⚡ At a Glance
- • Tension Control: Wedges expand stretcher corners to increase canvas tautness and reduce bounce
- • Best for: Artists and studios needing quick canvas maintenance without re-stretching
- • Not ideal for: Frames narrower or wider than 18 mm where wedge fit may be loose
Wooden wedges slot into inside corners to expand stretcher bars, creating more tension on slackened canvases. The pack contains 10 wedges, suitable for 18 mm frames with eight wedges recommended per frame.
Quickly Restore Canvas Tension - with wedge keys that expand stretcher corners
Wedges are driven into the triangular gaps at inside corners, forcing the stretcher rails apart and tightening the canvas surface. The mechanical expansion increases tension locally without needing to remove or re-staple the canvas.
Restore tautness in minutes rather than hours, making small repairs and tune-ups straightforward. Useful for touch-ups before exhibitions or photographing work.
Fits Standard Frames - with sizing matched to 18 mm stretcher bars
Wedges are sized to sit in the interior corners of 18 mm frames, providing a snug contact surface that transfers leverage to the rails. Eight wedges are typically required to treat all four corners effectively.
Guaranteed compatibility with 18 mm frames avoids guesswork when buying replacements. Makers of standard canvases can rely on consistent fit and predictable results.
Ready-to-Use Pack with Spares - with ten wedges included per pack
Each pack contains 10 wooden wedges, while eight wedges are normally needed for a single frame. The extra pieces act as spares for future adjustments or for treating multiple frames.
One pack covers one frame and leaves two spare wedges for later use, so studios can perform quick maintenance across several canvases. Handy for batch prepping work for shows or sales.
