This 2-pc kit covers 2U of rack. The well-machined pieces fit snugly against each other, without any sharp edges or obvious flaws. There are 4 holes per panel, but you only need to secure 2 of them to keep the panel stable. Mounting hardware is included, including "cage nuts" for square-hole racks. If you need many 1U panels and have a square-hole rack, the 10-piece snap-in plastic panel kit is much cheaper, and easier to move around. The [[ASIN: B00006BBKF 4-pc 15U]] blanking kit is a better choice if blocking off large parts of a round-hole rack. Marked down one star for being rather expensive for 2U of panels, and inconvenient on square-hole racks. Recommended for round-hole racks.
