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.

• Produces a 3.5" 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

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.

Art is the bridge between imagination and reality. ♦ Pierre-Auguste Renoir

A leading figure in the Impressionist movement, Pierre-Auguste Renoir was distinguished by his ability to capture the luminosity of the world around him. From vibrant landscapes to intimate portraits, his work is a testament to the profound connection between an artist's inner visions and the tangible world. His perspective on art, as a bridge, provides insight into the very nature of the creative process.

For us, the blank canvas or untouched clay is not just a material but a realm of endless possibilities. Every stroke, shade, or sculpted form is a step toward bringing our abstract thoughts, dreams, and feelings to life. Renoir's belief resonates with the core of our artistry: the act of creating is not just a reproduction of reality but an interpretation, a dialogue between our deepest selves and the universe. By channeling our imagination through our work, we offer the world a glimpse into our souls and make the intangible tangible.

Tight'n'Up™ Liquid Canvas Retensioner

While all of our Masterpiece® Pro canvases are stretched very tightly and our frames have a built-in method to increase tension, we have another method to add canvas tension. Tight'n'Up™ Liquid Canvas Retensioner (sold separately) can be sprayed on the back of a canvas to repair most canvas tension issues.

With Tight'n'Up™, you can add tension to just a small area, or a large area. Simply spray it lightly on the back and brush it into the canvas, and within seconds, your canvas becomes tighter and stays tighter. The more you use, the tighter it gets.
