Step 1:
Determine the location of the traffic calming device and use chalk to mark the center lines (parallel and perpendicular to the direction of the street) and border lines on the surface.
Step 2:
Assemble and position the units, starting from the center line (parallel to the direction of the street). Figure 1 illustrates how to interlock the units. Note: Make sure the units are tight and well aligned before moving on to step 3.
Step 3:
Drill 9/16” dia. holes into the surface, through the existing holes of the placed units. The holes should be 4”-5” deep in order to accommodate the plastic shields that are 3” long. After each hole is drilled, insert a plastic shield in order to keep the units from shifting. The flange of the shield should rest on top of the installation surface (asphalt or concrete). Note: Make sure the holes are clear of dust and debris before installing the shields. (A portable blower is useful for this purpose.)
Step 4:
Bolt down each unit with the provided lag bolts and washers. Do not over tighten.

Mini Humps require minimal maintenance. Periodically inspect the bolts and tighten if necessary.
