    摘要: A foundation vent (20) for use with concrete forms (31) is disclosed. The vent includes two frames that telescope together into a plurality of locking positions to allow the width of the vent to be changed to match the thickness of the concrete wall. The first frame (26) includes first walls (34) and a first flange (40). The first frame has a first inner end (36), and a first outer end (38). The first flange is disposed around a perimeter of the first outer end. The second frame (28) includes second walls (60) and a second flange (70). The second frame has a second inner end (66), and a second outer end (68). The second flange is disposed around a perimeter of the second outer end. A ridge (74) engages in channels (52, 58) defined by a plurality of shoulders (50, 54) disposed on the frames to allow the two frames to telescope together and to lock at various, predetermined widths. The ridge is disposed around a perimeter of the second inner end of the second frame. The ridge thus engages one of the channels. The foundation vent is used by locking the frames together to form the desired width, securing the vent between the concrete forms in a desired location, pouring the concrete between the forms around at least a portion of the vent. After the concrete cures, the forms are removed, tearing away breakaway portions on the flanges, leaving the foundation vent mounted in the concrete foundation.
