The Viper Channel is a wide body channel that offers a a shape on the ends of the channel that promote easy detailing, the Viper is part of the 3×4 Series of Channels invented in 1985 by Soren Samuelson. 

This design honors Mr. Wieland of Australia who was the first person to modify the Sorbo 3×4 Squeegee by removing the front portion.

The Viper cleans closer to the Frame leaving less water and is excellent when use with the "S" technique.
