Abstract
A filter tube frame for use with a filter bag house. The filter tube frame includes an end cap having a pivotable handle attached thereto to facilitate removal of the tube frame from the bag house. The handle includes a lever surface adapted to engage a tube sheet surface, thus, during use, providing a force to urge the end cap away from the tube sheet and unseat the filter tube frame from the tube sheet.
