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.

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.

Forests need People, and People Need Forests

The concept of sustainability presupposes a comprehensive engagement of individuals in the art and science of forest stewardship, both in the present and for the well-being of generations to come. Humanity undoubtedly extracts wood from forests to supplement our needs, but they also play a crucial role in bestowing diligent care upon these ecosystems. This stewardship encompasses not only the responsible harvesting of forest resources but also extends to the safeguarding of clean water sources, the preservation of wildlife and their native habitats, and the mitigation of potential threats like erosion, fires, and diseases that could otherwise lead to untimely degradation of these precious woodlands.

Masterpiece® uses only lumber harvested from responsibly and sustainably managed timberlands.

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.

53x68 is the Canvas Size Needed for this 45x60 Frame

Please note that you will need a canvas that is at least 8 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.

Every true work of art has as much reason for being as the earth and the sun. ♦ George Inness

George Inness, renowned for his evocative landscapes, believed in the inherent value and purpose of every genuine piece of art. Much like the earth serves as the cradle of life and the sun nourishes it, a true work of art has a fundamental place in the fabric of existence.

In the vast universe of creation, artists weave narratives, emotions, and perspectives into their work, each piece becoming a celestial body in its own right. Just as the earth and sun are essential in the cosmic ballet, artworks light up our human experience, providing warmth, inspiration, and understanding. The creations we bring forth are not just expressions of our individual selves but are intrinsic to the collective human narrative. Inness challenges us to see that our contributions, as artists, are as vital and purposeful as the very celestial bodies that govern our world.
