CM-1 Manway

Chase Associates Quick-Opening Model CM-1 Manways open into the vessel and seal an ASME flanged and dished cover against a liquid-tight, replaceable gasket. The handwheel release operates only when the tank is empty and provides access in seconds without unbolting or use of tools. Conforms with OSHA Permit Required Confined Space Rules.

Model CM-1 Manways are designed for vertical wall installations into Poured Concrete Walls, Block Walls and Precast Concrete Panel Walls in new or existing tanks. Each Model CM-1 is fabricated to meet the specific application requirements including type of material, wall thickness, tank radius, static head pressure and the correct gasketing for the tank contents.
