Description
Hand operated gravel extractor is made of 1 1/2 inch PVC pipe with an adjustable tension rubber plug. The T-handle is made of plated steel. Perfect for crevicing and sniping. Total length is about 30 inches. The vacuum chamber is 1 1/2 x 20 inches and the total weight of the unit is only 2 pounds.
To adjust suction: adjust the bolt by opening the nozzle end and hold it it firmly, then twist the t-handle to tighten or loosen.
Also remember there is not a large reservoir, so you should probably dump your material every 1 to 4 stokes on average depending on how much material you suck up.
