QNAP RAIL-B02 Standard Slide Rail Kit for Rackmount NAS
QNAP slide rails443–815 mm depthSquare + round holes1U / 2U NAS
The QNAP RAIL-B02 is the standard-depth slide rail kit for many QNAP 1U and 2U rackmount NAS models, fitting 19-inch racks with a post depth of 443 to 815 mm and both square and round mounting holes, for anyone installing a QNAP rack NAS properly on rails instead of on a shelf.
Slide rails carry the NAS along its full depth and let you pull it out of the rack for drive or memory service without disconnecting it from the frame. Because rails are matched to the chassis of each NAS family, the key question is not the rack but the NAS model — check the list below.
Before you order: RAIL-B02 is not universal. It fits only the QNAP models listed by QNAP, and needs a rack with a nominal depth of at least 450 mm. For shallower racks QNAP specifies the RAIL-S02 kit; short-depth models such as the TS-x51DeU use other rails.
What's in the Box
- 1 × QNAP RAIL-B02 standard slide rail kit (left and right rails)
- QNAP does not publish a detailed package list for the mounting hardware
What It Means in Practice
- The rails adjust to a front-to-rear post distance of 443–815 mm, which covers most 600–1000 mm deep server cabinets.
- Works in racks with 9.5 mm square holes (cage nut type) and 7.1 mm round holes.
- At the shortest setting the rear of the rail can extend past the rear post, so leave some clearance behind the rack.
- Rack requirements from QNAP: post width at least 451 mm, panel width at least 485 mm, 465 mm hole centre-to-centre.
- Compatible models include TS-x53BU, TS-x32XU, TS-x63U, TS-x73U, TS-x77XU, TS-x83XU, TVS-x71U, TVS-x72XU and UX-800U/UX-1200U expansion units, among others listed by QNAP.
What Will Not Work
- Racks with a nominal depth under 450 mm — use QNAP RAIL-S02 instead.
- QNAP models not on the compatibility list, including short-depth TS-x51DeU units.
- Other brands of NAS or servers — the rails are shaped for QNAP chassis.
- 2-post racks — slide rails need front and rear posts.

Frequently Asked Questions
Does my QNAP NAS come with rails already?
Some QNAP rackmount models include rails and some do not. Check your NAS box or send us the model and serial and we will confirm whether RAIL-B02 is needed.
Will it fit my 600 mm deep cabinet?
Usually yes, if the distance between front and rear posts is at least 443 mm. Measure post to post, not the outside of the cabinet.
Can I use it for a Synology or Dell server?
No. The rails are designed for QNAP chassis only.
Singular Expert Insight · Buyer's Guide
With rail kits, the NAS model decides everything. Confirm your exact QNAP model against the list before ordering and measure the post-to-post depth of your rack. If the rack is shallow, RAIL-S02 is the correct kit. For shelves, cage nuts and blanking panels see our
rack accessories.
✓ Buy it if you have a listed QNAP 1U or 2U rackmount NAS and a 19-inch 4-post rack at least 450 mm deep.
✕ Skip it if your QNAP model is not on the list, your rack is shallower than 450 mm, or the NAS is another brand.
→ Also consider QNAP RAIL-S02 for short-depth racks, or a heavy-duty rack shelf if rails are not an option.
Send us your QNAP model and rack depth and we will confirm the correct rail kit before you order.
