Elite™ Professional 1.5" Deep B2 Bar • 1/2" Canvas Clearance
A Canvas Clearance of 1/2" 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.
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.

Sustainably Managed Forests Purify the Air
Our forests purify the air by filtering nearly 40% of the fossil fuel emissions humans create, and are critical to reducing global warming. More trees are needed on this planet, not fewer, for our own healthy human survival. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our responsible actions today.
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.

57x70 is the Canvas Size Needed for this 51x64 Frame
Please note that you will need a canvas that is at least 6 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.
Tight'n'Up™ Liquid Canvas Retensioner
One of our most appreciated products helps make your canvas tighter! Stretching a canvas tightly can be a challenge. Our Frame Kits include the Corner and Brace Keys that you will need to add tension, but Tight'n'Up™ Liquid Canvas Re-Tensioner is a way that you can use to add tension to the canvas without needed to use the keys. It canvas 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. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.

Time destroys the speculation of men, but it confirms the judgment of nature.
♦ Cicero
The writings of Cicero, the renowned Roman philosopher and orator, often examined the contrast between man-made constructs and the immutable laws of nature. This particular sentiment encapsulates the fleeting nature of human conjectures in the face of enduring natural truths. While human theories, predictions, and speculations can be proven wrong or become obsolete with time, nature's judgments stand unwavering, tested and ratified by the unyielding passage of time.
The artistic path can be riddled with fleeting trends, transient critiques, and the ever-changing tastes of audiences. Yet, akin to nature's steadfast truths, there are core principles and emotions in art that remain timeless. As we delve into our art careers, it's tempting to follow the siren call of contemporary speculation or to tailor our creations to what's momentarily popular. However, grounding our work in the authentic emotions, universal truths, and the intrinsic beauty found in nature ensures longevity and relevance. By anchoring our creations in such timeless tenets, we, in essence, align our work with the enduring judgment of nature, granting it a permanence that transcends the ebb and flow of societal speculations.
Creativity is the heart of what we both do. So we've curated this empowering quote and some background. And, in our own act of creation, we provide this unique portrayal we made of Cicero.
