Our 3/8 inch and 5/8 inch band clamp hand tool applies band clamps to complete the connection between shank style couplings and hoses. This tool is used for 3/8 inch band clamps and 5/8 inch band clamps. By inserting the tail of the clamp into the tool and ratcheting the handle you can pull tension on the band creating an ever lasting bond between the coupling and the hose. This is a punch style banding tool and is used in conjunction with a hammer.
