The LoPro Series teeth are installed as shown below. The tooth fits up into the pocket, the spacer and nut go on top. The pockets are reversible, with one threaded hole and one counter-bored hole per pocket. Because of this, the LoPro bolts are able to feed into the wheel from opposite sides of the wheel to ensure a strong secure setup.
The beveled edge on the spacers for the LoPro series are designed to specifically fit into the chamfered end of each pocket.
