A strainer bar is a type of wooden or metal bar used to stretch and secure canvases for painting. It is part of a frame that holds the canvas tightly in place. The strainer bar is attached to the edges of the canvas, and the canvas is pulled over it and secured to create a smooth, tight surface. This ensures that the canvas stays stable and even during painting, preventing wrinkles and loosening. Strainer bars are commonly used by artists and in framing to prepare canvases for artwork.
