45x105 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 7:3 Extended Domino Proportion - 45x105 Size

This 45x105 is a unique Masterpiece size and 7:3 Extended Domino aspect ratio.

The 7:3 aspect ratio brings a bold and dramatic horizontal stretch, perfect for wide compositions that need to feel expansive and open. This format pulls the eye across the canvas, making it ideal for landscapes, cityscapes, or any scene where horizontal flow is essential. The narrow vertical space adds a layer of complexity, requiring careful use of vertical elements to maintain balance without overwhelming the composition.

There’s a natural tension in this ratio. The wide format invites exploration of the edges, creating a sense of openness, while the limited height keeps the scene intimate and controlled. It’s a format that encourages you to emphasize sweeping gestures, long vistas, or minimalist abstractions. It's great for conveying motion, distance, or the vastness of a scene, all within a strikingly sleek frame.

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.

• 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.

Sustainable Environment Promotes a Sustainable Economy

The use of lumber from sustainably managed forests is not only environmentally responsible, it also helps to support the economy and preserve jobs in the forestry industry. By choosing products made with sustainably sourced lumber, consumers can help to ensure that these industries remain strong and sustainable for years 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.

53x113 is the Canvas Size Needed for this 45x105 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.

In order to change artistic creation it is first necessary to change the spectator. ♦ Robert Delaunay

Diving into the sentiments of Robert Delaunay, it's evident that he recognized the symbiotic relationship between art and its audience. The canvas is not a mere playground for the artist; it's also a mirror reflecting the expectations, desires, and biases of those who gaze upon it. The perspective of the spectator, in many ways, shapes the art that emerges, leading Delaunay to the conclusion that evolution in art is intrinsically tied to the transformation of its audience.

It is through this lens that we can understand the imperative of cultivating a discerning audience. As artists, while our task is to push boundaries, to challenge conventions, it is equally vital to encourage our audience to evolve in their understanding and appreciation. This evolution fosters an environment ripe for innovation. When we and our spectators grow in tandem, the horizons of creativity expand, ushering in eras of groundbreaking artistic expressions.
