The QiaoYoubang 2 Pcs of 1U Universal Rack Shelf is designed to fit any standard 19-inch server rack or cabinet, making it a versatile choice for IT, data, and networking equipment. With a product size of 1U height x 19" width x 12" depth, and a usable size of W 17.2" x D 11.90", these shelves are perfect for non-rack mount equipment less than 12 inches deep.

One of the standout features is the ventilated design, which maximizes airflow to keep your AV or other equipment cool. Made from high-quality cold-rolled steel with a powder-coated finish, these shelves are built to last and can support up to 30 lbs. Assembly is straightforward, requiring only two steps to attach the holding brackets onto the shelf.

Customer reviews highlight several key points:

• Fit in the rack nicely.
• Good quality shelves, easy to install, keeps the equipment secure.
• Arrived well packaged and in good order. Assembly is a bit tedious but seems sturdy once assembled.
• Good shelving to add to rack. They are holding a good bit of weight despite only being front attached in my mounting situation.
• These are pretty flimsy. They might be okay for writing on a notepad, but I wouldn't use them to hold a laptop or other equipment.

Overall, the QiaoYoubang Universal Rack Shelves offer excellent value for money with their durable construction and easy installation process. While some users noted minor assembly challenges and concerns about weight capacity under maximum load conditions (30 lbs), most found them reliable for typical usage scenarios involving lighter loads such as small PCs or PoE switches within server racks.
