Grass DynaPro undermount drawer slides bring soft-close, full-extension performance to drawers using a concealed undermount layout. Synchronization for excellent running performance keeps both sides of the slide moving together, so drawers track smoothly along their full travel, which helps finished drawers feel solid in everyday use. The fully enclosed liquid damper soft glides drawers to a stop, controlling closing speed so drawers shut gently instead of slamming. This 21 inch slide uses roller bearing Zinc construction, which supports the guided movement of the drawer while keeping the working hardware protected beneath the drawer box. The design works for both 16 mm, or 5/8 inch, and 19 mm, or 3/4 inch, drawer material, so builders can use common side thicknesses across a project without changing the slide family. Self-latching front locking devices provide maximum connection of drawer slide, securing the drawer box to the slide for confident operation.
This Grass America DynaPro 21 inch undermount drawer slide uses a full extension design, so the slide geometry lets the drawer box travel entirely out of the cabinet, which helps access contents at the back of deeper drawers. The 1D, 2D, and 3D adjustment - height, side, and depth - is built into the system, providing separate ways to shift drawer position vertically, laterally, and in or out. That combination supports precise fitting of drawer fronts to face frames or casework, because each direction can be tuned independently. Support for both 16 mm and 19 mm drawer material means side-clearance planning can follow Grass DynaPro standards across different box thicknesses while using the same undermount runner style. The self-latching front locking devices engage the drawer to the slide, forming the primary working connection at the front of the drawer for daily opening and closing.
The manufacturer part F130135020299 identifies a 21 inch LEFT bulk DynaPro undermount slide, aligning with drawer depths designed around that runner length. As an undermount drawer slide, it is positioned beneath the drawer box, which leaves the drawer sides unobstructed for 16 mm, or 5/8 inch, and 19 mm, or 3/4 inch, material. That flexibility supports applications ranging from slimmer European-style drawer boxes in 16 mm stock to more robust 19 mm constructions using the same Grass DynaPro undermount drawer slides. The full extension format is useful in cabinets where complete access to stored items is important, because the geometry lets the drawer clear the cabinet front fully during travel. Synchronization for excellent running performance keeps motion even across both sides, so wider drawers within the 21 inch depth can move in and out more uniformly along the slide length.
The fully enclosed liquid damper that soft glides drawers to a stop is central to DynaPro soft-close full extension slides, because the damper absorbs energy as the drawer nears the cabinet, then finishes the close smoothly. That action supports quieter casework in use and reduces shock to drawer contents. 1D, 2D, and 3D adjustment - height, side, and depth - lets installers respond to variations in cabinet squareness or drawer box size by shifting the front vertically, laterally, or in projection, so reveals line up across a bank. Self-latching front locking devices provide maximum connection of drawer slide at the front, creating a firm mechanical link that carries opening and closing forces into the undermount runners. Suitable for drawers up to 48 inch wide with no additional synchronization hardware means standard drawers in that width range can rely on the integrated synchronization for smooth movement.
The F130135020299 part is a Grass DynaPro 21 inch soft-close full extension undermount drawer slide, so it supports concealed mounting beneath the drawer with complete extension.
This DynaPro undermount slide is designed for 16 mm, or 5/8 inch, and 19 mm, or 3/4 inch, drawer material, so it suits common drawer box constructions using those side thicknesses.
The Grass DynaPro undermount drawer slide uses a fully enclosed liquid damper that soft glides drawers to a stop, so closing energy is controlled and drawers settle gently against the cabinet.
This soft-close undermount drawer slide offers 1D, 2D, and 3D adjustment - height, side, and depth - allowing installers to align drawer fronts precisely within surrounding cabinet faces.
The Grass DynaPro undermount drawer slide is suitable for drawers up to 48 inch wide with no additional synchronization hardware, supporting broad drawers within that width range.
Self-latching front locking devices provide maximum connection of drawer slide, so the drawer box stays securely engaged with the undermount runners during use.
The Grass DynaPro undermount drawer slides described here pair a 21 inch full-extension runner with soft-close damping, 1D, 2D, and 3D adjustment, and support for both 16 mm and 19 mm drawer material. For projects needing concealed hardware, smooth synchronized travel, and a self-latching connection between drawer and slide, this Grass America DynaPro option aligns with those requirements. Choosing the F130135020299 part ties drawer depth, side thickness, and soft-close performance together in a single undermount slide family for consistent results across cabinets.
