Profile: Lindley, Inc. manufactures concrete screeding equipment. Our Vibra Strike Rattler is a self-contained, gas powered, concrete vibrator that is simple to operate, even for the single worker. Our Vibra Strike II is just as quick and versatile as the original, and with the 4 stroke engine this is a power screed that delivers performance. The new one piece design eliminates over 60 nuts, bolts, studs, washers, tensioning rods, and brackets. By reducing this many parts from the float, overall functionality is greatly improved. The unique geometric shape of the float allows it to be used as both a float and curl edge, when screeding from the top of forms.
