Why use Tall Top Parts?
Some applications have configurations with only a slight difference between shaft centerline heights. Many times the adjustment range of the chocks is sufficient to accommodate the differences. But, if 1/4" to 3/4" in additional height are needed, then a taller top part is more economical than a full tall line assembly.
Also, on occasion during assembly of the package, the gap height is not always “as designed”. Subsequently, when the RotaChock is fitted and adjusted only to find the height difference ends up beyond the maximum adjustment height for that style of chock. Instead of adding shims, we have engineered a way to adapt for the situation - Taller Top Parts. All of our standard top parts can be swapped out for a taller design, thus making up the gap with all the stiffness and strength of the original design.
