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.

45x60 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
• Two super strong 3/4" thick keyable braces and two cross braces (all 3.25" wide) provide the maximum possible support for this 45x60 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.

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

Requires Truck Delivery

This size will be shipped on an LTL freight truck, which is safe and reliable. Our shipping cost estimator cannot possibly contemplate all the cost factors with truck shipments, so once you place your order and before we do anything, we will review and inform you if your actual cost is higher or lower. Ordering larger quantities usually does not increase the freight cost, so you get a better value by ordering larger quantities.

Conditions that impact cost are extra large products, or if your delivery address is out-of-the-way, or in a school, university, church, hotel, shopping mall, or farm. Shipping to a business address lowers cost. Contact us with any questions.

The trucking company will contact you by phone, and arrange a 4 hour window for delivery, so be sure to pick-up strange numbers during the time of delivery. Someone must be present to receive and sign for this delivery; they will not just leave it at your door. We rarely have issues, but if you notice a problem, please document it on the delivery receipt before you sign it, and take photos.

We, at Masterpiece®, are creative engineers and craftsmen, artists at heart and in-practice, leading the nation in quality and innovation in the world of fine-art canvases. Our patented products and processes ensure an edge in performance, guaranteeing a canvas experience that's a class above the rest. Feel the finesse, see the difference, and let your artwork express your creative vision; while we provide you with a canvas of which you can be as equally proud.

Art must be the cultivation of beauty for beauty's own sake. ♦ Mary Cassatt

Mary Cassatt, a luminary in the realm of Impressionism, was not just a painter but a thinker, continuously exploring the essence and purpose of art. Her proclamation about art's true purpose serves as a reminder of the intrinsic value of beauty. In an era dominated by social conventions and standards, Cassatt's dedication to portraying genuine moments of life made her stand out. She captured the candid beauty of everyday scenes, often emphasizing the intimate bonds between mothers and children.

Today, artists find themselves amidst a whirlwind of trends, technological advancements, and the ever-present allure of commercial success. Yet, Cassatt's words beckon us to remember the heart of our passion. As artists, we must never lose sight of the pure joy of creation and the transformative power of beauty. Art isn't always about the message, the audience, or even the artist; sometimes, it's simply about celebrating beauty in its rawest form. By heeding Cassatt's wisdom, we can ensure that our creative endeavors remain true to the very essence of artistry, enriching not just our careers but our souls as well.

We hope you will be inspired by the wisdom, and our interpretation thereof, of Mary Cassatt, plus we made this unique little portrait to begin the creative process. Time to start your creative process!

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets.
