Used as a finished edge for wallboard at door and window openings or when gypsum panels meet dissimilar surfaces

Hemmed-edges allow for quick installation and do not require joint compound for finishing.

  • Requires no joint compound.
  • Galvanized for corrosion protection.
  • Hemmed edges for quick installation.
