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

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.

15x20 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
• No Brace Required for this size
• To increase canvas tension, remove any staples in the corners and tap all of the expansion keys further into their respective slots, then tension and re-staple the canvas in the corners

Tree Replanting - Essential to Sustainably Managed Forests

Harvesting timber provides humans with an essential natural resource, but replanting trees at a rate higher than a harvest is a key component in humanity's effort to guarantee a healthy forest for the future. Increasing our number of trees is just as essential to our economy, as the harvest itself, which is why we select only timber harvested from responsibly managed forests.

MuseumWrap™ Stretching Technique

With more than a half a century of American engineering, Masterpiece® designs and builds its own proprietary stretching equipment that enables us to produce the finest and most tightly-stretched canvas on the market.

• Usually the corner folds are on the long sides

3D™ Pro 2.5 Professional canvases are built one-by-one and stretched using our proprietary stretching process called, MuseumWrap™, which relies on in-house custom-built pneumatic machinery that delivers consistently drum-tight stretched canvas, balanced tension across the canvas surface, neatly folded uncut corners, and paintable edges. It is the absolute best way to stretch a canvas.

And since geometry is the right foundation of all painting, I have decided to teach its rudiments and principles to all youngsters eager for art. ♦ Albrecht Dürer

Albrecht Dürer, a master of the Northern Renaissance, wasn't merely an artist in the traditional sense. He was a thinker, an innovator, and above all, a student of the world. His appreciation for geometry was more than academic; he believed it held the keys to understanding the structures and harmonies of the universe.

For Dürer, the intersection of art and science was clear. Just as a musician requires an understanding of acoustics and scales, an artist must recognize the mathematical relationships that define our world. By teaching the young the principles of geometry, he aimed to equip them with the tools to see the world more deeply, to comprehend the hidden relationships that bring a scene to life. As artists, it's this deeper understanding that allows us to elevate our work, to move beyond mere representation and touch the very soul of our subject. Through understanding comes the ability to innovate, and it's this spirit of innovation that we should carry with us in every brushstroke, every line, and every form we create.
