Typical wall penetration with mechanical duct

A method and apparatus for eliminating register boxes, improving penetration sealing, improving airflow and reducing the labor costs to install ceiling registers is disclosed. A collar plate assembly that interfaces with flexible or metal air ducts is provided with at least one spring indentation ring in the collar portion of the assembly to accept two or more locking springs. These locking springs are used to attach the ceiling register to the collar plate assembly. The collar plate assembly uses mounting rails that attach the assembly to either ceiling or wall supports. After the ceiling or wall material is applied, the circular area inside the collar is cut-out to provide access. A trim ring is inserted in the cut-out that attaches between the collar and the ceiling or wall to eliminate air leakage and provide an essentially smooth flow of air from the supply duct into the inside of the structure.
