Corner bead

By James Grokman, CEO, TapeAndFloat · Updated 2026-10-28

Corner bead is metal, vinyl or paper-faced trim installed on outside corners to protect them and give a straight edge to finish to.

Why it matters on a drywall job

Bead is measured in linear feet and has its own labor, so it belongs in the takeoff.
Archways and bullnose corners take different bead and more time.
