Trench Former

ABT Inc, is currently the only trench drain manufacturer to make assemblies that address the issues of expansion joints and control joints.  In addition, all trench former product families have prefabricated "Tee" and "Turns" and have a load carry bar that addresses the structural weakness typically caused by these joints.
