Strainer Bar

Strainer Bar

Definition

A Strainer Bar is a wooden support frame used in picture framing to provide structure and stability to the artwork and the frame itself. Strainer bars are placed behind all art materials inside a picture frame and are often screwed into the frame to reinforce narrow or lightweight frames.

Function

• Adds rigidity and support to the picture frame.
• Prevents bowing or warping of narrow or large frames.
• Acts as a foundation for stretching canvas and mounting other materials.
• Ensures the art materials remain securely positioned within the frame.

Applications

• Canvas frames for stretched paintings.
• Frames where structural reinforcement is needed due to size or weight.
• Used in conjunction with other tools like canvas pliers and stretching tools.
