NOTE: MINOR FITTING MAY BE REQUIRED - Not all hammers are made to exact tolerances. Sometimes you may need to lightly file the opening of your Grovtec hammer extension to assure a secure fit. We recommend using a small metal file. You can also use some liquid bluing to re-coat the bare metal if necessary.
