Grass Elite 21 inch soft-close undermount drawer slides provide a concealed slide solution that supports 3/4 extension drawer travel, which helps installers deliver smooth access while keeping hardware hidden under the drawer box. The Grass America brand identity signals that these slides belong to the Elite undermount product class, which helps match this set with existing Grass Elite installations on future jobs. The soft-close function is built into the undermount slide system, so drawers can be pushed shut in normal use and still ease into the cabinet without slamming, which protects drawer fronts and helps maintain alignment over time. The 21 inch slide length sets these slides up for drawer designs sized around that nominal depth, which streamlines layout when planning cabinet carcase depths. Being part of the undermount drawer slides category positions this product for projects where side clearance must remain clean for aesthetics or tight reveals.
The 21 inch slide dimension defines the basic drawer depth these Grass America slides are built to support, which helps cabinet builders size drawer boxes and cabinet cases to coordinate with this hardware. Because these slides belong to the undermount drawer slides product class, the running gear sits underneath the drawer, so side clearances can be dedicated to the drawer box and face layout instead of hardware. The 3/4 extension characteristic affects how far the drawer front projects from the face frame or case side during use, which supports planning for handle reach and nearby door clearances in a run of cabinets. As part of the Grass Elite line, these slides align with other Elite undermount components by identity, which can simplify future replacements when matching part numbers across a shop standard.
These Grass Elite undermount drawer slides are categorized under slides, undermount, which positions them for cabinet projects where concealed runners support the design intent. The 21 inch length works with drawer layouts that target that nominal depth, which is common in many cabinet carcasses built around standard base cabinet dimensions. Their 3/4 extension travel defines how far the drawer interior comes forward, which suits applications where front access is important but full extension is not required for the load. The soft-close function contributes to a quieter drawer run, which supports use in kitchens, baths, or shop storage where controlled closing is desirable. The zinc finish named in the description suits interior cabinetry environments, which aligns with typical drawer locations in residential and commercial casework.
The soft-close 3/4 extension action is built into these Grass Elite undermount slides, which lets installers tune reveals and front alignment without adding separate closing devices, simplifying repeatable setups across multiple drawers. Because the slides are undermount, drawer boxes can be sized with straight, unobstructed sides, which supports the use of consistent drawer construction methods across a project. The roller bearing zinc construction provides a defined running surface inside the slide, which supports predictable travel over the full designed extension. The specific manufacturer part number 13139S-03 uniquely identifies this slide set within the Grass America Elite line, which helps shops reorder the same model when duplicating earlier work or maintaining standard hardware specifications. Being classified as undermount drawer slides also signals how these components integrate into cabinet design workflows that standardize on concealed runners.
