APC AR8122BLK Fixed Shelf 250lbs 114kg Black server accessory

Fixed Shelf 250lbs 114kg

The APC AR8122BLK is a ventilated fixed shelf finished in black that occupies 1U of rack space. It supports a load capacity of 250lbs or 114kg and mounts to four-post racks with adjustable mounting depth. This accessory suits server rooms and network cabinets that need sturdy, open shelving for non-rackmount equipment.

Upgrade From Floor Placement

This shelf replaces ad-hoc stacking or floor placement of hardware inside a cabinet. The jump is worth it when equipment lacks rack ears but must sit securely inside a standard enclosure. Ventilation slots allow airflow through the shelf, reducing heat build-up compared with solid surfaces. Adjustable depth lets the installer match varying rail positions without modification.

Build Integration

The unit fits any four-post rack offering 1U clearance and accepts the adjustable mounting depth range provided by the rails. It frees up vertical space by consolidating devices onto a single ventilated tier. Cable management accessories and thermal management accessories can be added around the shelf to complete the enclosure solution. No specific rail depth or rail type is mandated beyond the adjustable range.
