DIGITUS 1U Shelf with Variable Rails for 19" Cabinets, 50 kg, Grey RAL 7035
1U · 19"50 kg load4-point fixingCabinets ≥ 1000 mm
The DIGITUS DN-97648 is a 1U fixed shelf with adjustable-depth mounting rails for 19-inch network and server cabinets of 1000 mm depth or more, carrying up to 50 kg on a perforated steel tray in light grey RAL 7035 — the standard way to hold a non-rackmount server, NAS, UPS, modem or desktop PC securely inside a rack.
Because it is fixed at four points, front and rear, the load sits on all four 19" profile rails instead of hanging from the front ones, which is why it can take 50 kg. The rails slide to match the distance between your front and rear rails, up to a mounting depth of 900 mm, and the full M6 installation set is in the box.
Before you order: This shelf needs front AND rear 19" rails in a cabinet of at least 1000 mm depth. It will not fit a 600 or 800 mm deep cabinet, a wallmount cabinet or a 2-post open frame. For shallower cabinets DIGITUS makes other depth versions — send us your cabinet model and we will pick the right one. Make sure you order the colour that matches your rack: DN-97648 is Grey RAL 7035, the black version is DN-97649.
What's in the Box
- 1 × 1U shelf with variable mounting rails (Grey RAL 7035)
- Installation set: M6 screws, cage nuts and washers
What It Means in Practice
- 50 kg spread over four mounting points is enough for a tower server, a NAS with drives or a heavy line-interactive UPS.
- The perforated steel tray lets air pass through, so equipment on the shelf does not trap heat against the tray.
- Only 1U of rack height is used by the shelf itself; the device sitting on it uses whatever height it needs above.
- Adjustable rails mean the shelf also works if your rear rails are not at the factory position.
What Will Not Work
- It will not fit cabinets shallower than 1000 mm or racks without rear 19" rails.
- It is a fixed shelf — it does not slide out for service access; for pull-out access choose an extendible shelf.
- It will not fit a 2-post relay rack or wall bracket.
- The 50 kg rating assumes 4-point fixing; hanging it from the front rails only is not a supported installation.

Frequently Asked Questions
Will it fit my 800 mm deep cabinet?
No. DIGITUS specifies this shelf for cabinets from 1000 mm depth. Tell us your cabinet model and we will recommend the matching depth.
Does it come with screws?
Yes — an installation set with M6 screws, cage nuts and washers is included.
Can I put a UPS on it?
Yes, as long as the unit is within 50 kg and the shelf is fixed at all four points.
Singular Expert Insight · Buyer's Guide
Fixed 4-point shelves are the workhorse of mixed racks: anything without rack ears — a tower server, an ISP router, a NAS — ends up on one. The mistake we see most is ordering the shelf before measuring the cabinet depth. Browse the other shelves, blanking panels and cable managers in our
rack accessories range to complete the build.
✓ Buy it if you have a 19" cabinet of 1000 mm depth or more and need to hold equipment up to 50 kg.
✕ Skip it if your cabinet is 600 or 800 mm deep, has no rear rails, or you need a pull-out shelf.
→ Also consider DN-97649 (same shelf in black RAL 9005), or a DIGITUS extendible shelf if you need service access.
