How to assemble the ZIPCHOCK stand
Insert the floor plate into the front plate with a short twist.
Install the right side plate in the large slot. Install the left side plate in one of the narrow slots to loosely fit the tire.
Place one bolt under the floor plate; this locks the 4 plates as an assembly. The stand can be transported where needed.
Place the second bolt near the front plate.
Use both bolts to remove any side play.
