A. Wide Flange Bullnose

(90° Outside Corner)

Flannery's Wide Flange Bullnose was our original bullnose corner. We call it "Wide Flange" because of its wider 7/8" nailing flange, which is 1/4" larger than typical bullnose cornerbeads. Many trim installers prefer the larger flange, since it gives them a larger fastening surface. Wide Flange Bullnose Corners have the same 3/4" radius as their smaller flanged counterparts. Flannery offers a variety of lengths for its Wide Flange Corners, including 7', 8', 9', and 10' lengths.

All of Flannery's Bullnose Corners have fastening holes along the flange to assist in their attachment to the gypsum board. The drywall must be kept back a 1/4" from the corner of the framing to allow for the curve of the bullnose corner. Bullnose corners provide a smooth transition from one wall to another, thus creating a softer look and feel versus standard square cornerbead. Install with nails, screws, construction staples, or adhesive. Consider using our Locking 3-way Corner Caps for adjoining corners, or our Bullnose Kerf around doors and windows.

All Flannery steel and vinyl trims are manufactured according to standard specifications for accessories of gypsum wallboard and gypsum veneer base. ASTM designation C 1047-85.
