ABSTRACT:
An improved adjustable center door pivot assembly is disclosed which can be mounted to a threshold without the need for a separate mounting bracket. The adjustable center pivot assembly permits the height of the pivot spindle to be adjusted without removing the door. Further, the height of the adjustable center pivot assembly which projects above the threshold is sufficiently short that the pivot assembly can be used with a standard door having a standard 21/32" web.
