Here is a video from Dell on how to install our Dell Precision Tower 7910 Rails. The sliding rails are compatible with Dell T7600, T7610 and T7910. Our rails mount in any EIA-310, 19″ rack with square, round or threaded holes. The tower is secured to the rails with screws on the side of the chassis. The rails for the Dell T7600 has a mounting depth range of 12 – 31″ (304 – 787 mm) and all hardware for install is included.
