Bullnose Kerf Trim
Flannery’s Bullnose Kerf is an excellent trim for transitioning from drywall to a door or window frame. It allows the installer to maintain the “rounded” look of a bullnose cornerbead around a door or window frame. The Bullnose Kerf trim has a 7/8″ fastening flange with a taping bead for easy finishing. The other flange on the Bullnose Kerf is a 3/16″ flange which is inserted into a notch that must be cut out of the door or window frame.
Flannery Bullnose Kerf Trims have the same 3/4″ radius as their smaller flanged counterparts. Flannery offers a variety of lengths for its Bullnose Kerf Trims, including 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. Flannery steel trims are manufactured according to standard specifications for accessories of gypsum wallboard and gypsum veneer base (ASTM designation C 1047-85).
**Please note that Flannery’s Steel Bullnose Trims are not stocked and must be ordered in minimum quantities of 40 boxes**
When installing Flannery’s Bullnose Kerf Trim, 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.
