Kraft Tool Co.® CC334 1-3/8" Diameter Button to Male Threaded Adapter 24 per Case. Expand the use of your tools with this adapter! All your concrete tools can use the same button bull float handle with this adapter. This tool allows finishers to use lightweight 1-3/8" diameter bull float thread handles with threaded bracket assemblies. A strong male threaded end creates a strong attachment to bull floats, fresnos and other threaded handles and brackets. The threaded end is secured to a lightweight durable aluminum tube with holes to accept button bull float handles. The threads are uniquely designed to allow connections to both bull float handles and brackets as well as broom thread brackets. The threaded end is cast aluminum for a strength and consistency in threads.
