2. What Are Side Mount Drawer Slides?
Slides attached to the side of drawers or cabinet boxes are side-mount drawer slides. Their simplicity and affordability make them a common choice.
These can either be ball-bearing or roller-based and are easy to install and replace.

Advantages of Side Mount Slides:
Durability: An ideal slide for drawers due to its durability. These slides can support substantial weight.
Variety: Whatever material, length, or load ratings required, these are available in a wide range of varieties.
Cost-Effective: Having a tight budget? These affordable drawer slides are cheaper than undermount options.
Limitations:
Visible Hardware: When you want an appealing look, side mount slides won’t fit in this case. These are visible when you open the drawer.
No Soft-Close Technology: Unlike undermount slides, side mount makes a little creaky noise and is heavier to pull in and out.
Misalignment: Without proper installation, these side mount slides displace from their position.
3. Key Factors to Choose the Right One
Now that you’ve understood the basics of undermount and side mount slides, let’s break down the key factors to help you pick the right fit for your needs:
● Aesthetics
When appearance plays a crucial role, undermount slides are the best choice. Their hidden position improves the drawer's visual appeal, also allowing smooth opening and closing. Unlike visible metal hardware on the drawers' sides, these keep the design clean and minimalistic. Therefore, it’s ideal for contemporary kitchen cabinetry, custom furniture, and luxury bathroom vanities.
However, sidemount slides are functional but visible when the cabinetry door opens, which affects the aesthetics of residential interiors. For homeowners looking for an appealing accessory, undermount drawer slides should be your go-to choice.
● Functionality
Areas with frequent drawer or cabinet use must have smooth motion slides. That’s where undermount slides become popular. These are equipped with soft-close technology to glide the drawer with less effort. Thus, they’re a valuable option for kids' rooms, workspaces, or the kitchen, so there’s no noise disturbance.
On the other hand, side-mount slides might create little noise and require effort to close properly. So, if you value a quiet and smooth operation, opt for undermount drawer slides.
● Installation & Maintenance
Installing undermount drawer slides requires precise dimensions to fit the drawer. For professional installations, you should check if these slides fit your drawer before buying. They require less maintenance due to their hidden position, as they’re less likely to be damaged through everyday use—though adjustments or replacements are difficult.
Side-mount slides are a versatile option for standard drawers, suitable for quick upgrades or cost-effective installations. Their simple structure speeds up efficiency. However, they need regular cleaning to prevent dust accumulation in the components and extend their lifetime, and maintenance can be done in commercial settings without removing the entire drawer.
● Weight Rating & Space
For heavier weights, side mount slides (especially full extension, ball-bearing versions) offer more support than other alternatives thanks to their robust design. Undermount slides are better for lighter items like cutlery or documents, though some models now offer more strength for utility spaces or cabinets storing larger items.
In terms of space, undermount drawer slides positioned under the drawer allow you to lower the drawer height. Side mount slides, on the other hand, are a suitable choice for narrow drawer widths in confined cabinets.
Expert Tip
When renovating your kitchen or custom furniture, undermount drawer slides might be the right accessory, offering a classy look and smooth finish. However, go for side mount slides if you're tight on budget—they fit best for rental properties and load-bearing drawers. In some situations, using both can be the best strategy: side mount slides in utility or storage areas and undermount slides in visible, high-touch locations.
