The PourAway Cadet registers full at 23 gallons, but holds up to 30 gallons of liquid. The Cadet comes with a nesting, removable strainer to keep solids from clogging the unit and the custodial sink. The wide drain hose allows for quick and easy emptying. The sturdy handle and commercial grade wheels make moving the cadet full or empty safe and easy. The caster brakes allow for stationary placement when in use.
