The StarTech.com 1U 19 inch Server Rack Rails (UNIRAILS1UB) are a universal, adjustable-depth rack mount rail kit designed for standard 19-inch four-post server racks.

Constructed from heavy-duty cold-rolled steel with a durable black powder-coated finish, these rails offer robust support for network equipment, servers, and UPS units. The adjustable depth range from 24 to 36 inches ensures compatibility with a wide variety of enclosures, while the tool-less slide design allows for quick installation and easy access to mounted hardware. Each rail set includes all necessary mounting hardware and supports equipment weighing up to 100 pounds (45 kg) per pair. The rails feature a smooth sliding mechanism with lock-in and lock-out positions for secure service access. This kit is compatible with major server brands including HPE ProLiant, Dell PowerEdge, and generic rack-mount devices, providing a reliable and versatile mounting solution for data centers, server rooms, and enterprise IT environments. The precision-formed construction ensures consistent alignment and stable equipment placement over extended periods. With its universal fit and straightforward installation process, this rail kit is an economical choice for consolidating and organizing rack-based equipment. The product’s focus on structural integrity and ease of use makes it suitable for both professional IT deployments and home lab setups. The absence of moving parts in the rail body reduces long-term wear, while the corrosion-resistant coating prolongs service life. This kit is a practical accessory for optimizing rack space and maintaining efficient cable management. Its affordability is reflected in the high value provided, offering a cost-effective alternative to proprietary rail systems without sacrificing functionality or durability. The rails are designed with a standard 1U height and can be installed in both square-hole and threaded-hole racks using the included cage nuts or screws. The depth adjustment mechanism is tool-free, allowing rapid repositioning when migrating equipment between different rack depths. Each rail pair ships with clear instructions and all necessary fasteners, minimizing setup time. The load capacity of 100 pounds per pair is conservative for typical server and UPS applications, ensuring a safety margin for heavier devices. The sliding mechanism includes a front-locking feature to prevent accidental dislodging during maintenance. The rails support flush-mount and center-mount configurations, adapting to various chassis layouts. The black powder coat finish matches standard rack aesthetics and resists scratches and chipping. For organizations seeking a reliable, universal rack mounting solution at a very affordable price point, this kit represents a sensible investment. The design emphasizes compatibility over brand-specific tailoring, reducing inventory complexity for IT managers. The absence of proprietary components means replacement parts are readily available.
