Our universal rails and are easy to install, easy to use, and serve as a replacement for many OEM server rails, including those made by Dell, HP, IBM, Supermicro, and more. 

Before you purchase the rack rails, you also need to determine your server’s mounting specifications.

If you’re looking for an excellent alternative to OEM rails, then you should consider using our universal rack rails or 2 post universal rack rails that best fits your setup.

Universal Rails vs OEM Rails

Between universal rails and OEM rails, there are different benefits of selecting universal rails for your servers. To begin with, servers can last longer than 10 years, but the accessories associated with them may not. However, universal rails will always function the same as long as industry standard dimensions are consistent. Additionally, some brands don’t provide server rack rails after the initial purchase.

Secondly, universal rails can be cheaper than OEM rails depending on your server model. If you need to mount a variety of servers, then it may be easier and less costly to purchase one type of rack rail for all of them.

Lastly, your OEM rails can’t be utilized when it’s time to update server equipment. Instead, you could save money more by using universal rails.

Our universal rack mount rails are a fixed rail type and provide a flexible solution for incompatible rack rails within 19” server racks. However, these universal rails are only designed for 4 post racks. If you have a 2 post rack, then you should consider using our 2 post universal rails

Measuring The Depth of Your Equipment

The 2 post universal rail has a mounting depth range of 10 – 31.75″ (254 – 806 mm). Before selecting your 2 post rack rails, it’s important to measure the depth of your equipment. This will ensure that the rails you select are compatible with your equipment. 

You need to measure the depth from the front of the equipment to the back, including any protruding cables or connectors. Once you have this measurement, you can select rails that are the appropriate depth and will securely hold your equipment in place. 

Mounting 2 Post Rack Rails

Depending on your setup, the rails can be mounted in both center and flush settings, which makes them easy to deploy in a variety of settings.

FAQs: Server Rack Rails

What U height should my rail be?

If you are buying rails which are designed for a specific server, they are already sized to be the optimal U height for that piece of equipment.

Universal rails, on the other hand, will be able to hold your server as long as it is under the weight capacity. For instance a 1U universal rail can hold a 2U server as long as that server is less than 45 lbs. Best practice is to purchase a rail that takes up the same number of rack units as your server.

What’s the difference between mounting depth and equipment depth? 

Mounting depth refers to what sized rack the rail will fit inside. For example, a Cobra 90 Rail with a mounting depth range of 20” – 30” will fit inside of racks with 20” – 30” of space between the connection points on the uprights.

Equipment depth, on the other hand, describes what length equipment must be to fit on the rail. A Universal Rail can mount equipment up to 35” deep. This is mostly relevant to rails that are compatible with multiple servers.  

Is all the hardware included? 

Most of our rails work with square, round and threaded hole racks. Because of this, we include all the hardware that is needed to mount the rails in any type of rack. All you’ll need is a phillips head screwdriver, unless you’re using our tool-less rails in which case you don’t need any tools at all.
