Side rails for trailers are an essential accessory that adds both functionality and safety to your trailer. Whether you are hauling equipment, materials, or personal belongings, side rails provide an extra layer of security and convenience. In this article, we will explore the different types of side rails available, their benefits, and how to choose the right ones for your trailer.

Types of Side Rails

1. Removable Side Rails

Removable side rails are a popular choice for trailers as they offer versatility. These rails can be easily attached and detached, allowing you to customize your trailer based on your specific needs. They are typically made of lightweight materials such as aluminum or steel, making them easy to handle.

2. Fixed Side Rails

Fixed side rails are permanently attached to the trailer and cannot be removed. These rails provide a higher level of stability and security, as they are designed to withstand heavy loads. They are often made of durable materials like steel or galvanized steel, ensuring longevity and durability.

3. Folding Side Rails

Folding side rails offer the best of both worlds - the convenience of removable rails and the stability of fixed rails. These rails can be folded down when not in use, allowing for easy loading and unloading of cargo. They are commonly used in trailers that require frequent access to the cargo area.

Benefits of Side Rails

1. Enhanced Safety

One of the primary benefits of side rails is the added safety they provide. They act as a barrier, preventing items from falling off the trailer during transport. This is especially important when hauling loose or bulky items that may shift during transit.

2. Increased Load Capacity

Side rails can significantly increase the load capacity of your trailer. By creating a higher sidewall, they allow for taller and bulkier items to be transported without the risk of toppling over. This is particularly useful when transporting construction materials, furniture, or equipment.

3. Secure Attachment Points

Side rails often come with built-in attachment points or slots, making it easier to secure your cargo using straps or bungee cords. These attachment points provide additional stability and prevent items from shifting or sliding during transport.

4. Versatility

With different types of side rails available, you can choose the ones that best suit your specific needs. Whether you require removable rails for occasional use or fixed rails for heavy-duty hauling, there is an option for every trailer owner.

Choosing the Right Side Rails

1. Consider Your Needs

Before purchasing side rails, consider the type of cargo you will be hauling and the frequency of use. If you need the flexibility to remove the rails when not in use, opt for removable or folding side rails. For heavy-duty hauling, fixed side rails are the best choice.

2. Material Selection

The material of the side rails will determine their durability and weight. Aluminum side rails are lightweight and resistant to rust, making them ideal for trailers that require frequent transportation. Steel side rails, on the other hand, offer superior strength and are more suitable for heavy loads.

3. Compatibility

Ensure that the side rails you choose are compatible with your trailer's dimensions and mounting points. Measure the length and height of your trailer bed to determine the appropriate size of side rails. Additionally, check if the mounting brackets or hardware are included with the rails or need to be purchased separately.

4. Budget

Consider your budget when selecting side rails for your trailer. The price of side rails can vary depending on the material, brand, and additional features. It is important to strike a balance between affordability and quality to ensure you get the best value for your money.

Installation and Maintenance

1. Installation Process

The installation process for side rails will vary depending on the type and brand. However, most side rails come with detailed instructions and mounting hardware. It is important to follow the manufacturer's guidelines to ensure proper installation and secure attachment to the trailer.

2. Regular Maintenance

To prolong the lifespan of your side rails, regular maintenance is essential. Clean them regularly to remove dirt, debris, and corrosive substances that may cause damage. Inspect the rails for any signs of wear or loose hardware, and make necessary repairs or replacements as needed.

3. Storage and Transportation

When not in use, store your side rails in a dry and secure location to prevent rust or damage. If you need to transport the side rails, ensure they are properly secured and protected to avoid scratches or dents. Use a cover or padding to prevent any contact with other objects during transportation.


Side rails for trailers are a valuable accessory that enhances both the functionality and safety of your trailer. Whether you choose removable, fixed, or folding side rails, they provide added security, increased load capacity, and versatility. Consider your specific needs, material selection, compatibility, and budget when choosing the right side rails for your trailer. With proper installation and regular maintenance, your side rails will serve you well for years to come.
