Flannery steel trims are manufactured according to standard specifications for accessories of gypsum wallboard and gypsum veneer base (ASTM designation C 1047-85).

Flannery’s Bullnose Door & Window Trim 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. Install with nails, screws, construction staples, or adhesive.
