Patent number: 4908915Abstract: This invention provides several embodiments of a metal clip which is snapped onto a grid system and which anchors it through to place on a metal stud wall system. These metal clips makes it possible to erect metal studs of a housing and/or office construction without using electricity and without damaging the grid system so that the former can be removed and the ceiling of the construction does not have to be patched and/or replaced. In one embodiment of the metal clip, the metal clip has a pair of downwardly extending spaced spring sides connected together by a flat section. The spring sides are positioned over a cross metal beam and/or track. An upwardly extending clip is attached to the flat section and positioned in a fixed position for coupling of the grid system. In a second embodiment, the upwardly extending clip is made rotatable to connect to the grid system in different positions.Type: GrantFiled: September 9, 1988Date of Patent: March 20, 1990Inventors: Donald L.
