Wood is vulnerable to environmental conditions that left uncontrolled will warp. Aluminum Strainers provide a dimensionally stable support that withstands greater fabric tension and is guaranteed to never warp. These strainers are simple to hang on French cleats. Because fabrics will not create an impression on the perimeter over time, as they do in wood supports, aluminum strainers can be re-stretched over and over again. There are a variety of canvas and linen options.
The standard strainer depth is 1½".
Lucius Hudson, Inc. has been manufacturing their patented aluminum strainers in Southern California since 2003, and they have become a popular solution to the instability of wood supports.
