This new channel works in your existing Unger handles, but it is fully designed to give the blue squeegee blade added stiffness and a better angle to aid in laying down the film and extracting more water per squeegee pass. The Extruder comes with an integrated lip that the Unger handle jaw slides into making a positive connection between handle and channel/blade combo. The channel also extends further onto the surface of the blue max material which adds stiffness to the blade. Finally, the channel clamps into the handle in such a way that places the blade at a slightly better angle to the handle for better extraction capabilities.

Note: The Extruder is the alloy channel only. The blue squeegee blade insert and Unger handle need to be purchased separately.
