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

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.

24x40 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 24x40 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.

Sustainability in our Forests and our Communities

At Masterpiece®, we believe in responsible and sustainable business practices. That's why we only use lumber from sustainably managed forests in our products. By doing so, we can help to protect our planet's forests, reduce our environmental impact, and support the communities that depend on these valuable resources.

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.

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.

• Drum-tight stretch!
• Up to 50% tighter than other methods
• Balanced tension across the surface
• Uncut folded corners make it possible to remove and re-stretch canvas on the same size frame
• Usually the corner folds are on the long sides

Our unwavering commitment at Masterpiece® is to produce only the finest, which has made us the vanguard in the world of professional fine-art canvas. Explore our extensive range of surfaces and roll sizes to find the perfect fit for your next creation.

Every artist wants to be applauded. ♦ Jean-Jacques Rousseau

Jean-Jacques Rousseau, a prominent philosopher, writer, and composer of the 18th century, made significant contributions to music and literature, all the while wrestling with complex notions of self-worth and recognition. His personal challenges with acceptance and the nature of human validation characterized much of his writing. For artists, the echo of a viewer's admiration or a listener's applause often validates our long hours of work and countless moments of doubt. It's an affirmation that our creative voice is not just a whisper lost in the wind, but a resonating call felt by others.

The desire for recognition is universal, but in the art world, it holds particular poignancy. When we pour our emotions, experiences, and very souls into our work, it's only human to hope that our efforts touch someone, that they're seen and appreciated. Rousseau's sentiment isn't just about seeking praise; it's a profound understanding that our creations, an extension of ourselves, find purpose when they connect with others. That connection reminds us that in the vast tapestry of artistic expressions, our thread has its distinct and valuable hue.
