APC by Schneider Electric AR8128BLK Heavy Duty Sliding Rack Shelf

Overview

The APC by Schneider Electric AR8128BLK is a 1U heavy-duty sliding rack shelf rated for 185 lbs of static load — purpose-built for commercial rack enclosures where you need a stable, pull-out surface for dense or awkward equipment that wasn't designed to be rail-mounted. At 445 mm wide and up to 711 mm deep when extended, it gives you enough real estate for network appliances, test gear, UPS batteries, or any rackmount-adjacent device that needs a flat platform.

Key Features

• 185 lb (84 kg) load rating: handles dense network appliances, multi-drive storage arrays, or heavy test equipment without deflection — well above the typical 50–75 lb capacity of standard fixed shelves in this form factor.
• 1U rack profile (44 mm height): consumes a single rack unit, leaving adjacent slots available for patch panels or blanks. Tight rack real estate is not wasted on a thick shelf chassis.
• Sliding extension to 711 mm depth: pulls the shelf forward so you can access rear cabling or service equipment without removing it from the rack — reduces downtime during moves or maintenance cycles in rack accessory dense environments.
• Mounting depth adjustability (28–40 mm): accommodates the post spacing variation you'll encounter across rack brands; no adapter kit required for most standard 19-inch enclosures.
• 445 mm usable width: matches standard 19-inch rack interior clearance, so equipment sits flat without overhang or shimming.
• All-metal construction, black finish: consistent with equipment-room aesthetics; steel housing resists the flex and creep that plastic-bodied shelves develop under sustained load.
• No lock, no casters: fixed-position slide mechanism — appropriate for stationary rack enclosures. If you need a locking shelf or a mobile cart, this is not the right unit; plan accordingly during your rack planning phase.

Integration & Compatibility

The AR8128BLK is compatible with standard 19-inch EIA-310 rack enclosures. Minimum mounting depth is 28 mm and maximum is 40 mm — verify your rack's post depth before ordering. The shelf has no power, no switching, and no network connectivity; it pairs with rack enclosures and PDUs as a passive platform only. It does not include a cable management arm — route cables manually or add a dedicated arm if needed.
