39x42 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 14:13 Near Square Proportion - 39x42 Size

The 14:13 aspect ratio is one of our intriguing near square proportions, which offers subtle asymmetry. Unlike a perfect square, which can sometimes feel static, a near-square ratio like 14:13 provides a slight horizontal or vertical stretch that introduces just enough imbalance to make compositions feel dynamic while still being contained and compact. Create an unusual tension between symmetry and asymmetry. This subtle variation in the dimensions might work well for portraits, still life, or minimalist compositions, where balance and proportion are important but don’t need the formality of a perfect square.

3D™ Pro 2.5 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.

• 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 Ensure More Wood for Communities

Using lumber from sustainably managed forests is not only the responsible thing to do, it's also a way to ensure that the wood products we rely on continue to be available in the future. By supporting sustainable forestry practices, we can help to ensure a steady supply of wood products while also protecting the environment and supporting local communities.

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.

47x50 is the Canvas Size Needed for this 39x42 Frame

Please note that you will need a canvas that is at least 8 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.

Art is the bridge between imagination and reality. ♦ Pierre-Auguste Renoir

A leading figure in the Impressionist movement, Pierre-Auguste Renoir was distinguished by his ability to capture the luminosity of the world around him. From vibrant landscapes to intimate portraits, his work is a testament to the profound connection between an artist's inner visions and the tangible world. His perspective on art, as a bridge, provides insight into the very nature of the creative process.

For us, the blank canvas or untouched clay is not just a material but a realm of endless possibilities. Every stroke, shade, or sculpted form is a step toward bringing our abstract thoughts, dreams, and feelings to life. Renoir's belief resonates with the core of our artistry: the act of creating is not just a reproduction of reality but an interpretation, a dialogue between our deepest selves and the universe. By channeling our imagination through our work, we offer the world a glimpse into our souls and make the intangible tangible.
