Keep masonry sand free of debris with the Shake n' Rake SNR-10, a motorized sand cleaning rake. The 1/4-in. screen sifts tiny debris, and has an optional 3/8-in. screen for damp locations. The Shake 'n Rake's high-speed, up-and-down shaking motion mimics the manual lofting of sand that was formerly done by hand. Berto. 541-826-8301.
