Orion® sinks are molded from durable polyethylene. They are easy to install and are designed to provide years of tough service. Several models of ADA compliant sinks are included in the line. Laboratory sinks are designed for intense chemical environments and are produced from virgin polyolefins with an integral 1-1/2 in national pipe thread outlet. The corner drain location allows for the maximum use of the sink bowl. An integral flange permits either flush above the counter mounting, using a stainless steel flush mounting rim or traditional below the counter mounting. Flush stainless steel or undercounter steel mounting rims are available for all sinks and are recommended by Orion® for installation.
