brackets are required to support the back of the slide. Those brackets are sold separately.
Yes. The Dynapro program supports Grass Tipmatic Soft-close, a combined push-to-open and soft-close system. That set is a separate order; it works with all Dynapro 2D and 3D slides in this length range. Keep in mind the synchronization bar for wide drawers is also a separate item and is not included with the Tipmatic set.
Full extension means the drawer member travels approximately the full slide length, bringing the entire drawer box out to the cabinet opening. The full contents of an 18-inch drawer are accessible without reaching inside the cabinet — a meaningful difference from 3/4-extension slides, which leave the rear few inches inside the cabinet box.
Pair this left-hand Dynapro cabinet member with its right-hand counterpart and the drawer members, build the box to spec, and the result is a full-extension, soft-close undermount drawer that works in either cabinet construction — built for daily use at a 100 lb load rating.
