Rockler Dust Right® expandable hoses are made of an amazingly elastic, flexible polymer material that can stretch up to 7X its original length for convenient cleanup in distant corners, or to attach to a power tool. Once your finished with it, it collapses into a compact stack for storage. Thanks to its flexibility, it slinks with ease around obstacles without kinking or binding. This improved hose weighs 30% less than previous versions, and is offered in a blue translucent color. Ideal for use in small shops, and with small dust collectors where a single hose is swapped among multiple machines and cleaning implements.
