the stud are nearly directly opposite each other and also are generally perpendicular to the sides of the stud such perpendicularity to the engaged stud surface is accomplished via the curved component 34 of springs 28 since the presence of the stud in stud cavity 20 forces springs 28 directly outwardly rather than at a 45 or less degree angle to the side of the stud by the configuration of teeth 18 and 30 their respective tapered ends will dig into the stud even further should box assembly 10 be moved or loaded this arrangement provides for assured and continued gripping of the stud after initial installation bracket 14 may also be configured with alignment indicia not shown so that the installer can readily position box assembly 10 at the correct location on the stud such indicia may take the form of a line a marker a slot an opening or something else the chosen design being determined by the manufacturer from a variety of possibilities one unique feature of box assembly 10 is that it is designed so that flange 26 is not readily deflected outwardly from the stud which would result in a reduced gripping force of teeth 18 and 30 upon the stud this is accomplished in this embodiment by teeth 30 being secured to springs 28 such that the deflection that occurs and hence the bias that is generated is primarily in the curved component 34 of the springs 28 and not in its straight portion 32 or in flange 26 such engagement will result in an installed box assembly 10 that complies with code requirements that address resisting removal and or movement it should be understood that while box assembly 10 has been.
