3U Fixed 19" Adjustable Depth Universal Server Rack Rails
Mount 19" servers or networking hardware in any standard rack with these universal, adjustable depth 3U rack rails
Product ID: UNIRAILS3U
These 3U server-rack rails let you mount non-rackmount equipment such as desktop servers, networking equipment or KVM switches, into your 19” server rack without sacrificing an additional 1U of rack space, like you would with a traditional shelf. The rack rails are also a great solution for mounting equipment with damaged rails or discontinued OEM equipment such as Dell™, IBM®, HP® or Apple servers that no longer have rack rails available.
This TAA compliant product adheres to the requirements of the US Federal Trade Agreements Act (TAA), allowing government GSA Schedule purchases.
Turn non-rackmount equipment into 3U rackmount hardware
These rack rails add rackmount functionality to your non-rackmount gear, by cradling your equipment in an open frame supported by three sturdy crossbars. You can mount your non-rackmount equipment by mounting the rails to your server rack and placing your equipment on the undercarriage. For equipment that already features mounting holes, the rails also feature multiple mounting patterns to secure your equipment, for an added level of security.
Universal design mounts to almost any 19" server rack
Adhering to the EIA-310 standard for 19” rackmount equipment, these mounting rails are universally compatible with 19” server racks. The depth is adjustable for a variety of rack sizes and configurations. Plus, there is a rear cable management panel that’s removable for additional customization.
To ensure your equipment is secure, these mounting rails feature cold-rolled steel construction. The durable design can support a weight load of up to 100 lb (45 kg).
The UNIRAILS3U is backed by a lifetime StarTech.com warranty with free technical support.

Frequently Asked Questions
Before You Buy
There’s a wide variety of accessories for server racks and today the various options will be explored. Here are the accessories that will be discussed.
- Rack rails and DIN rails
- Casters and leveling feet
- Cable management
- Rack blank panels
- Power Distribution Units (PDUs)
Server rack shelves come in a variety of sizes and styles. We will be covering six different types of server rack shelves.
Server rack shelves have both a U size and depth. The U size describes the height of the shelf in rack units, and one U is equal to 1.74 inches. Shelves might also list a maximum suggested weight and some shelves are available in a vented design for greater airflow.
Fixed shelves have a fixed depth. If you use a server rack with fixed shelves, make sure your rack equipment fits within the mounting depth of the shelf you are purchasing.
Unlike fixed shelves, you can adjust the depth of adjustable shelves. The minimum and maximum mounting depths for adjustable shelves are listed on the product page, under the Technical Specifications tab.
Sliding shelves can be slid in or out of a server rack. These shelves have a lock feature that locks the shelf and prevents it from accidentally falling out or sliding back into the server rack. The minimum and maximum mounting depths for sliding shelves are listed on the product page, under the Technical Specifications tab.
Similar to sliding shelves, drawer shelves feature a sliding storage drawer that is perfect for storing tools, small hardware or other accessories.
Cantilever shelves do not attach to the server rack on all 4 corners; instead, they only attach on one side of the server rack. These shelves generally have lower weight thresholds.
Heavy duty shelves are designed to hold more weight. They are a more durable solution for storing large pieces of equipment that can’t be mounted in a server rack.
Startech.com offers both rack rails and DIN rail kits.
Rack Rails are available in several different U sizes and are often adjustable, allowing you to customize the depth of your server equipment.
DIN Rails are an industry standard for server rack equipment, and StarTech.com offers a DIN Rail kit which fits all standard 19” racks. This kit features adjustable depth and the entire kit occupies 2 U’s of rack space. As with other server rack accessories, check on the product page under the Technical Specifications tab to make sure your equipment will fit within the product’s measurements.
Casters and levelling feet are two of the commonly used methods of mounting a rack on the floor. To determine whether your rack includes casters or levelling feet, on the product page, check the Technical Specifications tab, under the heading What’s in the Box.
Cable management accessories include cable management hooks, panels, and conduits or ducts. More information will be shared on them below.
Cable management hooks are designed to hold cabling to avoid cable knotting or crimping. They are also sometimes referred to as D-Ring hooks and can be found in a variety of sizes.
Cable management ducts or conduits are used to route cables through a covered cable duct. These ducts feature a removable top cover so that you can easily add or remove cables.
A cable management panel consists of several cable management hooks and/or ducts, combining these products for an all-in-one cabling solution.
Rack blanking panels are sometimes called filler panels as they are designed to fill the openings in server racks that are not in use. This provides security as well as physical protection for the equipment in the server rack. Rack blanking panels can be vented or solid and come with or without hinges.
Power distribution units or PDU’s add additional power outlets to your server rack. They are available in U based sizes, such as 1U and some of the more advanced units include power switching, which you can use to power on and off the connected devices over an IP network.
Confirm the number of outlets and the U size you need in your server rack PDU before you make a purchase.

When you install your rack equipment, it’s important to put the heaviest equipment on the bottom of the rack, first. This provides a strong base and is especially important if you are installing a lot of equipment on a tall rack. This also prevents the server rack from becoming top heavy and falling over.
If your equipment is long, heavy, unbalanced or otherwise difficult to handle, ask someone to help you install the equipment so you don’t injure yourself or damage the equipment.
Finally, when you tighten down your screws make sure you don’t strip or damage the screws. This is especially important to be aware of when using electric tools which can generate more torque.
The patch panel will be mounted using cage nuts, so the first step is to install them.
Once installed, the cage nuts can be used to mount our patch panel.
To install your server rack equipment, fasten the mounting screws into the cage nuts. After you tighten your screws, check to make sure your rack equipment is securely installed.
If you have questions about installing equipment into a server rack, contact our technical support team for further assistance.
