- Flip the base platform upside-down and position the pre-assembled caster assemblies over each set of the (3) blind holes as shown below.
- Insert a #6 x 3/8”, socket-head cap screw (there are three included with each Caster Wheel Kit) into each of the three holes in the caster’s mounting plate. Tighten using the 5/32” ball end hex key.
Retain the ball-end hex wrench for future use—you’ll need it when you install the PING))) Ultrasonic Distance Sensor Protector Stands. The pre-drilled screw holes are sized for self-tapping by the #6-32 socket-head machine screws.
- Next, attach the two pre-assembled caster wheel assemblies using (3) #6-32 x 3/8” socket head screws per wheel.
