The No-Roll Knockdown can be configured into dozens of different knockdowns in one.
With two Mirror Polished Tips, you can use it bare and still have better reach and visibility but when coupled with the Caps and Pressure Fit Tips, you can truly make this knockdown your own!
My favorite is to use a Black Magic Tip on one end and a Silicone Cap on the Patent App. Pending No-Roll arm. This keeps it from rolling away, nothing metal to touch the vehicle, precision, and cushion and just pop off a pressure fit tip and have the ultimate precision of the mirror polished tip.
