Abstract: A cage nut fastener includes a nut and a spring cage comprised of a back wall with a wall aperture therethrough, first and second hooking arms disposed at opposite sides of the back wall, and one or more cage arms. At least one of the hooking arms includes a compressible lever, and each hooking arms terminates with an outwardly-oriented hooked portion at a front of the nut. The nut is retained at a caged location by at least the one or more cage arms and includes a nut aperture therethrough in alignment with the wall aperture of the back wall. Application of a compression force upon the lever, without the aid of tools, manipulates the spring cage to a compressed state that facilitates positioning of a distal end of one or both of the hooked portions through an aperture of a frame member.
