Custom Stretcher Bars

We provide custom, fully keyable stretcher bars and braces made from two types of kiln-dried wood: Tulip-poplar (Liriodendron tulipifera L.) and American Basswood (Tilia Americana).


Bar and brace joints are designed with mortise and tenon to ensure the canvas can be properly tensioned while keeping the connections strong. Our stretcher bars and cross braces are fully keyable and include engineered, injection-molded wedges. We offer stretchers in six profile designs. Unless Canvas Stretching is requested, stretchers are delivered or shipped as unassembled bars. 


For orders or quotes on custom stretchers, including large folding stretchers, fractional sizes, metric dimensions, stretched and primed canvases, or other specific requirements, please fill out the Request a Quote form.


All our products are made to order from rough lumber. Lead times fluctuate weekly based on demand. Refer to the website's top banner for the most current lead time information.

DoubWorks stretcher keys for tensioning canvases

To re-tension a canvas using our engineered corner keys, place a key into each of the two slots located at all four corners of the stretcher. Tap each of the eight keys gently until the corners are uniformly expanded. Should your stretcher have cross braces, position a key into every joint of the braces and tap them in the same manner as the corner keys.
