A drywall trim for protecting drywall can include a metal body having a seam with a longitudinal axis. The metal body can include wings or planar portions that extend from the seam in transverse directions relative to the longitudinal axis. The planar portions can be formed at an angle relative to each other. At least one of the planar portions can have an outer edge that is not parallel to the seam. Paper can be bonded to the metal body.

Drywall trim

High flow ember shield

A cornerbead for drywall construction having an elongated strip with a longitudinal nose bent at a substantially right angle and having a left side and a right side extending outwardly from the longitudinal arcuate nose; at least one raised portion extending the length of the left side; and at least one raised portion extending the length of the right side.

Grooved cornerbead

A high-flow ember shield building ventilator with a substantially trapezoidal outer frame portion with a long side, a short side, a substantially vertical front side and opposing angled sides; and a folded metal insert. The long side has a first long side end and a second long side end, the short side has a first short side end and a second short side end, the substantially vertical front side has a first substantially vertical front side end and a second substantially vertical front side end, the angled side has a first angled side end and a second angled side end and the folded metal insert is between the first angled side end and the second angled side end.

High-flow ember shield building ventilator

A cornerbead for drywall construction according to one embodiment having an elongated strip bent at a substantially right angle to form an upper portion having an upper edge and a lower portion having a lower edge; and at least two triangular cut out projections along the upper edge and at least two triangular cut out projections along the lower edge.
