Wide Flange Bullnose Corner

Trim Purpose

Specs, MSDS, and LEED Information for Flannery Trims & Products

Flannery’s Wide Flange Bullnose Corner 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. Bullnose corners provide a smooth transition from one wall to another, thus creating a softer look and feel versus standard square cornerbead.

When installing Flannery’s Wide Flange Bullnose Corner, the drywall must be kept back a 1/4″ from the corner of the framing to allow for the curve of the bullnose corner. 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.
