This is the most economical and flexible 4U rack I have ever seen. It reaches 13.5 inches, allowing for a wider range of equipment, shelves, etc. than fixed-depth units. The products are heavy duty, well built and use standard bolt holes instead of the always troublesome cage nuts. Bought several and now consider this my main source for small wall shelving tasks.
