Welcome to dickblick
Prevent the bending, warping, and twisting that results from humidity or dryness with BEST’s unique museum-quality Pro-Bar System. Stable and strong, it’s designed so that the canvas is always a full half-inch from the stretcher bars to avoid ghosting on the canvas. The combination of wood and recycled aluminum also creates a stronger, more rigid support for painting on a large scale.
Only kiln-dried pine is used to make Pro-Bar stretcher bars, which is attached to a specially milled 3/32” aluminum bar. The pine bar offers a smooth, rounded edge and solid surface for stapling or tacking. Bars measure 1-1/2” thick x 1-7/8” wide. BEST Cross Braces are recommended for frames larger than 36".
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.
Note — If notching is needed, please enter directions on how you would like your cross braces notched in the "Special Instructions" box on the Delivery & Gift Details page during checkout.
Note — Once notched, cross braces are non-returnable.
Best Key Corner System, Pkg of 4
Use these key corners as an optional feature with the BEST Pro-Bar System, or with any other wooden stretcher bar for quick, easy canvas adjustment. They’re easily installed into the pre-drilled holes on the Pro-Bar stretcher bars using the eight included screws.

Consistently great product!
from Philadelphia, PA
Comments about Best Pro-Bar System:
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.
Bottom Line Yes, I would recommend this to a friend

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.
Bottom Line No, I would not recommend this to a friend
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
Good frame but could be great
The frame its well constructed however the crossbar's supports are poor, the plastic is aversge material and the screws are a total waste as 6 of the 18 I used in a 2 crossbar support frame were broken. You also need to drill (with a power tool) the holes in the aluminium for the cross bar's supports. It is a shame about these details because it feels like the frame' messure exactitudes are dismissed.I got a 63in X 35in frame

the best stretchers, the worst screws...
These are the best stretchers on the market for artists that are tired of having stretchers warp after paintings are finished. I use them for all medium to very large paintings. The thing that is impossible for me to understand is why they sell great stretchers, awesome corner expanders and well designed brace bars, why they include incredibly cheap screws with them. The screws twist in half every time, I'm not embellishing. It's like they're made out of that plastic for toys that just looks like metal. When you get the accessories to assemble the bars just throw away the screws and use quality metal screws from a hardware store. otherwise you'll spend a lot of time drilling out screw remnants from the predrilled hole.

need to buy the corner keys
from Bozeman, MT
they say the corner keys are optional, but without them, it is only the tension of the stretched canvas that holds everything together.

Very nice stretcher bars
By Kathy the cyclist
from Pittsburgh, PA
I had a commission for a very large piece. I feel very confident that my painting will not warp or become distorted in any way. This system goes together nicely, too. Excellent product!

Worth the money!
from New York City
I work with large canvases (at least 24" in each direction), so I'm always looking for ways to make my frames as sturdy as possible. I went from buying pre-made canvases to stretching my own when I was having difficulties finding canvases in the sizes that I needed. When I started stretching my own canvases, I ran into issues with being able to effectively secure cross braces to the stretcher bars. My solution was to try this stretcher bar system, and so far I'm very pleased.2 months ago I stretched a 30" by 50" frame using this stretch bar system. I did not use a cross brace. I didn't need to; the aluminum in these frames was so sturdy that there was no need (just like the product description states). I have had no issues with warping since I stretched the canvas. This stretcher bar system will save you money on cross braces and significantly reduce the amount of time it takes to stretch a canvas. Even with saving money on cross braces this is a little pricey, but I think it's worth it.
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.
