The RoundUp Pro® 4-gallon no-leak pump backpack sprayer has a superior comfort 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 your shoulders. Equipped with a comfort grip handle and lock-on mechanism, this shut-off system can be easily operated with heavy-duty work gloves. The 21-inch heavy-duty poly wand provides reach and accessibility to difficult spraying areas. Multiple nozzles are included for versatility in both application rates and patterns. It includes a 50-inch heavy-duty nylon-reinforced hose and strain relief system, preventing the hose from kinking at the chemical exit point. This backpack sprayer features an internal piston pump. As seals wear over time, the unit keeps the chemicals in the tank and off of the user's back.
