Raised Base Flanges

Our raised base flanges are raised to allow for a 3/16" thick anchor plate to be used along with the flange. They have a neck and are available plain (center hole only), or in a 2, 3, or 4 mount hole pattern. Overall heights vary depending on size. Steel and aluminum are made from 19 gage material and stainless steel is 11 gage material.
