This is a 4U rack case from SKB. It has stays on both sides for screwing in equipment. 14 screws and receivers are included. There are no functional problems, and there are no holes or cracks. There are scratches, but I didn't see any major ones. I bought it used in good condition about a year ago and used it for about six months. I will wrap it in bubble wrap and ship it. External dimensions: Depth: Approximately 56cm Width: Approximately 54cm Height: Approximately 24cm Internal dimensions: Depth: Approximately 40cm Width: Approximately 48.5cm Height: Approximately 17.8cm
