This 4 gal. Internal Piston Pump Backpack Sprayer has a deluxe harness with wide, padded shoulder straps that fit snuggly across the torso and curve to the contour of the user”s body. An adjustable hip harness assists with weight distribution, relieving burden from the user”s shoulders. Equipped with a comfort grip handle and lock-on mechanism, the shut-off system can be easily operated with heavy-duty work gloves. Multiple nozzle tips are included for versatility in both application rates and patterns and can be stored in the waste belt. Includes a 50 in. heavy-duty nylon-reinforced hose and strain relief system that prevents the hose from kinking at the chemical exit point. As seals wear over time, the unit keeps the chemicals in the tank and off the user”s back.
