StarTech.com 1U 19 inch Server Rack Rails - 24-36 inch Adjustable Depth - Universal 4 Post Rack Mount Rails - Network Equipment/Server/UPS Mounting Rail Kit HPE ProLiant Dell PowerEdge (UNIRAILS1UB)

Doddle to install, just pull them out longer than you need, screw one end into rail, go to other end of rack, adjust length by pushing/pulling as required and screw them in. Mine came with exactly the right number of screws and cage nuts (8) so don't lose any. Already have a pair of these holding a UPS so knew they would be good. This pair will hold my PC which is in a 4U case.

Prefect rail for all types of server rack equipment. Markings on the levels assist with placement

I have a long (100cm deep) home lab rack and needed to mount a short (45cm) and heavy Cisco switch to it. Since there is very little out there and I already have a StarTech rack, it made sense to continue with a StarTech generic, adjustable rail. Mounting the switch with the rails inwards, and sides pointing upwards, as anyone would reasonably expect, ended up pushing the switch and its mounts upwards by about 2-3mm, making it impossible to attach the whole lot to the rack. The only way that worked was to flip the rails so the sides were pointing downwards and the switch was resting on top of the rails, losing an entire 1U section to an empty slot where the rails now are. To top it off, the adjustable sides have two sets of screws to hold them in place and NONE of them work properly. The rails will slide all over the place as the screws won't physically tighten any furhter than they are when you receive the product. I am really disapointed in this product but am strapped for options available. I don't want to buy another one but have little choice if the problem arises with some other future components.

Ottime slitte: robuste e facili da montare. Come suggerito in altri commenti, le ho montate rivolte verso il basso per permettere l'allineamento del server con le guide verticali del rack.

Nice and sturdy, I use it to support a big and heavy UPS in my rack

Fait le job, aucun problème.

Usla. Utrymmet blir för smalt och för lågt.

I purchased two pairs of StarTech UNIRAILS1UB 1U server rack rails in early 2026 for use with my StarTech 12U rack stand. The build quality is excellent, as I have come to expect from StarTech products. The rails feel very solid, are easy to install, and the adjustable depth design makes them convenient to use with different rack configurations. The rails are currently supporting NAS systems equipped with multiple Seagate IronWolf Pro hard drives, and they have performed perfectly. They feel strong and stable, even with heavy equipment installed. Combined with the already sturdy StarTech 12U rack stand (rated at approximately 550 kg, if I remember correctly), they provide a very reliable mounting solution. I have had no issues with installation, strength, or overall quality. I am very satisfied with this purchase and would gladly recommend the StarTech UNIRAILS1UB rack rails for server, NAS, or networking equipment.
