Stop collar.
Spring centering kit will limit rotation of arch to
90 degrees of rotation in each direction, no more
. There is no way
to increase rotation in one direction more than 90 degrees and still have spring return. However one can limit rotation
to less than 90 degrees in one or both directions by adding 1 or 2 more Stop Collars (75000-655W).
