The Knucklehead? II double tilt action button float bracket attaches to fresnos and both 2-hole and 4-hole bull floats. The patented (US Patent #4,335,485) bracket is made of rugged, yet lightweight aluminum for durability. Control the pitch of the blade with a one-to-one turning ratio of handle to blade. Turning the handle eliminates the need for bending and lifting when moving tools across fresh concrete. Geared tilt action makes for smooth movements. A protected grease reservoir for longer wear. Use with 1-3/8″ or 1-3/4″ button bull float handles or adapters. Add an adapter for use with threaded bull float handles. Fits 2- or 4-hole bull floats.
