Stretcher or Strainer

We offer both expandable stretchers and fixed strainers, as both are very useful supports depending on the application and desires of the particular artist.

DaVinci Stretchers

Our premium custom stretched canvas and stretcher bar kits are among the best found anywhere, utilizing our proprietary DaVinci Stretcher Bar System, our specially engineered auto-squaring and precise-tensioning corner joints and on our super-straight T-Bars, which are coated with shellac to shield the archival canvas from wood acids. After stretching your canvas, if you desire it to be more taut, forget reaching for a hammer to drive crude keys into the corners like a caveman! The DaVinci corners utilize a cam-based tensioner coupled with a numbered dial, so you simply tighten each corner and bracing ends using a common screwdriver - easy, precise and risk-free.


Our premium strainers incorporate hefty hardwood dowels to provide a solid joint at each corner and a strong interface with each cross brace, preventing any twisting or rolling from the force of the tensioned canvas.


Bar Profile

For all of our custom stretched canvas, we utilize our own proprietary T-Bar design based on the concept of opposing forces. Since the T-Bar is made up of two parts, where the grain of one differs and perhaps runs exactly opposite the other, any warping tendencies are either greatly decreased or virtually eliminated. This provides greater stability than bars constructed from a single piece of wood. As the outer face bar is perpendicular to the rib, it provides support, and an opposing force against any tendencies for warping.

Also, one end of each of our T-Bar faces are notched at just the right angle so that the canvas fold at the corner is allowed to be embedded into the bar which allows for a clean and flush finish. This Clean Corner feature is built into all of our stretched canvases and is also available for free on our stretcher bar sets if desired.


This stretcher bar is low-profile, meant for smaller, framed paintings. However, it is not stapled on the edge as many canvases are with this width. Our Museum series canvases are gallery-wrapped so it could painted along the edge and hung without a frame. This narrow profile is actually preferred by many artist, over the deeper profiles.






This is the typical depth for gallery-wrapped canvases. It displays rather well on its own with no additional framing, especially when the edge is painted black. However, this size also works very well with float frames for a more sophisticated look.

For larger canvases, the extra 1/2" depth provided by our Gallery Plus profile gives more strength and a beefier look, without adding excessive weight.








Bigger canvases need deeper bars, both for aesthetics and better strength integrity. Measuring 2.5 inches, the Mural series is very solid when stretched with heavier canvas fabrics.






Starting from 32" to 42", depending on the profile cross-braces are added for better support. But, ours are not the typical "passive" braces. Our cross-braces are "active" in that they completely lap the rib of the T-Bar and are bolted to it making the entire frame one homogeneous unit. The stretcher bars are thereby prevented from twisting inward by the force of the canvas. This counter-force is not available with typical cross bars. Yet, our bars are also key-able. Simply loosen the bolt, use a hammer or a c-clamp to sink the key deeper and re-tighten the bolt.

Note: For easy shopping, our web products are limited to 8' lengths. Beyond that, the stretcher bar frames would be constructed with seams and are available by special quote. Prices are comparable to our web products.


Bar Material

Our T-Bars are offered in two materials; Premium Radiata Pine or Birch Panel Material. The select, kiln-dried Radiata Pine is not compromised by knots or finger-joints. Another popular choice is Birch Panels. These are super-straight and they add a greater degree of warp-prevention.

Either way, each bar is sealed with shellac to act as a buffer between the canvas and wood acids as well as to help reduce any potential of warping, aging or deterioration of the wood itself.


Canvas Fabric

Claessens Belgian Linen, 11.3oz Oil-Primed

This linen roll features a very fine texture, 2 layers of oil primer. The thread configuration is 23warp/23cm weft, and before priming it has weight of 10.5oz. It is the ideal choice for portrait and detail style painting.

Fredrix 574 Cotton, 9oz Acrylic-Primed

Also know as Knickerbocker, this canvas has a smooth, fine texture, perfect for smaller paintings and fine detail work.

#12 Cotton Duck, 15.5oz Triple Acrylic-Primed

This is a popular, general purpose canvas with good strength and smooth surface. It's heavy enough for rather large paintings but fine enough for smaller works as well.

#10 Cotton Duck, 17oz Triple Acrylic-Primed

Heavier than #12, this canvas has the added strength to stand up to very heavy paint applications and for larger works.

Caravaggio Polyester, 7.5oz Double Acrylic-Primed

This synthetic canvas has a smooth consistent weave with good strength and optimum archival qualities.

Note: We only use stainless-steel staples in our stretched canvases. Some aficionados swear by the traditional copper tacks. There are some respected conservators that say they are indeed better. For the rest of us, there's the new-age and entirely satisfactory staple. However, if you have any old canvases hanging around, you can easily see that they are very susceptible to rust, even if they are zinc-coated. For that reason, we only use stainless-steel staples on our canvas products.

Edge Treatment s-silent-aspirations.png

Many artists, when producing works on gallery-wrapped canvases with the intent of hanging the work unframed, typically paint the edge, most often black. We can save you a lot of time by doing that for you! Imagine, after completing your work, you could simply peel off the acid-free tape along the perimeter and have a clean, black edge, ready to hang.

Keep in mind that for an oil-primed canvas, we will use oil paints and acrylic for the acrylic-gessoed canvases, both in a nice gloss black.

Canvas Surface Toning

Nobody likes to paint on a blinding, stark white surface! But why go through the trouble of toning the canvas yourself? We offer to perform this tedious task for you. You can choose from the following tones:

  • Raw Umber
  • Burnt Umber
  • Burnt Sienna



This isn't your run-of-the-mill shipping box we're talking about here. Our unique Fat Canvas shipping cases are custom-fitted for your canvas with the intent of providing your art patrons the means to protect their investment while moving, storing or even when loaning fine works out to friends. The painting will be cradled and cushioned within the case and getting it in and out is a snap.

  • Standard - Very study and crush resistant, a step above what's normal.
  • ArtPorter - Reinforced faces for extra protection and shipped stretch-wrapped.
  • ArtPorter Plus - 3" of extra space for works that are headed to the framer. If you're going with an extremely wide frame that just won't fit in that space, simply let us know, and we try to accommodate.
