The Perfect Drain from Elkay is an edgeless drain without a rim. The smooth surface reduces the chance for breakage that can occur when placing glass on a traditional drain. Included with all Perfect Drain sinks is a strainer kit compatible with all InSinkErator disposers. It can easily be installed using the company’s Quick Lock mounting system. Available in top-mount and undermount options as well as in both single- and double-bowl configurations, the design is offered on more than 30 popular Elkay sink models.
