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.

• 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 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.

Sustainability Promotes Social Well-Being

The forests of the world are a precious resource that must be protected for future generations. By using lumber from sustainably managed forests in our products, we can help to ensure that these valuable resources are preserved and protected. This is not only important for the environment, but also for the social and economic well-being of the communities that rely on these forests for their livelihoods.

25x28 is the Canvas Size Needed for this 15x18 Frame

Please note that you will need a canvas that is at least 10 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 block of stone has a statue inside it, and it is the task of the sculptor to discover it. ♦ Michelangelo

Michelangelo, a luminary of the Renaissance era, often marveled at the potential hidden within raw material. His belief that each block of stone concealed a form waiting to be revealed is a powerful metaphor for the artistic process. Like the sculptor, we artists confront our chosen mediums, whether it be a blank canvas, a lump of clay, or an empty stage, with the challenge of unearthing its inherent beauty.

It's a reflection of our deeper conviction that beauty and meaning are everywhere, even in the most unsuspecting places. With skill, patience, and vision, we chip away at what's extraneous, aiming to reveal the essence of our subject. The process is as much about understanding ourselves as it is about mastering our craft. Each choice, each subtraction, brings clarity, not only to the work at hand but to our own perceptions of the world. This sentiment reminds us of the immense power and responsibility we hold, guiding us to see the potential in everything and craft narratives that might otherwise remain hidden.
