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.

• Produces a 2.5" 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

Finger Jointed Wood is not meant for Stretcher Bars

Solid wood makes the most dependable Stretcher Bar, because one homogeneous wood member is going to behave similarly across the entire length of the Bar. Whereas, with finger-jointed wood is made-up of multiple pieces of wood, sometimes on the actual joint itself, presenting multiple points of failure which no one can control.

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 add or reduce value to your final painting. The fact is, you don't want problems, and finger joints only increase that risk of the wood falling apart in the future.

The glue used to bind finger joints is a water based adhesive and when that wood is exposed to high humidity environments, particularly with exterior walls, the glue joints can give-up. 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.

For the mind does not require filling like a bottle, but rather, like wood, it only requires kindling to create in it an impulse to think independently and an ardent desire for the truth. ♦ Plutarch

A prolific ancient philosopher, Plutarch offers a perspective on the nature of education and personal growth that is both timeless and profoundly relevant. Instead of viewing knowledge as a passive accumulation of facts or information, he champions the idea that true understanding arises from a fervent curiosity and an innate drive to seek out the truth.

In our realm of art, this insight is particularly poignant. Just as a piece of wood needs only a spark to ignite its potential, our creativity is set alight by inspiration, passion, and the inquisitive spirit. We don't simply absorb techniques, styles, or theories. Instead, we interact with them, challenge them, and adapt them to our unique visions. This dynamic process doesn't stem from a passive intake but from an active engagement with the world around us.

Embracing Plutarch's wisdom can serve as a guiding principle in our art careers. It reminds us that true creativity doesn't emerge from rote learning but from a burning desire to explore, innovate, and express our truths. As artists, we are encouraged to kindle that flame within, letting it guide our hands and hearts in the perpetual quest for genuine expression.
