It has taken years for the dust hose industry to mimic the shape-holding characteristics of the Flex Straw. But now you can have a dust port on your CNC table temporarily aimed right where the dust is created. Its ability to twist, bend, expand, or contract, and then hold this shape, makes it ideal for situations where the conventional hose can not be used. Made from durable polypropylene plastic in standard 2-1/2” diameter. When compressed this hose measures only about 12”, yet it stretches to more than 3 feet when fully extended.
