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.

Selective Harvesting in our Sustainable Forests

Intelligent selective harvesting of timber is an ecological method to replace the natural occurrences of forest fires and disease and landslides that can devastate forests. This is all part of the process of sustainable forest management to which we subscribe when we choose which lumber we use in our products.

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.

28x67 is the Canvas Size Needed for this 18x57 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.

There's a sketch at every turn. ♦ Joseph Mallord William Turner

Joseph Mallord William Turner, known for his expressive landscapes and masterful use of light, found inspiration in the ever-changing vistas around him. Whether a turbulent sea, a tranquil countryside, or the hustle and bustle of a city street, Turner saw potential artistry in every corner of existence. His passion for capturing moments, whether grand or simple, was a testament to his belief that life itself is an ever-unfolding canvas.

Artists, in our ceaseless quest for inspiration, can take heart from Turner's philosophy. Every shadow on a wall, every gleam of sunlight through leaves, every smile exchanged between strangers holds the potential for creation. It's a call to be observant, to be ever-ready, and to understand that the universe provides us with endless opportunities to interpret, reimagine, and create. As we walk our path, we're surrounded by countless moments, waiting to be immortalized by our art.
