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.

Selective Harvesting in our Sustainable Forests

Intelligent selective harvesting of timber is an ecological method to replace the natural occurrences of forest fires and disease and landslides that can devastate forests. This is all part of the process of sustainable forest management to which we subscribe when we choose which lumber we use in our products.

Specially Dried and Heat Treated Lumber

We source our wood from a select group of top-tier environmentally conscious lumber mills in the Pacific Northwest. These mills specially dry and heat-treat the lumber to our specifications, resulting in about half the moisture content compared to wood from typical home improvement centers or lumber yards. This process makes the wood stronger, reducing the likelihood of cracking, splitting, or warping. While the wood we use comes at a higher cost, it ensures a more dimensionally stable end product. This stability is crucial for crafting fine professional canvases that support your invaluable art over time.

52x118 is the Canvas Size Needed for this 42x108 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.

There is no art without contemplation. ♦ Robert Henri

Robert Henri, an influential American painter and teacher, stood at the intersection of Realism and Modernism. His work, characterized by its vibrant energy and deep humanism, was a testament to the introspective processes that birthed it. For Henri, art was never just about the mechanical act of painting; it was about the inner reflections that guided the hand. It was about the silent moments of rumination, the periods of doubt, the flashes of inspiration, and the depths of thought that precede every brushstroke.

Contemplation is the bedrock upon which the towers of creativity are built. It is not mere inaction; it's an active process of engaging with ideas, feelings, and the world around us. Just as Henri immersed himself in the cultural tapestry of the cities he lived in and sought deeper meanings in everyday life, we too harness the power of contemplation to give shape to the nebulous thoughts and emotions within us. Every blank canvas offers us a fresh start, a space where our contemplative insights find expression, where our introspections and musings take form and color. And just as Henri once said, it is this very act of contemplation that makes our art truly alive, connecting us with audiences across time and space.
