Welcome to dickblick
Prevent the bending, warping, and twisting caused by humidity or dryness with Best's unique museum-quality Pro-Bar System.
Stable and strong, this framing system is designed with a full 1/2" relief between the canvas and stretcher bars to prevent any ghost impressions on your stretched canvas. The combination of wood and recycled aluminum creates a stronger, more rigid support — great for large-format works.
The stretcher bars are made of kiln-dried pine, which is attached to a specially milled 3/32" aluminum bar. The pine bar offers a smooth, rounded edge and a solid surface for stapling or tacking. The warp-resistant bars measure 1-3/8" thick and 1-7/8" wide.
Best Cross Braces are recommended for frames larger than 36". Please note that even though the cross braces fit snuggly against the stretcher bars, they must be attached to the frame with cross brace brackets. Two FREE brackets are included with every cross brace purchase.
Best Pro-Bar Steel Corners are required to complete the system. Use four corners per frame, or eight corners for optimum strength. As an additional option for quick, easy canvas adjustment, use Best Corner Keys.
The Best Pro-Bar System is made in the USA.

Best Corner Keys, Pack of 4

Easy to assemble, will not warp, impossible to assemble and not come out perfectly square. Would recommend to anyone. I use these stretcher bars for all my large commission pieces.
Pro Bars Rock!
from Sarasota, FL
I bought a set of these Pro Bars when I was working on a heavy linen substrate. The piece was going to travel to an important show, and I needed a guarantee, through different weather changes and handlers, that my painting was not going to warp. I was very impressed when I received my package of Pro Bars. And the added comfort was knowing I could adjust and square the art stretched on these pro-bars to an exact dimension. This is the finest stretcher I have used.

A little tough, but worth the effort!
from Allentown, PA
Putting it together was a bit of a challenge for me because the holes that the screws are supposed to go into were too tight. I kept struggling with it and stripped a few screws, but then I called the customer service at Best Artist's Materials and they were extremely helpful and friendly. All's well that ends well and now my frame is excellent and I am a better carpenter from the experience.
Consistently great product!
from Philadelphia, PA
Stretcher bars are always straight and fit together easily. It solves the warping problem nicely. I stretch heavy linen on large stretcher bars so it's nice to be able to tighten with the simple turn of the corner nuts.
Excellent - Well worth the cost!
from Lincoln, CA
Perfect, no-sag stretcher, for large 7'x 5' canvas.
I needed stretchers for an 8x10'painting. Never put one that large together and was worried about warping. The stretchers and braces arrived in good condition, fit together perfectly, canvas stretched and primed with no warping. Easy to put together and take apart as the painting has to be rolled and shipped. Arrived on the day they were supposed to arrive.

Difficult to put together
from Detroit, MI
I wanted a strong structure for large-scale paintings, and having had aluminum stretchers in the past I thought this would be a good product to try that was still strong but lighter weight. Unfortunately the system is nearly impossible to put together. The pre-drilled holes for the corner braces were not large enough, and I ended up stripping five of the ten (low-grade) screws. Also, there were no pre-drilled holes for the cross-braces, so I had to measure each one and pre-drill into the metal (hopefully you have metal drill bits!). I have yet to complete putting it all together.
Merchant response: We're sorry to learn about the difficulties you experienced with the Best Pro Bar System. Since there are so many possible configurations for cross bracing, the stretcher bars in this line are not pre-drilled. If you would like any further assistance with this product, please don't hesitate to reach out to our Product Information team. They can be reached at 1-800-933-2542 weekdays 8am to 5:30pm CST or firstname.lastname@example.org, and they're happy to help!
The best stretchers. Always square
Best Aluminum Stretcher Bars are the straightest, most scale-able bar that meets the needs of artists who work small or very large. They are easy to assemble and allow for both traditional stretching where the canvas is side-stapled, as well as a gallery-style stretching, where the canvas is back stapled. The corners, keys and cross-braces give artists the most professional canvas for their fine painting and artwork.
