Abstract
A retainer clip includes a ratchet plate and a cooperating pawl for anchoring a sink to a countertop with a press-in, above-counter installation. The ratchet plate has a plurality of detents and is affixed to an edge of a cutout in the countertop. The pawl includes a spring element mountable to the sink and has at least one upwardly angled, resilient tab which successively engages the ratchet plate detents with a one-way action as the sink moves downwardly in the cutout. When the sink is fully inserted, the tab seats upwardly in a detent of the ratchet plate. In an embodiment, the pawl includes multiple tabs having slightly different lengths to provide an installation tolerance that is less than an incremental distance between ratchet plate detents.
