About the AL-40

The AL-40 features a 40mm (1-½") depth, giving artists, galleries, and conservators a bold, rigid and durable frame designed for canvases up to 90" in dimension.

• Strong yet lightweight, professional-grade corrosion resistant aluminum

• Excellent stability in challenging environments with variable temperature and moisture levels

• Ideal for small and large canvases, institutional installs, and conservation

• Large 1/2" (12 mm) setback between canvas and braces helps to avoid ghosting

• Preferred by artists who want a substantial profile for visual impact

• Perfect for museum-quality presentation or works that travel

• Integrated Tool-free canvas tensioning.... at all times
