Solid wood stretcher bars, cross brace, keys, and hardware. That 1½-inch depth creates ½-inch relief between bar and canvas, enough clearance to prevent the wood from telegraphing through your painting surface while maintaining structural integrity under significant tension.

Masterpiece mills these bars from single pieces of sustainably harvested Oregon and California wood, eliminating the finger-joints that create weak points where tension concentrates. Solid construction resists warping and holds tight corners through repeated adjustments. The included cross brace mounts perpendicular to the stretchers, distributing stress across the frame rather than letting larger canvases bow at the center. Two brace keys let you fine-tune tension as canvas naturally relaxes after initial stretching or responds to humidity changes.

Build custom sizes for specific projects rather than adapting compositions to pre-stretched dimensions. The relief depth works well for traditional and contemporary framing, while solid wood construction means these frames stay square through multiple re-stretchings as you reuse quality canvas.
