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

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

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 add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. 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.

40X48 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 40X48 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 - A Precious Natural Resource

The air that we breathe depends upon our healthy forests the world over. For this reason, we only use lumber from the sustainable forests of the Pacific Northwest, so we can guarantee that our nation's precious natural timber resources are available for future generations.

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

Oversize Box

This item is classified by UPS and Fedex as oversized, which might incur slightly higher shipping charges. To mitigate the shipping cost, we recommend ordering in quantities of 2 or 4 or more, and it travels safer too.

One of the most celebrated features about 3D™ Pro 3.5 canvases is the patently robust framing system that makes it possible to increase the tension in the middle of the canvas, where the tension is needed the most. Our well-made keyable bracing system supports the canvas indefinitely. Braces prevent the stretcher bar frame from bowing-in so the canvas stays tighter long-term.

It is better to have done something than to have been someone. ♦ Claude Monet

Claude Monet, the father of Impressionism, wasn't merely content with being a pioneer; he was obsessed with pushing boundaries, capturing fleeting moments, and redefining the way we perceive art and nature. Monet was no stranger to criticism and struggled in his early career, but he never let public opinion sway his dedication to his unique vision.

This sentiment encapsulates a profound truth. We, in our art careers, often grapple with the notion of identity and legacy. Do we want to be remembered for our titles, accolades, or the name we've carved out in the community? Or is it more crucial that our works and contributions tell the story of our passions, struggles, and triumphs? Monet encourages us to focus on the doing, on the creating, on leaving a tangible mark in the world rather than getting caught up in titles and recognition.

Our canvases, brushstrokes, and colors become the chronicles of our existence, and Monet's words urge us to ensure that these chronicles are rich, vibrant, and genuine. After all, in the grand tapestry of art history, it's the bold strokes, the revolutionary ideas, and the evocative pieces that endure. It's the deeds, not just the titles, that carve out a space in the annals of time.
