A Picture Frame Rabbet serves a crucial role by holding the art, glass, and backing material. It is a groove or notch that framers cut into the back edge of the frame. This notch functions like a hidden shelf inside the frame's border. This shelf remains out of sight from the front but is vital for securing everything.
The depth of the rabbet is significant. It needs to accommodate all layers-the glass, matting, artwork, and backing board. A too shallow rabbet won't secure these components. It's width also requires careful consideration. It should snugly support the glass and other materials without allowing them to move.
Framers use specific tools to craft a Picture Frame Rabbet, ensuring it is straight and even. The process involves skillful cutting into the frame's material. After creating the rabbet, the framer places the glass, followed by the artwork, any matting, and then the backing board. Artists with canvases only will generally secure their artwork directly into the rabbet of a floater frame or allow a stem moulding to but up against the lip of the artwork. The rabbet plays a crucial role in keeping these layers flat and aligned.
In essence, the Picture Frame Rabbet is an essential part of a picture frame, acting as a hidden support to hold the art firmly in place. It's simple design is key to effective framing.
