X-2 Corner Beads for outside corners have a smooth round nose bead with Diamond Mesh wings for the keying of plaster right up to the nose of the bead. This mesh insures a perfect bond and provides effective reinforcement where most needed. Especially recommended in fireproofing columns and beams. Rigid straight edge nose is easy to install and permits plumb straight outside corners. Excellent protection for corridor corners exposed to traffic. X-2 Corner Bead is superior to X-1 due to the added stiffener strip that affords additional rigidity to the flange. The flange width is 3-1/4" wide and is easier to form, install and keep straight than traditional corner beads.
