The Inverse Curve was originally developed to fit in a constrained space, such as the Zoethecus rack shown above.
The performance of the Inverse has proved to be superior to a rectangular shaped piece of the same dimensions.

With surprising performance, we have designed a number of sizes for a wide variety
of applications.
Sizes and pricing can be found below.  Maximum dimensions are shown.

Custom designs may be available.  Please contact us with your requirements.
