StarTech.com UNIRAILS1U — Universal 1U Rails for Equipment That Came Without Its Own
1U · 19-inch420–1100 mm depth25 kg loadUniversal fit
The StarTech.com UNIRAILS1U is a set of 1U universal rack rails with an adjustable mounting depth from 420 mm to 1.1 m and a 25 kg static load rating, for mounting servers, appliances or older OEM equipment whose original rail kit is missing or discontinued.
Instead of relying on a vendor-specific slide kit, the two L-shaped rails fix to the front and rear posts of a 19-inch rack and the equipment rests on them. StarTech states they suit non-rackmount equipment and discontinued OEM gear from brands such as Dell, IBM, HP and Apple. The rear section includes a removable panel for cable management.
Before you order: The rails need both front and rear posts at a spacing between 420 mm and 1.1 m, so they are for 4-post racks and cabinets, not 2-post relay racks.
What's in the Box
- 1 × set of universal rack rails (left and right)
- 8 × M5 panel screws
- 8 × M5 cage nuts
- 1 × M5 wrench
What It Means in Practice
- The device rests on the rails, so it slides in but is not on ball-bearing slides — you pull it out fully to service it.
- Measure your post-to-post depth before ordering: 420 mm minimum, 1.1 m maximum.
- 25 kg per 1U covers most 1U servers, firewalls and appliances.
- Secure the device front ears to the rack as well, where it has them.
What Will Not Work
- 2-post racks — there is no rear post to fix to.
- Loads above 25 kg.
- Rack depths under 420 mm (shallow wall cabinets).
- Tool-less or ball-bearing slide operation — these are static rails.

Frequently Asked Questions
Are these sliding rails?
No. They are fixed support rails; the equipment rests on them and slides in and out on the rail surface.
Will they fit a shallow wall cabinet?
Only if the distance between front and rear posts is at least 420 mm.
Do I get both sides?
Yes, one set includes left and right rails plus M5 hardware.
Singular Expert Insight · Buyer's Guide
Universal rails are the practical answer when a used or older server arrives without its rail kit. Measure post-to-post depth first, then check our
rack accessories range for blanking panels to fill the gaps around it.
✓ Buy it if you need to mount a 1U device up to 25 kg in a 4-post rack and have no vendor rails.
✕ Skip it if you have a 2-post rack or need tool-less slide-out servicing.
→ Also consider a depth-adjustable 1U 4-point shelf such as EFB 691653TS.80 for heavier loads.
