3D™ Pro 3.5 Stretcher Bar • 1/2" Canvas Clearance

1/2" Canvas Clearance is the space between the Bar and the canvas. Generally speaking, more clearance reduces the risk of the canvas touching the wood and creating unsightly lines during painting. Our design provides the optimal clearance so as not to impact your painting, but still leaving enough wood to the maximize strength of the Stretcher Bar.

• Produces a 3.5" deep stretched canvas (Actual depth is slightly thinner)
• 1.25" wide Stretcher Bar
• All Bars have an exclusive groove on the inside perimeter of the frame to which cross braces and Diamond Corner Braces attach
• Solid Ponderosa Pine or Fir from the Pacific Northwest

Solid Wood is Archival - Finger Jointed Wood is Not

We only use Solid Wood to build our Stretcher Bars because a solid piece of wood will last indefinitely. When we speak of archival value, it's not just the paint you use and the quality of your canvas and ground, even the wood choices manufacturers make are part of the archival process.

The principal reason manufactures use finger jointed wood is reduce cost, not increase archival value. Wood constantly grows and shrinks when the environment becomes hotter, or colder, or more humid, or more dry. Because finger jointed wood is made-up of multiple and varied pieces of wood, with varying grain patterns and densities, they each absorb and shed moisture at varying rates, which works on the glue joints that hold them together, causing the wood to bow and the joints to eventually fail, and certainly not consistent with increasing the archival value of your artwork frame support.

As a manufacturer, we do our part to conserve as much wood as possible, and still provide a quality made product that will out-perform any other in the marketplace.

Sustainable Forests for Future Generations

Sustainable forestry practices go beyond just planting and harvesting trees. They also involve careful planning, monitoring, and management to ensure the long-term health and productivity of the forest. By using lumber from sustainably managed forests, we can support these important practices and help to ensure that our planet's forests remain healthy and productive for generations to come.

Specially Dried and Heat Treated Lumber

Our wood is handpicked from a curated group of environmentally responsible lumber mills in the Pacific Northwest. By adhering to our precise drying and heat-treatment standards, these mills produce lumber with nearly half the moisture you'd find in common home improvement outlets or lumber yards. This meticulous process not only enhances the wood's strength—minimizing risks of cracks, splits, or bends—but also elevates its dimensional stability. Such quality, despite its premium, is paramount in creating professional canvases designed to uphold the sanctity of your cherished art throughout the years.

31x118 is the Canvas Size Needed for this 21x108 Frame

Please note that you will need a canvas that is at least 10 Inches larger than the actual frame size to ensure proper stretching. This will provide ample material to stretch the canvas and attach it to the back of the frame. If you prefer to attach the canvas from the edge of the stretcher frame, you can reduce the size of your canvas by approximately 3/4" all the way around the frame. This will allow you to paint on the edge of the canvas and hang your artwork without needing a separate picture frame. And, if you ever need to remove the canvas from the frame and re-attach it, you'll have enough material to do that too.

Shadows cannot see themselves in the mirror of the sun. ♦ Paul Gauguin

Paul Gauguin's metaphorical insights often straddle the line between art and philosophy, and this statement is no exception. Through this poetic lens, Gauguin seems to highlight the inherent limitations of perception and understanding. Shadows, ephemeral and intangible, are by their very nature devoid of substance when exposed to the brilliance of the sun. Similarly, certain elements of our artistic endeavors remain elusive when directly confronted or overanalyzed.

Every artist knows the struggle of translating a vivid imagination onto canvas. Sometimes, the raw emotions or intricate visions we hold are best expressed not by direct illumination, but by the subtle interplay of light and darkness, the nuanced dance of what is revealed and what remains hidden. For us, it's a reminder that not every detail needs to be explicitly shown; sometimes, the most potent emotions are conveyed through implications and nuances.

As we immerse ourselves in our work, it's worth pondering the spaces between the overt and the subtle. The realms Gauguin alludes to—those areas untouched by the sun's direct light—are where true depth often resides. In our pursuit to bring life to our art, it's crucial to embrace both the brilliance of clear vision and the mystery of shadows. Only then can we hope to capture the full spectrum of human experience and artistic expression.
