7236 Corner Keys for Stretcher Bars pack 4

Keeping a canvas on stretcher frames tensioned and rigid becomes more challenging as they get bigger. These Corner Keys are fixed with screws into each corner and help deal with both issues.

Made of steel, they can be adjusted with fingers and tightened with a 13mm spanner. Turning the nuts lengthens the key, increasing the tension in the canvas.

Corner Keys are 117mm closed and 11mm diameter. Screw holes are 4.2mm. 3.9mm x 18mm screws are included. Steel, zinc plated. Made in Brazil.

Great for larger frames and also when renovating older canvases.
