The BROWN Hammer-Spacer HSP-I3 is a square tool made of steel that slides over the Oz-Hammer (OH-01) and keeps it centered on the inside of the Oz-Post sleeve when installing the I3-850. This Hammer Spacer is used in conjunction with the OH-01 Oz-Hammer. The OH-01 Oz-Hammer is 2” in diameter. The I3-850 is 3” inside diameter so we recommend using the HSP-I3 to keep the Oz-Hammer (OH-01) centered in the Oz-Post sleeve during installation.
