Tekmart Africa offers a wide variety of Dell rack rail kits for mounting various types of equipment including servers, storage arrays, KMM/KVM consoles, routers, and switches.
Equipment racks can come as two post racks or four post racks with either square holes or round holes. Rail kits will need to not only work with the specific system but also either be universal or created specifically for one of these rack types.
In order to make sure you select the correct rail kit for your device, you will need the model number of your device / system and the type of rack you have.
