Bilco PermEntry® Basement Entrance

    Choosing the Correct Size

How To Measure:
  • Determine the measurement from the finished grade to the foundation footing.
     
  • Refer to the table below to select the proper size. The top of the casting should be a minimum of 2" above the finished grade.
     
  • Double check the PermEntry Job Site Requirements and check site to determine if there is proper truck access to and from the PermEntry installation area.
