• and
• (b) a second frame comprising:
• (i) a second hollow body having a second inner end and a second outer end said second inner end having a perimeter larger than the perimeter of said first inner end of said first hollow body;
• (ii) a second flange surrounding said second outer end, said second flange including second means for attachment to the forms;
• and
• (iii) at least one ridge disposed around at least a portion of the inside of said second hollow body, said at least one ridge being shaped to engage said at least one shoulder of said first frame as said second inner end of said second frame is telescoped over said first inner end of said first frame.

A foundation vent to be used when forming concrete with forms, said foundation vent comprising:

• (a) a first frame including a first rigid body having a plurality of first walls, a first inner end, and a first outer end, said first frame further including a first flange around a perimeter of said first outer end;
• (b) a second frame including a second rigid body having a plurality of second walls, a second inner end, and a second outer end, said second frame further including a second flange around a perimeter of said second outer end;
• (c) means for engaging said first frame with said second frame in a plurality of telescoping positions such that said foundation vent can be adjusted to match a thickness of the concrete;
• and
• (d) frangible means for removably attaching said first flange and said second flange to the forms.

A method for creating a foundation vent within a concrete foundation wall while forming the foundation wall with forms, comprising the steps of:

• (a) providing a vent structure having two frames that are adapted to interlock in a telescoping fashion to fit a plurality of foundation wall thicknesses, the frames including wall projections that interlock in a plurality of locations;
• (b) locking said vent structure to fit a desired thickness of the concrete foundation;
• (c) securing said vent structure in a desired location between the forms;
• (d) pouring concrete between the forms such that the concrete at least partially surrounds said vent structure;
• (e) allowing said concrete to cure;
• and
• (f) removing the forms, leaving said vent structure mounted within the foundation wall.
