Auralex CornerFills Flat-cut Studiofoam Corner Strips

Where two wall panels or a panel and a bass trap meet at a corner, the raw edges leave a hard line and a spot the treatment does not quite cover. CornerFills are sections of flat-cut Studiofoam sized to run down that seam, closing the gap and rounding the transition instead of leaving an untreated corner.

They come in two depths: 2 in x 2 in x 24 in strips packed 36 to a box, or 4 in x 4 in x 24 in strips packed 9 to a box, both in the same Studiofoam colors as the rest of the corner-trap line.
