Asgard 12-inch MaxxBox Finishing Box

The Asgard 12-inch MAXXBOX Finishing Box applies finish coats of joint compound to flat seams and butt joints while carrying more joint compound between fills. Its high-capacity body holds up to twice the usable compound of an Asgard Classic box, helping drywall crews run more footage before returning to the loading pump. The wider 12-inch pass helps blend the finished joint into the surrounding drywall face and also supports wider skim work.

An adjustable crown dial controls mud output and the amount left over the center of the joint. The finishing blade feathers both edges as the box moves, while anodized aluminum components and quick-release thumb latches provide a durable, serviceable design for daily automatic drywall finishing.

Fill the MAXXBOX from a compound loading pump through a filler adapter and operate it with an Asgard or compatible major-brand flat-box handle. The universal-style connection makes the higher-capacity box easier to add to an existing finishing setup.

Asgard offers a more affordable option for contractors who want longer runs between fill-ups without stepping away from a professional flat-box system.

Key Features

• Application: Applies finish coats to flat seams and butt joints
• Working width: 12 in for wider finish and skim passes

How It Works

Run the box with the wheels leading and the blade trailing. The crown dial adjusts the amount of compound left at the center of the joint, while the blade feathers both edges.
