Questions about this item
What hardware comes with the SPT-U300-2A and what tools are needed?
The shelf ships with all required screws and nuts; only a Phillips screwdriver is needed for installation.
How do I decide between the 2U height and other rack-unit sizes for my 19-inch rack?
The shelf occupies exactly 2U (3.5 in) of vertical space, so choose it when you need a single vented tray at that height in a standard 19-inch, 4-post rack.
What does the 50 lb weight capacity mean when the shelf is mounted in a cabinet?
The 50 lb (22.68 kg) rating applies to evenly distributed load on the 16 in (406 mm) deep vented steel tray when secured to all four posts of a 19-inch rack.
