Abstract
A polymeric trench drain for use in a trench drain system. The trench drain includes an open-faced channel having a crushing rib. The crushing rib prevents buckling of the trench drain due to changes in temperatures. The trench drain also includes removable spacer blocks for use during installation, which prevent the trench drain channel from deforming during installation. Rebar clips and securement clips are provided for easy installation. A unique profile is provided on support ribs to assist in easy stacking of the trench drains prior to installation.
