Description
A flat box is used in conjunction with a flat box handle to efficiently apply a crowned, feathered coat of joint compound over taped flat seams on walls and ceilings.
The MEGA capacity flat boxes can hold approximately 30% more compound than standard capacity flat boxes, enabling few trips back and forth to the pump. The trade off is that MEGA capacity fla boxes are bulkier and heavier when full due to their increased height. Ultimately, the choice between the two styles is a matter of personal preference.
