40X50 3D Pro Sierra Canvas 3-1/2" #TH-4050

True 5:4 Photography Proportion - 40X50 Size

The 5:4 aspect ratio is common to both art and portrait photography, as it creates a visually pleasing format for the human figure and face. The balanced compositional format can help to create a sense of symmetry and harmony in your artwork. The 5:4 ratio has a familiar "feel", as it was commonly used in early computer monitors. Additionally, you might consider trying some relatively unknown sizes in this same proportion that we call Lost Sizes As an artist, you get the best of both worlds, because you still get to use the same aesthetically appealing 5:4 format and use rare or novel sizes that help make your art stand-out.

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.

40X50 3.5" Deep Edge Heavy Frame Offers Maximum Support!

• Drawing depicts the exact frame construction, not the proportion
• 3.5" Deep Edge K3 Heavy Stretcher Bars are precision machined with a unique double tongue-and-groove corner joint that provides rock-solid torsional rigidity that resists warping or twisting, which is an important benefit for such a deep edge canvas
• One super strong 3/4" thick keyable brace and one cross brace (all 3.25" wide) provide the maximum possible support for this 40X50 frame; Cross Braces are permanently installed in the frame, but canvas tension may be increased by tapping-in the keys or wedges that slightly expand the size of the frame
• The Stretcher Bars have an proprietary utility groove on the inside perimeter of the frame which is used to attach braces and other optional frame supports
• The Masterpiece braces feature an exclusive system that allows you to increase the tension to the middle of the frame, where the tension is needed the most; it's so unique it earned us a patent
• Our state-of-the-art cross braces attach the ends of the cross braces into the (grooved) sides of the braces, which creates a superior and robust system of interlocking cross braces
• To increase canvas tension: 1) remove any staples in the corners and those that retain the brace keys in the middle, 2) tap all of the expansion keys further into their respective slots, 3) tighten and re-staple the canvas in the corners

Canvas Tension is in Your Control

In dry climates or air conditioned environments, the lack of moisture in the air causes wood frames to shrink and the canvas fibers to narrow and elongate making the canvas more slack and resulting in a loss of canvas tension. In some instances, the canvas could have waves on the surface resulting in an unsightly viewing experience.

Our 3D™ Pro 3.5 professional frames provide the functionality for you to slightly expand the size of the frame in the corners and the middle of the canvas, thereby increasing canvas tension all across the surface. The difference between a loose canvas and a tight canvas is just 1/8" of an inch, so a small adjustment using our corner and brace keys makes an important difference in canvas tension.

• Helps to prevent waves that occur in a loose canvas
• Increase canvas tension by tapping-in the corner and brace keys
• True professional class canvases make it possible for you to adjust the canvas tension

Cross Braces Make it Tighter

A tightly stretched canvas on an un-braced frame overpowers the Stretcher Bars causing them to bow inward and thereby lose tension. Sometimes that bow can expose a space in picture frames.

When a canvas is stretched on a properly supported frame, the cross-braces prevent the Bars from bowing thereby achieving maximum canvas tension. To increase the canvas tension even more, simply tap the corner and brace keys further in their slots. Properly supported frames provide you with the control over the canvas tension of your canvas and painting.

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

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.

The true work of art is born from the artist: a mysterious, enigmatic, and mystical creation. ♦ Wassily Kandinsky

Wassily Kandinsky, often heralded as the pioneer of abstract art, ventured into realms of creativity that were, at the time, uncharted territories. His groundbreaking perspectives were not just about shapes, colors, or techniques; they explored the very soul of the artist and the intangible essence of creativity. For Kandinsky, art was not a mere replication of the external world; it was a deep dive into the internal cosmos, a journey into the mysteries of the self.

Every artist knows that the creative process is multifaceted. It's not just about mastering the medium or technique, but about delving deep within, tapping into emotions, memories, and experiences that often lie dormant. When we create, we are not just translating a vision onto a canvas, but revealing a part of our essence, sharing a fragment of our soul with the world. This profound connection between the artist and their work is what Kandinsky highlights, reminding us that the value of art is not just in its aesthetic appeal but in the depths from which it emerges.

As we face the canvas, we're not merely working with pigments and brushes; we're engaging in a dialogue with our innermost selves. Our creations, thus, become a reflection of our dreams, fears, joys, and sorrows. Kandinsky's perspective challenges us to embrace this mysticism inherent in the artistic process, understanding that true art isn't just about what's visible, but more importantly, about the unseen emotions, thoughts, and energies that breathe life into it.

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets.
