3D™ Pro 2.5 means a 2-1/2" deep canvas that is stretched using our MuseumWrap™ back-stapled method with folded corners. Our proprietary stretching process uses pneumatically controlled machines that we built to yield drum-tight tension.

Order Even Quantities for Optimal Shipping Protection
At Masterpiece®, we're committed to delivering high-quality products that meet your expectations. Our custom-made, heavy-duty boxes provide triple-strength protection, but we recommend ordering even quantities of the same size to optimize shipping protection. By packing the delicate parts of the canvas face-to-face, away from the exterior of the box, we can ensure that your canvas arrives in perfect condition. We will still do our utmost to protect your package, even if you order only one.

- 100% Belgian Linen 11.6 oz. per square yard
- Very Heavy Weight, Tight Weave, Coarse Texture
- Raw fabric blocks 95% of the light, which indicates how tight is the weave
- Warp and Weft: 31x33 yarns per square inch
- Linen has natural oils that prevent disintegration over time.

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.
- Produces a 2.5" 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

No Finger Joints!
Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.
A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. As a manufacturer, Masterpiece® does its part to conserve as much wood as possible, and still provide a quality product that will out-perform any other in the marketplace.

33x42 2.5" Deep Edge Heavy Frame Offers Maximum Support!
- Drawing depicts the exact frame construction, not the proportion
- 2.5" Deep Edge K2 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 33x42 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 2.5 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.

What is Sustainable Forestry?
To a forester, the term "sustainable" could mean exercising industry adopted forestry practices to maintain a forest indefinitely. To a logger, the process of proper care for the trees remaining after a harvest. To a landowner, their interest may lie in keeping their forest in the family. And to those of involved in the process of making and using wood-based art supplies, it can mean promoting and supporting an industry dedicated to the preservation of our precious natural resource. We can all do our part to care for our national forests.
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.

I thought I was learning to live; I was only learning to die.
♦ Leonardo da Vinci
Leonardo da Vinci, a true polymath, towered over the Renaissance with an insatiable curiosity that stretched across numerous disciplines—from art and anatomy to engineering and natural history. His quest for knowledge was relentless, with a thirst that seemed to know no bounds. Yet, amid all this fervor for understanding, he was acutely aware of the fragility and impermanence of life. Leonardo's words echo the stark realization that, even as we pursue growth and understanding, we are inherently marching towards our own mortality.
But the profundity of this statement lies not in its melancholy, but in the impetus it provides artists. Leonardo's life, replete with pioneering artworks, inventions, and treatises, serves as a testament to the possibilities that arise when we embrace our transience. Our time is finite, and thus, every moment spent creating, contemplating, and contributing becomes all the more precious. Leonardo's musings challenge us to channel the impermanence of life into our work, to encapsulate the fleeting beauty and transient emotions we experience. Through this, we can hope to achieve the immortal—leaving a legacy that endures long after we are gone.
We are innately drawn to the act of creation. We've channeled this drive to curate this inspiring quote and contex along with our own portrait we created of Leonardo da Vinci..our tribute to the timeless dance of creativity. Go paint!
