Square Peg Manufacturing is proud to present its line of Bulnose corner block moulding. The majority of new homes being built today have rounded (bulnose) corners instead of crown molding (square) corners. A bulnose corner looks great but can cause a problem when applying base molding along the floor. This is where our corner blocks come in, fitting around the corner . . . making it very easy to apply straight base molding on each wall. So whatever kind of molding you're using, be it Anderson, Colonial, or Streamline, make sure you put a Square Peg bullnose block on the corner.
