US Patent 6840388 Tool-less rack mounting system

A tool-less rack mounting system includes a grooved bullet attached to a flange on the end of a slide rail assembly. The bullet protrudes through a clearance hole formed on a corner post of a rack. A hand-releasable clip engages the groove, retaining the bullet in the clearance hole and retaining the flange against the post. The clip may be mounted to a bracket, and the bracket may include features for securing equipment in the rack. A hinged cable management arm may be mounted to the post and to the slide rail assembly without using tools. A flange on one end of the arm includes a clearance hole opening into a channel. The channel engages a standoff mounted to one of the rails of the slide rail assembly. A flange on the other end of the arm may be retained against the post by the bullet and the hand-releasable clip.
