Abstract: Systems and devices for mounting servers are provided. In one aspect, a rack mounting system includes a first mounting bracket attached to a rack. The rack comprises a rack front side and a rack rear side opposite the rack front side. The first mounting bracket is attached to the rack rear side. A rail bracket is attached to a server component mounted in the rack. A second mounting bracket comprises a first end and a second end. The first end is coupled to the first mounting bracket. The second end is coupled to the rail bracket. The second mounting bracket comprises a first surface and a second surface opposite the first surface. The first surface of the second mounting bracket contacts the first mounting bracket. The second surface of the second mounting bracket contacts the rail bracket.

Abstract: Examples described herein include handles with extended and retracted positions. In some examples, a handle comprises a housing and a knob. The knob may have a first surface and a circumferential sidewall. The knob may have a retracted position in the housing and an extended position. In the extended position, the circumferential sidewall protrudes from the housing and the knob is rotatable between a first position and a second position.

Abstract: An example rail kit includes a bracket assembly that is attachable to opposing columns of a device rack, a middle rail that is slidably engaged by the bracket assembly, and an inner rail that is connectable to an electronic device and slidably engaged by the middle rail. The rail kit may include a rail lock that is attached to the bracket assembly and that is to, when the inner rail is not engaged by the middle rail and the middle rail is located at a first position that is forward of a fully retracted position, lock the middle rail by engaging a depression in the middle rail such that the middle rail is prevented from sliding rearward. The rail lock may be released as a result of the inner rail being slid toward a retracted position while engaged by the middle rail.
