Cabinet Hardware 101: A Guide to Drawer Slides

When it comes to cabinet functionality, few components are as crucial as drawer slides. While they might go unnoticed when everything is working smoothly, the moment a drawer sticks, sags, or slams shut, you know something’s wrong. Understanding drawer slides—and choosing the right ones—can make a huge difference in the performance and longevity of your cabinetry.

In this installment of our Cabinet Hardware 101 series, we’ll break down the types, features, and key considerations when selecting drawer slides for your next project.

What Are Drawer Slides?

Drawer slides (also called drawer runners) are the mechanisms that allow drawers to open and close. They consist of a set of metal rails attached to the drawer and the cabinet frame. High-quality slides ensure smooth, quiet operation and prevent drawers from tilting, sticking, or falling out entirely.

Types of Drawer Slides

1. Side-Mount Slides

• Mounted on the sides of the drawer and cabinet opening.
  
  
• Visible when the drawer is open.
  
  
• Pros: Easy to install, high weight capacity.
  
  
• Best for: Utility cabinets, garages, or anywhere function matters more than aesthetics.
  
  

2. Under-Mount Slides

• Mounted underneath the drawer, hidden from view.
  
  
• Sleek, modern appearance.
  
  
• Pros: Full extension, soft-close options, high-end look.
  
  
• Best for: Kitchen and bathroom cabinetry, premium furniture.
  
  

3. Center-Mount Slides

• Single slide mounted under the center of the drawer.
  
  
• Limited in weight capacity.
  
  
• Pros: Minimal visibility, simple installation.
  
  
• Best for: Light-duty drawers in bedroom or office furniture.
  
  

4. European Slides (Roller Slides)

• Economical and widely used.
  
  
• Usually side-mounted with a roller mechanism.
  
  
• Best for: Budget-friendly furniture or entry-level cabinetry.
  
  

Extension Types

• 3/4 Extension: Drawer opens partially; good for shallow drawers.
  
  
• Full Extension: Drawer opens completely, allowing full access.
  
  
• Overtravel: Extends past the cabinet face; ideal for deep drawers.
  
  

Features to Consider

• Soft-Close: Slows the drawer as it closes for a gentle, quiet shut.
  
  
• Self-Close: Mechanism pulls the drawer shut once it’s near closed.
  
  
• Push-to-Open: No handles needed—great for minimalist designs.
  
  
• Weight Rating: Choose based on drawer contents (standard: 75-100 lbs; heavy-duty: 150+ lbs).
  
  

Drawer Slide Installation Tips

• Ensure cabinet and drawer dimensions are accurate.
  
  
• Use a jig or template for consistent mounting.
  
  
• Always check for level alignment—both vertically and horizontally.
  
  
• For under-mount slides, use drawers with notched backs and specific side clearance.
  
  

Choosing the Right Slides for Your Project

Think about how the drawer will be used:

• Kitchen utensils? Go with full-extension, soft-close under-mounts.
  
  
• Tool storage? Heavy-duty side-mounts will do the trick.
  
  
• Light use in a nightstand? Center-mount or roller slides could be enough.
  
  

Drawer slides may be behind the scenes, but they play a starring role in the everyday function of your cabinetry. Whether you're a seasoned woodworker or a DIY enthusiast, investing in the right slides can elevate the quality, comfort, and value of your projects.
