Raising Electronics Fixed Rack Server Shelf 1U 19Inch Shelves 4 Post Rack Mount Adjustable Deep for Network (24-30Inch Depth)

The shelf is heavy duty and well made. Highly recommended.

This is exactly what I was looking for, just be sure your not like me and install it upside down.

It says it's rated for 175 lbs, but I wouldn't trust it any more than it weighs. I mounted it on the rack and put a tower server on it. It immediately sags to the middle like a worn-out mattress. I have a 30" rack, and the adjustable rails look like they want to bend and bow out. The equipment is heavy, but not 175 lbs heavy and I do not trust this shelf to hold it for any time.

Seem like good quality shelves, but shipping was poor. My box was half open on arrival (not much tape on the box) and one of the metal were you mount the screws was bent at 45 degrees. Had to bend it back with pliers.

I bought the 24-30Inch Depth version and I use it in a 24 inch deep rack. The shelves are very sturdy in this configuration. If you need to extend them to 30 inch expect to see some deformation of the side brackets because they are not very long.
