3/4″ Basic Stretcher Bars

Our smallest and lightest stretcher profile, Basic canvas stretcher bars are widely used for both custom and stock-sized stretcher frames. They are ideal for smaller canvas sizes, generally under 36″ (90 cm). Braces are recommended for bars starting at 30".

WARNING: Some high-tension applications such as sizing of raw linen with RS glue require stronger stretchers to prevent twisting of the stretcher frame. If these are the materials you plan to use, please contact us for assistance. Otherwise, this guide can help determine the best profile and bracing for your needs.

Stock braces are now Universal!

Our regular braces are made to fit with our stretcher bars using mortise & tenon joints which must be cut during production and cross-braces must be machined with dado joints to nest together. For these to fit properly, we need to know the size combinations that will be used and, when purchasing stock-sized bars and bundles, you don't always know when you place your order exactly what combinations you will end up using. To resolve this, our "stock" braces will now use our Universal Bracing system which uses screwed-in brackets to mount to the stretcher bars and allows braces to be used interchangeably with any other size. Take advantage of the cost savings of buying in quantity without sacrificing your creative options!

If you prefer to stay with our regular mortise & tenon braces, simply order as complete stock-sized or custom-sized frames.

STRETCHER BAR MATERIAL: Kiln-dried, solid or finger-jointed clear white pine

CUSTOM SIZES: Order from our custom sizes page for any size between 6″ and 36″ (~15cm-92cm) – accurate to the nearest 1/16” (1mm). For special orders outside of our stock or custom size range, please contact us or fill out our quote form.

BRACES: 1/2” x 3” clear white pine normally spaced at no greater than 30” centres starting at bar lengths of 30”. For frame sizes less than 30”, braces may be used to provide protection to the back of the canvas.

Stock braces are made using our Universal Bracing system which can also be used in situations where you want to add bracing to an existing frame.

Braces for our stock and custom-sized frames are made with a 1/4” x 3/4” x 3” tenon on each end which fits into a matching mortise on the stretcher bar. The brace includes a very effective and attractive “hidden” slot design that holds the keys firmly in place.

In situations where braces must cross each other, a 3” wide, 1/4” deep dado joint is machined in each brace to provide a tight and flush nesting of the cross-braces. This joint is fastened together with a low profile screw inserted during final assembly.

KEYS: 3″ long and 5/32″ thick; made of a high-quality birch plywood. Two keys are included for each stretcher bar and brace.
