There are a variety of full extension, bottom mount drawer slides available. Each of them has a different design which provides a unique set of features and benefits. Here are the main types:
Ball-bearing drawer slides
The ball bearing drawer slides are very popular. They use steel balls that roll in a track to support the drawer. The tracks are mounted on the bottom of the drawer and the cabinet. They are smooth, quiet, and able to support a lot of weight. They come in single or double rail systems. The single rail system has one track with bearings. The double rail has two tracks with bearings. The ball bearing slides are easy to install and very adjustable. They are a good choice for any room in the house.
Roller drawer slides
These are also bottom-mounted. They have rollers instead of ball bearings. The rollers are in a track. The roller slides are very simple. They have fewer parts than ball-bearing slides. They are very quiet and very smooth. They are best for lighter drawers. These slides are less expensive than ball-bearing slides. They are very suitable for budget-friendly projects.
Soft-close drawer slides
These slides are popular for kitchen and bathroom drawers. They have ball bearings or rollers. But they also have a unique soft-close mechanism. The mechanism allows the drawer to close quietly and gently. It uses hydraulic or pneumatic force. The soft-close feature makes the drawers feel more luxurious. It adds to the convenience and privacy.
Heavy-duty drawer slides
These slides are specifically for heavy drawers. They can carry a lot of weight. For example, they can support toolboxes or large kitchenware. The slides come with steel ball bearings or massive rollers. They have multiple rows of balls or rollers. This increases their weight capacity. They are very durable and stable. They also provide full extension. Therefore, users can easily access the drawer contents.
Soft-close undermount drawer slides
These slides are for modern and high-end cabinets. They are mounted inside the drawer. They have a soft close and full extension feature. Their unique mechanism allows the drawer to close quietly and gently. Like the other soft-close slides, they use hydraulic or pneumatic force. They are very smooth and silent. They give a clean and seamless look to the cabinet.
Full Extension:
The full extension is a key feature of bottom mount drawer slides. This allows the drawer to be pulled out completely, providing easy access to the entire contents. This is especially useful for deep or heavy-loaded drawers, as it eliminates the need to reach into the back. Full extension also maximizes storage space by allowing items to be stored and retrieved without hindrance.
Ball Bearing Glide System:
Many bottom mount drawer slides employ a ball bearing glide system. This enables smooth, quiet, and effortless drawer movement, even with heavy loads. The ball bearing system reduces friction and wear over time, ensuring durability and consistent performance.
Weight Capacity:
These drawer slides are designed to support a wide range of weights, making them versatile for different applications. Depending on the model, weight capacity can vary. However, they are generally capable of supporting drawers loaded with kitchenware, bedroom essentials, or office supplies.
Easy Installation:
These slides are designed for easy installation. They are bottom-mounted, meaning they attach to the bottom of the drawer rather than the sides. This simplifies the process of aligning and installing the slides, making them suitable for DIY projects or professional installations.
Adjustability:
Another important feature is adjustability. Some models allow lateral and front-to-back adjustments. This ensures precise alignment of the drawer with the cabinet opening, creating a seamless and professional look. Adjustability also compensates for any slight variations in the installation area, ensuring smooth drawer operation.
Durable Construction:
The bottom mount drawer slides are constructed with durability in mind. They are typically made of high-quality steel resistant to bending, deformation, and wear. Some models may feature zinc or chrome plating to enhance longevity and smoothness. This durability ensures that the drawers operate reliably for many years.
Easy Maintenance:
Maintaining these slides is a straightforward process. They are designed to withstand dust and debris accumulation. Periodically lubricating the ball bearing glide system ensures smooth operation and prevents friction. The durable construction also means that cleaning the slides with a damp cloth is usually sufficient to keep them in good condition.

When choosing the right drawer slide for a specific application, considering certain factors is important. This will ensure that the selected slide will support the weight of the drawer and the contents, fit into the desired space, and provide the required travel distance. Below are some of the things to consider when choosing the right drawer slide:
Load capacity
It is important to consider the contents that will be stored in the drawer and their weight. For light-weight items, light-duty drawer slides will suffice. These are usually rated between 35 and 50 pounds. For medium-duty, they can handle weights between 50 and 100 pounds. And for heavy-duty, they can handle weights of up to 200 pounds.
Drawer width
Drawer slides come in different lengths to accommodate various drawer widths. Measuring the width of the drawer opening and selecting a slide that fits is important.
Travel distance
Full extension drawer slides provide easy access to the contents of the drawer, as they allow the drawer to be pulled out completely. This is particularly useful for deep drawers or those storing bulky items.
Material and finish
Bottom mount drawer slides can be made from steel, plastic or aluminum. Steel slides are more durable and provide better load capacity, while plastic and aluminum are lighter and resistant to rust. It is also important to consider the finish of the slide, which can affect its appearance and performance. Options include galvanized, powder-coated and chrome-plated finishes.
Installation method
It is important to consider the installation method, as some require professional installation while others can be installed as DIY projects. Ball bearing drawer slides offer smooth and quiet operation, while nylon roller slides are more economical and easier to install.
Adjustability
Some drawer slides offer adjustable features that allow users to customize the fit and operation of the drawers. This is useful in cases where the drawer opening is not uniform or when the user wants to change the friction or the clearance of the drawer.
Q: What is the difference between a ball bearing and a roller bearing slide?
A: Ball bearing slides use steel balls between the two metal channels to reduce friction, making them smooth and quiet. Roller bearing slides have nylon rollers that run in grooves, making them less expensive but not as smooth or long-lasting as ball bearings.
Q: How much weight can a bottom mount drawer slide hold?
A: The capacity varies by model. Many ball bearing slides can support 75 to 100 pounds per pair. Heavy-duty options can hold over 150 pounds. It's important to check the specifications for weight capacity.
Q: Are soft-close bottom mount drawer slides worth it?
A: Yes, soft-close slides are worth it. They prevent drawers from slamming shut, which protects the drawer and the contents. They also make the closing motion feel more luxurious and high-end.
Q: Can bottom mount slides be installed on existing drawers?
A: It is possible, but it will depend on the current configuration of the drawers and the space available. A bottom mount slide may take up more or less room than the original slide. If the current bottom mount is not compatible with the existing hardware, it may need to be replaced. It is best to consult with a professional to determine the feasibility of the project.
Q: How to measure for a bottom mount drawer slide?
A: Measure the length of the existing slide from the back mounting point to the front. Then, look at the load rating to determine what kind of slide will work best. Finally, subtract one inch to determine the new slide length. This will ensure that the new slide will fit inside the drawer without any issues.
