StarTech.com CABSHELF22 — Deep 2U Fixed Shelf for 19-inch Racks, Front Mount
2U · 19-inch559 mm deep22.6 kg loadFront mount only
The StarTech.com CABSHELF22 is a 2U fixed cantilever shelf for 19-inch racks and cabinets that holds equipment up to 559 mm (22 in) deep with a 22.6 kg load rating, for placing longer desktop units, monitors-in-rack, routers or small appliances where a shorter shelf would leave them hanging.
It fixes to the front rails only, so it suits both 2-post and 4-post racks without rear supports. The trade-off for the extra depth is a lighter load rating than StarTech's heavy-duty 457 mm shelf, so it is best for longer but lighter devices. The lips face downward, leaving the full tray surface flat.
Before you order: The load rating is 22.6 kg — for UPS units or heavy appliances choose the CABSHELFHD (56 kg, 457 mm deep) instead.
What's in the Box
- 1 × 2U rack shelf
- 4 × M5 screws
- 4 × M5 cage nuts
- 1 × instruction manual
What It Means in Practice
- 559 mm of depth takes longer devices such as desktop towers laid flat or deeper firewalls without rack ears.
- 443 mm usable width between the rails.
- Front-only fixing: keep the heaviest part of the device toward the front rails.
- Check your cabinet depth — the shelf plus cables must still let the rear door close.
What Will Not Work
- Loads above 22.6 kg.
- Sliding or pull-out access — it is a fixed shelf.
- 10-inch or 23-inch racks.
- Racks without M5 cage-nut holes, unless you supply matching screws.

Singular Expert Insight · Buyer's Guide
Pick a shelf by two numbers: device depth and device weight. This one wins on depth; if the weight is closer to a UPS than a router, step up to a heavy-duty model from our
rack accessories range.
✓ Buy it if your non-rackmount device is longer than a standard shelf but under 22.6 kg.
✕ Skip it if the device is heavy (UPS, large server) or you need a pull-out tray.
→ Also consider the StarTech.com CABSHELFHD (56 kg, 457 mm deep) or a 2-post centre-mount vented shelf.
