PRO-90 Archway

Used to finish arches, curvatures and most radius conditions

PRO-90 Archway corner bead (VLAB) (formerly known as CB125A) is an extra rigid vinyl archway designed with slotted flanges that easily forms to curves and arches. The radius on the nose aides in smooth and easy finishing.


The notched single flange adapts to virtually any radius condition. Multiple perforations along flanges and notches enhance compound and veneer plaster bonding. In addition to nail or staple fastening, an adhesive should be used to secure arch tabs to gypsum board.

  • Ideal for archways, curves and radius windows.
  • Maximum flexibility.
  • Rust proof and dent resistant.
