Trim Purpose

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

Flannery is the only cornerbead manufacturer to offer Expanded Flange Bullnose Corners. Our Expanded Flange Bullnose has special taping holes that run the length of the trim, thus allowing taping compound and drywall mud to key through the drywall. Many trim installers prefer the larger flange, since it gives them a larger fastening surface.

When installing Flannery’s Expanded 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.
