Aluminum Stretcher Bars

These premium architectural-grade aluminum stretchers are ideal for very large canvases (up to 30 ft or more!), as well as in the following situations:

• where a thinner canvas is desired in a large size
• in challenging environments, including fluctuating temperature and humidity
• where tolerances for movement within the stretcher frame are very small
• where fire code regulations make the use of wood stretchers unacceptable
• where artists wish to keep a "master frame" for painting which will stand up to repeated reuse

A mechanical keying system allows full adjustment of canvas tightness on the bars and braces. Learn more about our aluminum stretcher bars here.

Available in two thicknesses, these stretcher bars can be purchased online in sizes ranging from 24-90” (~61-229 cm) - please contact us at 1-800-561-4944 or submit a quote request to order frames outside of this range.
