"42U" racks are the standard ones, with "U" equaling 1.75 inches. These can theoretically hold up to 14 servers. The "42U" rack is 73.5 inches tall and is the most sold one meant for the data centers. The 42U rack comes with a four-point locking system. It is highly compatible with all server manufacturers' equipment. The 16-fold frame design offers multiple internal points and surfaces for seamless mounting processes. The eye bolts are meant for securing the rack. The presence of an integrated channel right above the horizontal frame section helps prevent liquid collection on the gasket or liquid penetration due to the opening of side panels.
