A clamping device for stainless steel sinks having rolled rim edges used for suspension of weighted items from a sink's rolled rim edge for better organization around the sink work area comprising, a hanger bracket, a compression gib, and a fastening means. The hanger bracket is further defined by a front having an elongated vertical slot, a supporting member, and a crispate top. The compression gib includes a generally horizontally disposed bracing arm having an integral arm which extends upwardly and vertically in relation to the bracing arm. The integral arm further has an elongated vertical slot which extends the length along a longitudinal axis. Attached to the upper most portion of the integral arm is a crispate top which is substantially identical in configuration and shape, to the arcuate portion of the underside of the rolled rim sink to which it is attached. The fastening means is received by the slots of the hanger bracket and gib and detachably holds the device together. The various components of the present invention, and the manner in which they interrelate will be described in greater detail hereinafter.
