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.

• Super strong 3D™ Pro K2™ Stretcher Bar is a very popular among contemporary artists whose painting will be displayed without a frame.
• For this 21x43 large size frame, the frame provides the ultimate foundation for your art with increased strength and stability
• Provides a 2.5" deep stretched canvas which makes a bold and commanding display
• 1-1/4" wide Stretcher Bars
• 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

Sustainably Managed Forests Inhale and Exhale

The world's forests are essential to human survival. Forests inhale carbon dioxide for the earth, and exhale oxygen essential for life. When we speak of the sustainable forest strategy of ensuring that more timber will exist in the same forest land than exists today, this is the only viable plan for the future of humanity. For this reason, we use only lumber from the sustainable forests of Oregon, Washington, and California, where there’s more standing timber today than last century!

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.

29x51 is the Canvas Size Needed for this 21x43 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.

From the heart of California, Masterpiece® has been weaving a legacy since 1965, curating the best Stretcher Bars North America has witnessed.

Patience serves as a protection against wrongs as clothes do against cold. ♦ Leonardo da Vinci

Leonardo da Vinci, one of the most diversely talented individuals in history, wasn't just a master of art, but also an observer of life and human nature. He lived in a time of political upheavals, power struggles, and intellectual revolutions. Yet, in the midst of such a turbulent age, he distinguished himself not just by his prodigious output, but by the depth of his thought.

For many artists, the path of creation is fraught with obstacles: criticism, doubt, and myriad external challenges. Just as the cold can be biting and relentless, so too can the world seem in its assessments and misunderstandings. But da Vinci offers us a shield: patience. With patience, we can endure, outlast, and ultimately prevail. Just as clothes protect us from the harshest elements, patience armors us against the precipitate judgments and transient opinions of others. Embracing this virtue, artists allow their work to mature, to evolve, and to reach its full potential, irrespective of immediate reactions.
