This set includes eight wooden canvas wedges, often referred to as stretcher keys or canvas keys. These small triangular pieces are essential for maintaining the tension of canvas on stretcher bars. Made from lightweight wood, they allow for easy adjustment and provide reliable support for stretched artwork. The wedges are designed to be inserted into the corners of the stretcher frame, helping to ensure that the canvas remains tight and wrinkle-free. Ideal for artists and framers alike, they are a must-have for anyone who works with canvas. The wood has a natural finish, exhibiting a light color that complements various frames.
