ABSTRACT:
A venting device for ventilating new masonry, stone, precast veneer, or the like. The device comprises a conduit having an elongated body with a body wall and a first open end and a second open end. The first open end has a circumferential structure defining an inward flange with an inward edge that defines the meeting point of the inward flange and the inside surface of the body wall. The second open end has a circumferential structure defining a bevel. A generally cylindrical cup-shaped screen has a screen bottom with a circumferential screen edge and an essentially cylindrical screen wall integrally bound to the screen bottom at the circumferential screen edge. The cup-shaped screen is slidably disposed through the beveled second open end and the elongated body of the conduit such that the circumferential screen edge essentially registers with the inward flange edge and a portion of the screen bottom flushes against the inward flange. A method for manufacturing a venting device comprising flanging the first open end of the conduit such that the first open has a circumferential structure defining an inward flange with an inward flange edge that defines the meeting point of the inward flange and the inside surface of the body wall. The second open end of the conduit is beveled such that the second open end has a circumferential structure defining a bevel. The method for manufacturing the venting additionally comprises sliding the generally cylindrical cupshaped screen through the beveled second open end and through the elongated body of the conduit until the screen is disposed against the inward flange such the circumferential screen edge essentially registers with the inward flange edge and a portion of the screen bottom flushes against the inward flange.
