Hose reel for suction hose 3″ - 4″ end mounted fold-down stainless steel drum

This suction hose reel is an accessory designed to be mounted on sludge extractors to suck up sludge (or similar liquids) from manholes, sewers and drains.
The suction hose reel is typically mounted on the back of the vacuum cleaner.
The fold-down hose reel makes work easier for the operator by bringing the hose closer to the work area.
