The perfect tool for many jobs such as flatwork, paving for an especially flat surface. Made of Genuine Extru-Lite? Magnesium, which is 30% lighter than aluminum. The extruded magnesium makes for an extra strong float. The 96″ x 6″ round end float is properly balanced to prevent digging into concrete as it finishes. The 2″ sides produces the channel for which the tool is named. This special design creates a stiffer, more rigid blade that resists warping to improve flatness for smoothing paving work. Designed for use with 4-hole brackets (sold separately). Kraft Tool’s Double-Tilt Action Brackets (#CC270, #CC290, #CC294, and #CC296) or Single-Tilt Action Brackets (#CC696 or #CC800) are popular choices for brackets. Handle choices are determined by the user’s choice in bracket.
