Jack Richeson Best Key Canvas Tightening System, 4-Pack

BEST Keys are the world's best system for tensioning your canvas. Installed on all 4 corners of the backside of your canvas, BEST Keys will make your canvas tight as a drum with the simple turning of the nuts with a wrench. Simply tighten each corner a bit, alternating back and forth, and continue until you are satisfied with the tension on the canvas. BEST Keys act to evenly expand the stretcher joint which in turn tightens the canvas surface. This simple innovation can saves hours and the cost of having your artwork restretched. Wrinkles disappear with just a few moments work. We recommend BEST keys be installed on all canvases to make sure your artwork's presentation remains wrinkle free during its long life.
