MTM Hydro's Unloader Mounting blocks offer a convenient way to mount your unloader to a pressure washing frame. Unloader blocks are considered a 'Wet' accessory and are mounted to a pressure washing frame using the two 2" bolts and hardware provided in this kit. The unloader block has a 90 degree elbow allowing the user to install a bottom-mount unloader. Before purchasing, be sure to review required threads in either 3/8" or 1/2".

For a corrosion-resistant, upgraded version, see the Brass Unloader mounting block.
