What is a drywall flat box?

Put simply, a drywall flat box is an automatic taping tool that simultaneously applies joint compound to the wall while feathering the edges of your seam to a precise crown. They can significantly speed up the process of drywall finishing when compared to relying solely on hand tools. Just like with all automatic drywall taping & finishing tools, they're designed to make your drywall life that much easier and to help you complete your jobs that much faster.

How does a drywall flat box work?

To operate a drywall flat box, you first use your compound pump and filler attachment to fill your box with joint compound through the opening at the front of your box. After that, attach your box handle and you're ready to get started.

As you start moving your way down the wall or ceiling, you're applying pressure to the back pressure plate which forces the mud through the opening.

There's an adjustable blade tensioner that regulates the amount of joint compound that is applied; the higher the number, the less compound is applied to the wall.

What flat box sizes are available?

There are several flat box sizes available; most brands will typically carry 7", 10", 12" and 14" flat boxes. At LEVEL5, we offer both "Standard" and "MEGA" size flat boxes. MEGA Flat Boxes hold up to 50% more mud capacity vs Standard boxes which means fewer trips back to the pump. This additional capacity also means you can run your flat box further along the wall before running out of drywall compound.

Flat Boxes are also often available in either "Hinged" or "Unhinged" designs. Hinged flat boxes don't allow the pressure plate to be removes while unhinged do. Because of this, unhinged boxes are generally easier to clean. LEVEL5 flat boxes all featured unhinged designs.

What is a drywall flat box handle?

A flat box handle is the handle you use to control your flat box when it's pressed against the wall or ceiling. It operates by way of the pinch brake; if you pinch the break, it locks the head in place so the box can't move. If the break is released, the box can now swivel on the handle freely.

LEVEL5 Flat Box Handles are available in fixed-length as well as extendable sizes which can help you reach ceiling heights upwards of 12 feet high (without stilts).
