We know you're thinking of a fluffy, long-eared animal that hops its way around when you see the word "rabbet," but one of those little cuties would be spelled "rabbit." When it comes to framing, a rabbet is the recess on the back inside edge of the frame into which your artwork fits. "Rabbet size" refers to the depth of this recess, and for most framing projects, any rabbet size is fine.Custom Frames & Ready-Made FramesThese frames have open rabbets, so they will work for almost any framing project.Metal FramesMost of our metal frames have enclosed rabbets. When you're framing a very thick piece - like a stretched canvas - in a metal frame, be sure to choose one with a rabbet that will accommodate the thickness of the piece.Canvas Floater FramesThe depth of your canvas should closely match the depth of your canvas floater.
