The metal piece in a file cabinet is commonly known as a file rail, file bar, or file follower. It is a critical component that helps organize folders and documents within a file drawer.

What Does a File Rail Do?

A file rail serves several important functions:

Provides Support and Stability

The file rail sits vertically in the drawer and provides backing and support for folders and files. This helps keep documents neatly organized and standing upright within the drawer. Without a file rail, folders could easily fall over or shift around.

Adjusts to Accommodate Content

File rails are adjustable, allowing you to slide them backwards and forwards to take up more or less space. This adjustable design means the rail can be moved to accommodate different amounts of content.

For example, if a drawer is empty, you can slide the rails all the way to the front. As you add folders and documents over time, you can gradually slide the rails back to make room.

Creates Divisions

Many file cabinets contain multiple file rails per drawer. This allows you to create distinct sections within each drawer.

For instance, you may use one file rail to store monthly financial documents, another for client files, and a third for invoices. The dividers keep each category neatly separated.

Provides Labelling Surface

File rails have a vertical facing that serves as a convenient surface for labels, stickers, or handwritten text indicating what is stored behind. This allows for easy identification of the content in that section of the drawer.

What Are File Rails Made Of?

File rails are most commonly made from sheet metal, typically steel or aluminum. However, rails may also be constructed from sturdy plastic or wood.

Metal is the most popular choice as it provides the greatest durability and strength to withstand frequent sliding and resistance of content pressing against it. Metal also allows for adjustable “spring-loaded” rails that use tension to stay firmly in place wherever they are positioned within the cabinet.

Key Features of File Rails

• Adjustability – The ability to slide backwards and forwards and lock into position. Some may have preset “click stops” while others glide smoothly.
• Ribbing – Vertical ribs that provide rigidity and prevent buckling under pressure.
• Mounting tabs – Along the rear edge, small tabs insert into slots in the cabinet to keep the rail securely aligned.
• Finger slots – Horizontal cuts that make it easy to grip and slide the rail into place.
• Labeling surface – Blank space for adhering labels, stickers, etc. This is sometimes along the top edge or front facing surface.
• Color coding – Rails may be color coordinated to match labeled folders for quick visual organization.

What Are the Standard Sizes?

File rails are designed specifically to fit standard letter/legal size file drawers. The most common dimensions are:

• Height – 10 to 12 inches. Must be slightly shorter than the interior drawer height.
• Width – Usually 1 inch. Provides sufficient surface area for support.
• Length – Variable depending on the front-to-back depth of the filing drawer, typically 18 to 20 inches.

Rails designed for legal/wide drawers are typically a bit taller and wider than letter size. Lateral file cabinets that store files from front to back instead of side-to-side will also require longer rails.

Alternatives to Metal File Rails

While metal rails are the most utilized, there are other options:

• Wooden rails – Made from finished hardwood, these have an attractive look but lack adjustability.
• Plastic rails – More affordable while still offering adjustability. Not quite as sturdy as metal.
• File folders – Using the folders themselves as dividers, without separate rails.
• Hanging folders – Hanging folders often have metal rods/rails built in.
• No rails – Some may opt to forego rails completely and just allow folders to stack freely. This sacrifices organization.

Common Questions About File Cabinet Rails

Here are answers to some of the most frequently asked questions about file rails and their use:

What is the metal piece in file cabinet?

The metal piece in a file cabinet is called the file rail, file bar, or file follower. It serves to divide, support, and organize folders within the drawers.

How do file rails work?

File rails insert vertically into the drawer and can slide backwards and forwards. Tabs on the backside keep them aligned properly. Adjusting the rails allows you to accommodate different amounts of content.

How many file rails are needed?

Most filing drawers are designed to accommodate 2-4 rails per drawer. Rails can divide the drawer into different sections as needed for organization.

Can file cabinets work without rails?

Technically yes, but the folders will not be properly supported and are more likely to fall over. Rails are an important component for optimal filing.

Should rails touch the cabinet bottom?

No, rails are designed to have a small gap between the bottom rail and drawer bottom. This allows smoother sliding.

Can you move file rails once set?

Absolutely. File rails are designed to be adjustable. You can reposition them as needed as folders are added, removed, or reorganized.

Do rails come with new file cabinets?

Not always. Many filing cabinets are sold with rails separate or as optional accessories. However, rails specifically made for that cabinet can usually be purchased.

Can I use homemade file rails?

We don’t recommend it. Homemade rails may not slide smoothly or provide the right fit. Getting rails made specifically for your filing cabinet model is best.

How are file rails attached?

Rails have small mounting tabs that insert into corresponding slots in the cabinet walls. This keeps them aligned properly and in place.

Maintaining and Replacing File Rails

With frequent use, file rails can wear out over time. Here are some tips for keeping them working smoothly:

• Periodically clean debris, dust, and dirt from the rails with a mild cleaner and lint-free cloth. Don’t use anything abrasive.
• If rails become hard to slide, apply a very small amount of silicone spray lubricant to the glide points.
• Ensure mounting tabs are securely inserted into the filing cabinet slots.
• Replace bent or misshapen rails promptly to avoid issues sliding or positioning properly.
• When replacing rails, ensure the new ones match the specific model of your filing cabinet for an exact fit.

Converting to Lateral Filing Systems

Many offices are switching from vertical drawers to lateral filing systems. This changes the orientation of folders from standing upright to laying down side-to-side.

Lateral filing drawer dimensions are wider and shallower than standard vertical drawers. Therefore, longer and lower profile file rails are required.

If converting your cabinet system, be sure to get rails designed specifically for lateral files even if replacing existing rails. The fit, proportions, and adjustability can differ considerably from conventional vertical drawer rails.

Key Takeaways

• File rails are metal divider bars that provide vital organization within filing cabinet drawers.
• They slide backwards and forwards to accommodate different folder volumes.
• Rails create sections, support documents neatly, and give a surface for labels.
• Standard rails are 10-12 inches tall and 1 inch wide, with lengths dependant on drawer depth.
• Metal construction provides the greatest durability for heavy office use.
• Proper rails are crucial to keeping files orderly and accessibility. Damaged or ill-fitting rails should be promptly replaced.

How are File Rails Installed and Utilized?

File rails are a simple yet important element that help keep documents organized in filing cabinets. Here is a closer look at how they easily install, adjust, and work:

Installation

Installing new file rails into a cabinet drawer is quick and simple:

• Identify the small horizontal slots along the inside walls of the drawer. These accept the mounting tabs on the file rails.
• Position the rail vertically in the drawer with the tabs facing the slots.
• Insert the tabs into the corresponding slots to lock the rail securely in place within the drawer.
• For multiple rails per drawer, insert each into its own set of slots while spacing evenly apart.
• Ensure all tabs are fully inserted into their slots so rails remain perpendicular and don’t lean.

Adjusting and Repositioning

The slidable nature of file rails allows repositioning them as needed:

• To move rails, simply grasp the vertical edge and slide gently in either direction. Apply even pressure.
• Rails with preset stops will click audibly into place when positioned over the stops.
• Rails without preset positions can be moved freely to any point within the drawer.
• Start rails in the forward position, then gradually slide back as you add more content over time.
• Avoid positioning rails too far back initially, as this wastes usable space.
• Leave a small buffer gap between the end rail and drawer wall to allow smooth sliding.

Utilization Tips

When putting file rails to use, keep these tips in mind:

• Use labels, stickers, or handwritten text on the outward facing edge to clearly designate each section.
• Use different colored rails or folders to color code the filing system.
• Position the most accessed files towards the front for easy reach.
• Balance heavier folders and those accessed less frequently toward the back.
• Maintain 1-2 inches of space between the tops of folders and cabinet roof for easy removal.
• Keep no more than 3-4 inches of content behind each rail to prevent tipping.
• Avoid overstuffing folders behind rails as this can impede sliding and adjustability.
• Check rails occasionally for dust buildup that could affect sliding. Clean with a soft cloth only.

Following these simple practices helps maintain an orderly, accessible filing system that’s easy to navigate. Routine small adjustments keep everything working optimally.
