48x112 3D Professional 2.5" Deep K2 Stretcher Frame Kit

True 7:3 Extended Domino Proportion - 48x112 Size

This 48x112 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.

No Finger Joints!

Solid Wood is far superior to finger jointed wood, which is many small pieces glued together, each with varying grain densities that absorb and shed moisture at varying rates, expanding and contracting non-uniformly as environmental conditions change, and causing the wood to bow and the finger joints to eventually fail.

A single homogeneous kiln-dried solid wood Stretcher Bar outperforms and outlasts a finger jointed Bar whose sole purpose is to save the manufacturer cost, not contribute to the archival value of artwork intended to last a millennium. 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

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.

56x120 is the Canvas Size Needed for this 48x112 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.

Rooted in California and flourishing since 1965, Masterpiece® takes pride in its family-led legacy of crafting North America's premier Stretcher Bars.

The whole is more than the sum of its parts. ♦ Peter Paul Rubens

Peter Paul Rubens, the Flemish Baroque painter known for his extravagant compositions and masterful use of color, shared this profound insight into the essence of art. Born in 1577, Rubens' artistic legacy is characterized by his ability to create harmonious and dynamic compositions that transcend mere representation. His quote invites us, as artists, to explore the deeper layers of our craft and discover the magic that emerges when individual elements come together to form a cohesive whole.

Rubens was not only a gifted painter but also a diplomat and scholar. His vast knowledge and appreciation of classical art and philosophy greatly influenced his work. He understood that a painting's impact is not solely determined by the technical prowess of its parts but by the collective energy and synergy they generate. In a world where we often focus on perfecting individual brushstrokes or color palettes, Rubens reminds us to step back and view our creations as a unified narrative, where every stroke and hue contributes to a greater, transcendent whole.

As artists, we can draw inspiration from Rubens' holistic perspective. It encourages us to see our work as more than the sum of our efforts, to seek the hidden connections and narratives that emerge when we embrace the entirety of our creative process. In doing so, we can tap into the profound and transformative power of art, where the whole truly becomes greater than the sum of its parts.
