The A●LOK STM is a flexible pipe-to-manhole connector designed for the prevention of soil and water infiltration into stormwater sewer systems. It can be used with both round and elliptical shaped pipes and curved and flat wall structures. It is available for 8" diameter and larger pipes.

KEY ADVANTAGES

The A●LOK STM Connector functions on pure compression, making field installation quick and easy. Just clean and lubricate the connector and pipe, bevel pipe, center the pipe in the connector, and insert. This rapid installation permits immediate backfilling, enhancing project safety and overcomes the normal problems encountered with water, running sand and other unstable trench conditions. This results in shorter job projections, while mininizing traffic interruption and cost overruns.

The A●LOK STM provides up to 10° of omnidirectional deflection while still maintaining a watertight seal. This design allows the connector to compensate for shear due to settlement or ground movement preventing water and soil infiltration into the sewer system. This proper pipe to Structure connection minimizes the chance of pothole formation and sediment build-up in the storm system, saving states and municipalities money over the life of the structure.

On larger diameter pipe when size prohibits a gasket from being installed in a flat plane, an A●LOK STM Connector can be configured for casting in a curve with the connector staying perpendicular to the center line of the pipe. This design has resulted from years of extensive research and development and causes no loss of compression or deflection.
