Cabinet Hardware & Construction Guide
Full-Extension Drawer Glides
Full-extension glides allow the drawer box to travel completely beyond the cabinet face, making items at the very back easier to see, reach, and organize.
Access the Entire Drawer
What Does Full Extension Mean?
A full-extension glide lets the drawer open far enough for the back of the drawer box to clear the cabinet face. Unlike a partial-extension drawer, which leaves the rear section tucked inside the cabinet, full extension provides practical access to the complete usable depth.
Complete Access
Contents stored at the back remain visible and reachable instead of disappearing beneath the countertop.
Better Organization
Drawer dividers and inserts remain useful across the entire depth of the drawer box.
Smoother Movement
Quality runners support controlled travel and help the drawer remain stable throughout its range.
Cleaner Appearance
Undermount hardware stays concealed beneath the drawer rather than occupying the visible drawer sides.
The Hardware Beneath the Drawer
How Concealed Undermount Glides Work
A pair of runners mounts beneath the drawer box and engages the drawer at the front and rear. When correctly matched to the drawer dimensions and cabinet construction, the system provides full travel while keeping the visible drawer sides clean.
Related—but Not the Same
Full Extension vs. Soft Close
These terms describe two different functions. Full extension describes how far the drawer opens. Soft close describes how the drawer behaves during the final portion of closing. A drawer can include either feature independently, although premium cabinet systems frequently combine both.
Full-Extension Function
- Concerns the drawer's opening travel
- Provides access to the back of the drawer
- Improves use of deep drawer boxes
- Available in different load ratings and configurations
Soft-Close Function
- Concerns the drawer's closing action
- Slows the drawer near the cabinet
- Reduces slamming and abrupt impact
- Requires compatible hardware and proper adjustment
What to Compare
Evaluating Drawer Hardware Before You Buy
Extension Type
Confirm whether the drawer is partial extension, full extension, or an over-travel specialty system.
Mounting Style
Undermount glides remain concealed; side-mount glides are visible alongside the drawer box.
Load Rating
Wide drawers, cookware, pantry storage, and other heavy uses may require higher-capacity hardware.
Drawer Construction
Dovetail joints, finished wood sides, a stable bottom, and accurate sizing contribute to long-term performance.

Common Questions
Full-Extension Drawer Glide FAQ
Do full-extension drawer glides open the entire drawer?
Yes. A correctly installed full-extension system allows the drawer to travel far enough that the back of the drawer box clears the cabinet face and becomes accessible.
Are full-extension and soft-close drawer glides the same thing?
No. Full extension describes opening travel, while soft close controls the final part of the closing motion. Many premium systems include both features.
Are undermount glides better than side-mount glides?
Undermount glides provide a cleaner appearance because the hardware is concealed and are commonly used in premium cabinetry. The best choice still depends on load, drawer design, dimensions, installation, and the hardware specification.
Why does a full-extension drawer need proper adjustment?
Alignment and adjustment help the drawer engage correctly, move smoothly, close evenly, and maintain consistent spacing between surrounding cabinet fronts.
