Bullnose Door and Window Trim
If you have specified or installed Bullnose Cornerbead on your project already, then you may want to consider using Flannery's Bullnose Door & Window Trim to complete the "rounded corner" style of design. Our Bullnose Door & Window Trim allows you to have a clean and smooth Bullnose transition between drywall and your doors or windows. The Bullnose Door & Window Trim comes in both a 1/2" or 5/8" width and is slid over the edge of the drywall. While the fastening flange has a tapeable edge for compound joint, the other flange tucks in between the drywall and the framing. We offer both the 1/2" and 5/8" Bullnose Door & Window Trim in a variety of lengths including 7', 8', 9', and 10'. You have invested in Bullnose Corners for that extraordinary look, now complete it by installing Flannery's Bullnose Door and Window Trim around all of your doors and windows.
All of Flannery's Bullnose Trims have fastening holes along the flange to assist in their attachment to the gypsum board. Install with nails, screws, construction staples, or adhesive. When ordering this product please specify whether you need our 1/2" or 5/8" wide trim. If the Bullnose Door & Window Trim is not what your looking for, check out Flannery's Bullnose Kerf trim.
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.
