Canvas Tightening Keys or Wedges are the eight (8) wooden wedges you will commonly see on the back corners of paintings, or artist canvases that are mounted onto wooden stretcher bars. Tightening keys are used to tighten both new and old artist canvases. New canvases need to be tightened, and old canvases can become loose over time and will need to be made more taut with corner keys to prevent damage. Tightening keys are essential components for the maintainance of valuable new and vintage paintings on canvas. How Are Tightening Keys Used? Two (2) keys are gently tapped into the two (2) slots found in each corner on the back of oil paintings on canvas. Some professionals will use a small carpenter's "finish hammer" to tap the keys into the slots. Other experts will place a small block of wood on the outside edge of the tightening key then gently tap the keys into place. Equal pressure should be used with each key into each slot to prevent future warping of the stretcher bars. Upon insertion of the keys, care is taken not to apply too much pressure to the keys so as to make the canvases too tight, possibly causing the canvas to rip or tear.
