The Masterpiece Monet Pro profile is 2.5cm - 1.3cm deep when stretched, and offers a full -1.3cm reveal between the bar face and canvas back. The revolutionary bracing system offers complete frame expandability and maintains tautness. No glue, staples or plastic components restrict the user from keying out corners or braces! Folded corners mean the selvage is uncut and sufficient for restretching on the same size frame. Cotton Carmel Portrait canvas offers an exceptionally fine finish for artists desiring a smooth, uniform surface texture. Carmel is ideal for portrait type paintings with a high degree of detail and provides an archival base.
