Our fork brace is designed with special slotted centering holes so it impossible to put the forks into a bind when installed properly. With a common two-piece design, it is impossible to allow for machining and assembly tolerances which can lead to very high levels of stiction, poor suspension feel, worn bushings, and premature fork seal leaks. You will have less flex at parking lot speeds and additional stability on the highway.

It sounds like they are distinguishing their brace from "a common two-piece design," by emphasizing that with their "special slotted centering holes" you eliminate the risk of "binding" the fork tubes if installed properly. They then go on to describe the "horrors (marketing)" of binding the tubes by using one of those inferior "common two-piece designs." Just my interpretation.
