Claim 0:
1. A device configured to be mounted to a planar mounting panel, the device comprising:
a housing configured to be received in an aperture in the mounting panel, the housing including a housing aperture and a recess;
a threaded fastener disposed in the housing aperture;
a dogleg tab including a lateral flange extending approximately perpendicular from the fastener and a longitudinal flange extending perpendicular from the lateral flange and parallel to the fastener; and
a friction inducing member friction-fit to the fastener, wherein:
the dogleg tab is configured to be disposed in a retracted position in which a surface of the longitudinal flange of the dogleg tab is disposed to engage the recess with a friction force configured to retain the dogleg tab in the retracted position, and to be disposed in an engagement position, in which the dogleg tab is disposed to engage an inside surface of the mounting panel;
the friction inducing member is friction-fit to the fastener with a force of friction greater than or equal to a first threshold force; and
the first threshold force is greater than a downward force of gravity acting on the dogleg tab.
