Bull floats allow the operator to reach far out onto a slab without having to get on the concrete with knee boards. This is because these floats consist of a long handle attached to a wood, resin, aluminum or magnesium float. The handle can measure anywhere from 4 feet to 16 feet long. Handles either snap onto the float or are threaded on. A bracket assembly allows the angle to be adjusted to different positions so that the float can reach the concrete surface at the angle needed for the job. The floats are also available in many different lengths and widths. They are designed with square or rounded edges and the choice of which to use is usually a function of user preference.
