Corner Key is a small wedge or block of board, timber or plastic, inserted into the slotted inside corners of a canvas stretcher frame to prevent or adjust sagging.

Use[edit]

Sometimes called a tension key, the piece is tapped in to expand the stretcher bars slightly, tensioning the canvas. The keys can be used to re-tighten the canvas as it relaxes naturally over time. Tightening keys are commonly made in plastic or wood, and are commonly known as corner keys or corner wedges.

Types[edit]

Corner Keys or corner wedges come in various forms. Most wedges are available for a single size stretcher bar, making framers and artist hold various sizes in stock. A product called "wedgee" eliminates the need to hold many types of corner keys in stock as the wedgee has a male / female profile which allows them to be pressed together to fit most corner cut outs.
