This is the left-hand narrow front locking device for Grass Dynapro undermount slides with 1D adjustment, color-coded green for fast, error-free identification on the shop floor or at the jobsite. It snaps the drawer front to the slide at the drawer box front and provides up to 3.5mm of height adjustment to true the front in place after hanging.
Front locking devices are what fasten the drawer front to the undermount slide after the box is built and the slides are installed. On a Dynapro 1D installation, this left-hand narrow device seats under the front of the drawer box and locks the front panel in position. The 3.5mm of height adjustment lets you nudge the front up or down after hanging, which matters on multi-drawer columns where uniform reveals are the goal. The narrow profile suits drawer front widths and box configurations where the standard-width Dynapro device would crowd the front fixing area.
The device body is plastic, which keeps weight minimal and avoids marring the underside of the drawer front during adjustment. The green color serves a practical purpose beyond aesthetics: in a shop that runs multiple Dynapro adjustment variants side by side, green is the visual cue that separates this 1D narrow device from other locking device types in the same bin or kit. Because Dynapro front locking devices are engineered to the Dynapro slide geometry, this part does not fit MOVENTO, TANDEM, or any other undermount system — and no other brand's locking device fits Dynapro. Order from within the Dynapro accessory family to keep the system complete.
Cabinet shops running Grass Dynapro 1D slides are the primary audience. If a locking device is lost, damaged, or missing from a project kit, this replacement gets the installation back on track without pulling a whole slide set. Designers specifying narrow drawer fronts on Dynapro-equipped cabinetry should confirm the narrow device is called out in the hardware schedule rather than the standard-width version. This is a left-hand device only; a working drawer requires one left-hand and one right-hand device, ordered separately.
The narrow designation refers to the device's profile width at the drawer front interface. If your drawer fronts are narrower than the standard Dynapro front fixing footprint allows, or if the Grass specification for your drawer configuration calls for the narrow device, this is the correct part. When in doubt, cross-reference the Dynapro installation guide for your specific front width.
The green color is a manufacturing identification code, not a performance tier. This device provides 3.5mm of height adjustment regardless of color. Different color codes in the Dynapro locking device range can indicate different adjustment types or device variants, so always verify the part matches your slide series before ordering.
This is a 1D locking device, meaning it provides height adjustment only. Dynapro 3D and 4D slides use their own matching locking devices that support additional adjustment directions. Using a 1D device on a 3D or 4D slide installation will limit your adjustment capability and may not seat correctly — match the locking device to the slide's adjustment specification.
This listing is for the left-hand device only. A complete drawer front installation requires both a left-hand and a right-hand locking device. Order the matching right-hand narrow Dynapro 1D device separately to finish the drawer.
A missing or mismatched locking device stalls a drawer installation at the last step. Having the correct left-hand narrow Dynapro 1D device on hand — identified at a glance by its green color — means the drawer front goes on straight, adjusts cleanly, and the job moves forward.
