Asgard 7-inch Flat Finishing Box

The Asgard 7-inch Flat Finishing Box is an automatic drywall finishing box for applying base coats of joint compound to flat seams and around corner bead. As the box moves over the joint, it dispenses joint compound, levels the center, and feathers both edges in a consistent 7-inch pass. Its narrower working width provides controlled coverage where a larger finishing box may be harder to place.

An adjustable crown dial controls how much compound remains over the center of the joint, giving the finisher direct control over the finished profile. The aluminum box uses anodized components for jobsite durability, and quick-release thumb latches open the pressure plate for faster cleaning and service.

Load the box from an Asgard Compound Loading Pump through a Filler Adapter, then connect it to an Asgard or compatible major-brand flat-box handle. The universal-style attachment makes it practical for crews adding Asgard finishing boxes to an existing automatic drywall tool setup.

Asgard offers a more affordable option for contractors building or expanding a professional automatic finishing system.
