Abstract: An improved assembly is disclosed for clamping the perimeter flange of a sink snugly down upon a countertop where the sink is being installed. The assembly utilizes a stud extending downwardly from the underside of the perimeter flange and a link connected to the stud having a displacement member, such as a threaded bolt, which engages the underside of the countertop adjacent the hole in the countertop where the sink is located. As the displacement member is manipulated against the underside of the countertop, the link holding the displacement member draws the stud downwardly to pull the flange snugly against the upper face of the countertop adjacent the sink installation hole.

Abstract: A device for securing a sink bowl in a counter top wherein a base unit has an annular inclined planar upper surface with a central stud extending therefrom. The stud engages a channel fixed to the underside of the sink flange such that when the base unit is rotated the inclined surface increasingly bears against the underside of the counter top drawing the sink flange into positive engagement with the upper surface of the counter top.

Abstract: A clamp in the form of a generally L-shaped bracket or clip made preferably of a single stamping of spring steel or like material and provided with a threaded member, threading through the base of the bracket or clip. The top of the bracket or clip is provided with an angularly inwardly projecting integral portion terminating in a slightly downwardly bent flange forming a hook. The clamp is used principally for holding a sink bowl, or the like, in an opening in a counter top by cooperating with a generally L-shaped angle-iron strip welded to the underneath of the sink bowl flange. For removably holding the sink bowl in the opening in the counter top, the hook end of the clamp bracket body is engaged behind an inwardly bent flange portion of the angle-iron strip and the threaded member is tightened against the lower surface of the counter top proximate the opening.

Abstract: A plug for closing an opening or hole in a panel, plate or wall, comprising a head portion and a shank portion. The head portion has a peripheral flange forming an internal groove in which is disposed the edge of an annular base portion of the shank portion, the annular base portion being split and elastically compressible for engaging, during assembly, the edge thereof within the groove when the annular member is allowed to relax to is original dimension and shape.
