Drawer slides are humble, but they’re the cabinet gods in the background. A heavy-duty drawer slide offers smooth gliding, quiet function, and durable support for kitchen knives, office supplies, and anything in between. Undermount and bottom mount drawer slides are two of the most common styles of drawer hardware, each with their own features of installation, performance, and uses.
In this lesson, we’re comparing undermount vs bottom mount drawer slides on the basis of installation, weight capacity, looks, and usability appropriateness. If you’re a furniture maker, cabinet fitter, or a purchasing expert looking for reliable hardware, you need to understand the difference between these two systems to be successful in a project.
What Are Undermount Drawer Slides?
Undermount drawer slides are mounted under the drawer box and completely hidden when the drawer is open. This creates a sleek, high-end look prevalent in modern kitchens and custom furniture applications. Generally offered with full extension and soft-close capability, undermount slides offer smooth, quiet gliding action.
Key Features:
- Hidden mechanism for premium aesthetics.
- Soft-close for quiet, controlled operation.
- Full extension allows complete access to drawer contents.
- High load capacity, often exceeding 75 lbs.
- Requires precise installation, often using jigs or templates.
- Ideal for custom cabinetry and high-end furniture.
What Are Bottom Mount Drawer Slides?
Bottom mount drawer slides, or epoxy slides, are attached to the bottom of the drawer and are exposed partially when the drawer is in the open position. They are found more often in budget-friendly cabinets, office equipment, and rental units due to ease of installation and low cost.
Key Features:
- Partially visible mechanism during drawer operation.
- Generally offers partial extension only.
- Lower load capacity, suitable for light to medium contents.
- Easier to install, forgiving of drawer dimensions.
- More affordable than undermount systems.
- Best for economical or utility-based projects.

When Should You Choose Undermount Drawer Slides?
Choose undermount slides if:
- You’re building or upgrading modern, premium-quality cabinets.
- Aesthetics and seamless drawer appearance matter.
- You need smooth, full-extension access to the contents.
- Drawers will bear heavy loads (e.g., cookware, tools).
- You want quiet, soft-close functionality for daily use.
When Should You Choose Bottom Mount Drawer Slides?
Choose bottom mount slides if:
- You’re working with a tight budget.
- The drawer holds light to moderate items.
- You’re installing furniture in rental units or offices.
- You want a quick and easy installation process.
- You don’t need full extension or a high-end appearance.
Installation Tips & Common Mistakes
For Undermount Slides:
- Measure drawer width and clearance precisely (usually 3/8″ each side).
- Use manufacturer templates for proper alignment.
- Ensure slides are level and parallel to avoid jamming.
- Install brackets securely; poor anchoring affects performance.
For Bottom Mount Slides:
- Allow 1/2″ side clearance for proper fitting.
- Use durable screws to prevent loosening over time.
- Double-check that slides are evenly installed to avoid drawer tilt.
