Rack Shelf — 1U and 2U Vented Shelves for 19-Inch Racks
1U and 2U vented rack shelves for switches, routers and non-rack equipment, with front and rear mounting.
Rack shelves are 1U or 2U 19-inch trays for equipment that is not rack-mountable. A 1U vented shelf typically carries 30 kg to 50 kg; a 2U shelf carries 50 kg to 80 kg. Choose vented shelves for active equipment and solid shelves for tools.

Not every device has rack ears. Shelves carry switches, routers, power supplies, test equipment and small UPS units inside the cabinet.
Vented shelves improve airflow; fixed and sliding versions serve different service access needs. Rear support brackets reduce deflection on deep shelves.
Best for
- Switches and routers without rack ears
- Test equipment and small UPS units
- Cabinets that need flexible equipment layout
