68 Inch 3D Pro K3 Stretcher Bar 3-1/2" Deep #K3-68

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

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.

Sustainably Managed Forests

We use lumber grown in the sustainable forests of the Oregon, Washington, and California, where thereÕs more standing timber today than last century! Our forests purify the air, provide oxygen, and reduce global warming. More trees are needed on this planet, not fewer. Therefore, we use lumber grown in responsibly managed forests, so future generations can benefit from our collective responsible actions today.

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 16x68 frame size, which happens to be a custom proportion, your canvas should be about 10 x 78. 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.

Art in nature is rhythmic and has a horror of constraint. ♦ Robert Delaunay

Delving into Delaunay's perspective, one can't help but marvel at his profound understanding of the universe's essence. To him, art wasn't just about brushstrokes on a canvas or sculptures in a gallery; it was the very fabric of the natural world. This belief was not born in isolation. Delaunay's own encounters with the vibrant play of color and light were deeply intertwined with this view.

Artists often turn to nature for inspiration, not just for its aesthetic beauty but for its inherent, unbridled freedom. Nature flourishes in its rhythm, from the ebb and flow of tides to the shifting of seasons. This rhythm is neither forced nor constrained; it simply is. For artists, nature exemplifies the ideal state of creation, unhampered by external pressures and unfettered by artificial boundaries. We, too, in our creative pursuits, yearn for this freedom, understanding intrinsically that true artistry can't be shackled or limited.

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.
