A-Lok is a flexible compression connector used for connecting RCP (Reinforced Concrete Pipe) and RCAP (Reinforced Concrete Arch Pipe) to precast storm structures. For years similar flexible connectors, also known as "boots", were specified by engineers to connect smooth wall PVC sewer pipe to precast concrete manholes. A-Lok has introduced the same concept to precast concrete storm systems with their A-Lok STM storm connectors.
