21 Inch 3D Pro K3 Stretcher Bar 3-1/2" Deep #K3-21

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

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.

By doing so, we can help to protect our planet's forests, reduce our environmental impact, and support the communities that depend on these valuable resources.

Canvas Size Needed for this Stretcher Bar

Most artists will stretch the canvas and attach the staples or tacks onto the back side of the frame. Doing so allows you to paint on the edge and hang your art without needed a picture frame. Generally speaking, you should allow 10 Inches of canvas beyond the size of your frame.

For example, if you were to stretch a 12x21 frame size, which happens to be a Paper Size, your canvas should be about 10 x 31. This allows you ample room to stretch and attach the canvas on the back. Should you ever need to remove the canvas from the frame and re-attach it, it still serves that purpose too. Should you want to attach the canvas from the edge of the stretcher frame, then you can reduce the size of your canvas about 3/4" all the way around the frame.

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

We are all of us more or less echoes, repeating involuntarily the virtues, the defects, the movements, and the characters of those among whom we live. ♦ George Inness

George Inness, celebrated for his evocative landscapes, touched on a profound truth about human nature with this statement. The concept of echoing - of being shaped by our environment and those we encounter - is universal. Just as a landscape mirrors the changing seasons and the passage of time, so too do we mirror the influences of our surroundings.

This concept is especially relevant. We often draw inspiration from our mentors, our peers, and the world around us, channeling those influences into our work. It's as if the brushstrokes on our canvas reflect not just our own thoughts and emotions, but the collective spirit of those who've touched our lives. Yet, in that echoing, there lies the potential for originality. As we process and reinterpret these influences, we find our unique voice, making art that is both a reflection of our world and a testament to our individual perspective within it.

Tight'n'Up™ Liquid Canvas Retensioner

One of our most celebrated products helps make your canvas tighter! Assembling Stretcher Bars and Stretching your own canvas can present some challenges. While your canvas may seem tightly stretched, the tension may vary from staple to staple creating lines of tension across the canvas in a grid like pattern. The trick is to maintain balanced tension across the canvas.

Tight'n'Up™ Liquid Canvas Re-Tensioner is a great way to redistribute the tension in a canvas across that grid-like pattern of tension as well as increase the tension on the entire canvas. While you can can add tension by keying-out the corners of the frame, it may produce an hour-glass effect by expanding the frame in the corners, and not the center.

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. Recommended for acrylic primed cotton or linen canvas. We do not recommend it for oil primed canvas because there are simply too many different types of oil primed canvas, but used conservatively at your own risk, it will tension any canvas.
