Short Flange Bullnose Corner

Trim Purpose

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

Flannery's Short Flange Bullnose has become the standard for bullnose corners in the drywall industry. We call it “Short Flange” because its 5/8″ nailing flange is the smallest nail flange of our different bullnose corners. 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 Short 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.
