the first clip biasing the sash toward the first jamb away from the second jamb and the second clip biasing the sash toward the second jamb away from the first jamb to center the sash between the first jamb and the second jamb prior to the adhesive connector securing the outer face of the fixed sash to the frame as the fixed sash is moved toward the frame;

wherein each of the first clip and second clip includes a first leg pivotably received within the frame, a second leg extending from the first leg and including a tab having a point that pierces the frame, and a third leg extending from the second leg at an obtuse angle and a fourth leg extending from the third leg at an acute angle in a direction toward the first leg.
