Once the bed rail height is determined, the bed rail is then aligned in front of the desired slots
and is inserted. The locking fingers on both ends fit into the corresponding punched holes.
When the bed rails fingers are fully inserted, a downward movement will then engage them into the
upright forming a rigidity affixed attachment of the bed rail to the upright frame. A downward blow with a hammer on both
bed rail ends will securely wedge the bed rail and the upright into one rigid unit assembly. Select-A-Level Racks are designed
to fit tight....stay tight!
