The EtchMaster® Flex Hose Assembly is a great alternative to the heavy, inflexible sand hose. Meant for use only inside a cabinet, this option greatly reduces operator fatigue. Attach the assembly to the end of the sand hose. Pass the nozzle holder and flexible hose through the hole in the cabinet and lock the adaptor in place. Anyone doing decorative sandblast will appreciate the extreme flexibility of this hose and the very light nozzle holder on the end. It requires very little effort to accurately direct the nozzle. Are you using a heavy valve on the end of your sand hose? By replacing it with a Flexible Hose Assembly and adding an EtchMaster® Air-Activated Foot Switch, you will see a huge difference in productivity.
