Description – Drywall Flat Box

A Drywall Flat Box, sometimes known as a finishing box or automatic flat box, is a tool used to apply and smooth joint compound over drywall seams and surfaces. Constructed from high-grade aluminium or stainless steel, it provides strong, lightweight performance for professional finishing work.
