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

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.

Our Ecosystem Depends on Healthy Forests

Forests play a vital role in our planet's ecosystem. They absorb carbon dioxide, filter air and water, and provide habitat for countless species of plants and animals. By using sustainably sourced lumber, we can help to protect these important ecosystems and ensure that they continue to provide these valuable services for generations to come.

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.

26x28 is the Canvas Size Needed for this 18x20 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.

To have the respect of such men as these gives any man an untouchable armor against the world. ♦ Robert Henri

Robert Henri, a prominent figure of the Ashcan School, was more than familiar with the weight that validation carries in an artist's life. His words highlight the profound impact of recognition, especially when it comes from those we deeply admire. In the realms of art, where subjectivity reigns supreme and criticism is ever-present, the acknowledgment from peers or mentors can fortify an artist's confidence and serve as a beacon during tumultuous times.

For artists, the path is often filled with both acclaim and rebuke. But when those whom we hold in high esteem recognize our endeavors, it provides a shield, an affirmation that our direction, however unorthodox or challenging, is valid. This recognition, however, shouldn't solely be a source of pride; it should also inspire us. As artists, we have the responsibility to support and uplift others, to be the beacon for those coming up behind us. In doing so, we not only enrich our own experiences but also fortify the collective strength and resilience of our community.
