Gilmour R15C Multi Use Poly Wand for Spray Doc Sprayers (Discontinued by Manufacturer)
Part of Gilmour's Spray Doc line of sprayer accessories, this poly wand replacement kit comes with an adjustable nozzle for fine misting to stream spraying. The wand extends to approximately 18 inches beyond your reach, but the so-called "flexible" poly material doesn't seem meant for flexing and requires some effort to stay put. Of course, Gilmour's free-replacement policy for all of their replacement products (should they wear) makes their kits especially attractive because, once paid for, you'll never have to pay to replace them again.
