The Solo adjustable hose end sprayer is a safe, easy, touch-free way to apply any chemical or treatment without measuring, pouring, or mixing. The unique design adapts to fit directly on the bottles of most major brands of concentrate chemicals eliminating contact and waste of product. Simply remove the chemical bottle and cap and recap the chemical to store with minimal clean up. Left-over concentrate will be undiluted so it can be poured back into its original container for later use. It also features anti-siphon valve in swivel connector, instant on/off trigger, precision metering system for accurate mixing ratio of concentrate per gallon of water, and a quick connect coupling for easy hose attachment. Liquid dispensed through top nozzle hole only: stream for high places and tough rinse jobs, shower for delicate flora, flat fan for large areas, and cone pattern for shrubs. Comes with a durable 32 Oz. plastic canister which works as a container to apply chemicals or can be used as a traditional hose-end sprayer. 50 psi. 10 year limited warranty.
