Shop NowQuote / Order FormSuperior Strength
Our frames are built from premium-grade wood and architectural-grade aluminum, providing the robust support your large-scale artwork needs.
Custom Fit
We create frames in any size, accurate to 1/16” (1mm) ensuring a perfect fit for your artwork, no matter how large or unique.
Easy Assembly
Designed for straightforward assembly, our frames come with clear instructions and all necessary hardware, making setup simple and quick.
Precision Construction
Meticulous engineering and craftsmanship guarantees straight and true frames, even at the largest sizes.
Sectional Designs
For practical and affordable shipping, all frames over 96” are created with splice joints, designed for easy assembly and strong support for the finished artwork.
Frames can also be designed to allow the stretched canvas to be folded, a feature which could be a lifesaver for getting a frame around a corner or into an elevator!
Adjustable Tension
Keyable stretchers are even more important when stretching a large canvas as it is often difficult to create adequate tension by hand. Keys allow incremental expansion of the joints, ensuring that delicate paint layers are not damaged over time by sagging canvas.
Heavy-Duty Wood Stretcher Bars
Our heavy-duty stretcher bars are made from laminated wood, ensuring they remain strong and straight even over long lengths.
These bars are designed to prevent warping and maintain canvas tension, ensuring the longevity and integrity of your artwork.

We can create fastening options to tile any number of canvases.
Gravity Bars for Mounting
We recommend gravity bars (a variation of French Cleats) for hanging large stretched canvases. We can supply custom gravity bars for your frame(s), providing a stable and secure method for hanging your stretched canvas in your studio or gallery.

(1) Laminated Heavy-Duty Stretcher Bars for Added Strength and Straightness
As many artists have discovered, it is very difficult to make a straight stretcher bar longer than 8 feet out of solid wood. The longer the bars, the more likely it is that the wood will bow or twist and make the stretcher frame unusable. We have found that the only reliable way to make long stretcher bars strong and straight is to laminate two or more lengths of wood together. Every heavy-duty bar we use in our large frames has been glued and set in clamped jigs to produce very strong, straight and stable stretcher components.
(2) Edge-Glued & Finger-Jointed Clear White Pine for Greater Stability
To further improve the structural stability of the stretchers, we use edge-glued, finger jointed clear white pine for our long, laminated stretcher bars. This type of wood is widely used in the window and door manufacturing industry where straight components are critical. Our edge-glued, finger jointed wood is made up of short lengths of clear pine which are finger jointed and glued together to produce very strong, straight and stable bars. The superior strength and straightness comes from the random grain patterns which counteract in each other any tendency to warp.
(3) Double/Triple Tongue & Groove Friction Joints for Stronger Corners
All of our heavy-duty stretchers have extra strong double (Heavy-Duty) or triple (Extra Heavy-Duty) tongue & groove friction-fit joints at the corners of the frame. This means that each corner of our large stretcher frames has four or even six fully keyable friction-fit connections.
(4) Heavy-Duty Cross-Braces for Maximum Support and Clearance
Our heavy-duty frames use 3/4” or even 1-1/8" x 3” pine braces, which provide excellent support for the stretchers while still allowing the required amount of clearance from the canvas.
(5) Fully Keyed Bars and Braces
Since large canvases are more prone to sagging over time, it is especially important to have the canvas supported by a stretcher frame which can be “keyed-out” to maintain the required tension. All of our large stretcher frames are made with keyable corner and brace joints.
(6) Splice-Jointed Sectional Designs for Ease of Shipping and Assembly
The only practical way to ship a large stretcher frame over 8 feet is to make the long bars and braces in shorter sections that are bolted together at assembly. We use flush mounted hex-head connector bolts for fastening all splice joints (where bar or brace lengths overlap).
(7) Folding Stretchers for Easy Transportation of Artwork
With our splice-jointed sectional frame designs, it can be possible to fold a large canvas in two or more panels without having to remove the canvas. This saves a considerable amount of time and effort in situations where large paintings must be moved to new locations or even just around corners within buildings.
(8) Space for a Protective Backing
All of our heavy-duty stretcher frames have inward slope on the back side which allows for installation of a protective backing, if desired. Backing can be critical to the longevity of a work of art as it makes a barrier or buffer to reduce the effects of cycling climatic changes and atmospheric pollutants, and to reduce the risk of damage caused by mishandling.
(9) Easy Assembly – Instructions and Hardware Provided
With each stretcher frame shipped, we include detailed instructions along with any hardware (bolts) required for assembly and "keying out" (adjusting) of the frame. Every frame is assembled in our shop before shipping and each joint and stretcher bar/brace component is labeled to facilitate easy reassembly. An extra large stretcher frame (10’ x 20’) typically would take about one hour to assemble.
(10) Use Gravity Bars for Proper Installation
Because of the increased weight and dimensions of large canvases, it is important to provide proper support to avoid damaging the artwork or the wall. Hanging the painting using gravity bars is an effective and simple way to accomplish this. The top halves of the gravity bars are typically fastened to the vertical or horizontal braces on the stretcher frame at a spacing of about 3-4 feet across the width of the frame. The bottom half of each gravity bar is fastened to the wall; the force of gravity holds the painting securely against the wall.
