Precisely control canvas tension without restretching the entire frame
Precise tension control matters when canvas sags from humidity or heavy paint application. Best's corner key system lets you restore tautness without removing the canvas from stretchers, just turn the center nut to expand the corner incrementally. This mechanical approach delivers more control than traditional wooden wedges, which can split stretchers or create uneven tension across the canvas surface.
Each key fits into standard stretcher bar corners and adjusts independently, allowing you to address specific problem areas rather than forcing uniform expansion. The design distributes pressure evenly through the joint, maintaining structural integrity even under aggressive tightening. Metal construction ensures the keys won't compress or deform over time like wooden alternatives.
The kit includes four keys, one per corner, so you can restore an entire painting in a single session. Particularly valuable for large canvases prone to seasonal slack, or when building up thick impasto layers that add weight over time. Keep a set in your studio for maintenance work on stretched canvases that develop waves or loose spots between major projects.
