Written 23 Aug 2026. Specs from NavePoint and Amazon cards. Street from named snaps. I haven't hung this tray.
An extra tray for the 6U, not a 19-inch 10-inch-deep: NavePoint 10-inch shelf
The NavePoint 6U already ships two 10-inch shelves. Buy a third only if those two are full. 10-inch here is the rail width of a skinny wall cabinet, not a 19-inch tray labeled 10-inch deep.
Buy SKU 00406855 only if the two kit shelves are full. Amazon B0BNLZF1F1 printed $31.99 this pass. Maker card has printed $24.29 and gone empty. The 19-inch tray titled “10 inches (250mm deep)” will not hang here.
This tray is 10-inch wide. 44 lb class. Black powder coat. Box: 4× M6 screws, 4× M6 washers, 4× M6 cage nuts. UPC 810100701925. Amazon dimensions on the card are a lazy 10×10×10 in cube. Trust the 10-inch-width series, not that cube. The 6U’s max mount depth is still 7 in on the 11.8 in cabinet. A fat NAS brick will not sit even with a third shelf.
Search “NavePoint 10 inch shelf” and Amazon also returns 1U 19-inch cantilevers whose depth is 10 in. Example: universal tray B0794QJR33, ~$49, 17.5 × 9.75 in surface, “Fits all Standard 19" Racks.” That is the 19-inch 1U shelf job, not this cabinet.
What to buy
| Tray | What it is | Street, 23 Aug 2026 | Buy if |
|---|---|---|---|
| The two shelves in the NavePoint 6U | Cabinet kit already includes 2× 10-inch shelves + 1× blank. 44 lb class on the extra-tray card; cabinet overall 110 lb. | In the $161.99 11.8 in perforated box. Don't add a third tray first. | You just hung the 6U. Default. Use these two. |
| NavePoint 00406855 | 10-inch-wide spare shelf. 44 lb. M6 hardware in the box. UPC 810100701925. ASIN B0BNLZF1F1. | Amazon $31.99 this pass. Maker 00406855 has printed $24.29 and shown empty. Print the live tag. | Both kit shelves are full of pizza boxes, and you measured 7 in of rail left. |
| 19-inch 1U cantilever, 10 in deep | EIA 19-inch. Amazon titles say “10 Inches (250mm deep).” Surface ~17.5 × 9.75 in. ASIN B0794QJR33 is one of them. | That card ~$49. See the 19-inch shelf note. | You stayed on the StarTech 12U. Never for the NavePoint 10-inch rails. |
Skip
Skip a third shelf because the photo looks empty. Skip any “10 inch” tray whose spec also says 19-inch EIA. Skip glass-door extras, RGB, and eBay lots. Skip hanging a 19-inch UPS on this tray. If the wall will take 19-inch, the whole cabinet was the wrong buy. See 12U vs 10-inch.
