A pivot assembly employs a pivot block to resist lateral forces and facilitate door alignment. The assembly includes a sleeve, pivot pin, pivot block and jamb bracket. The jamb bracket is connected to a corner between a jamb and a floor. The pivot block mounts on to the jamb bracket with anchors that engage serrations in a slot of the jamb bracket. The pivot block includes two halves resiliently connected at one end and separated by a gap, with a conical socket centered along the gap. A pivot pin is threaded into a sleeve mounted to the lower edge of a door to adjust height. A head on the lower end of the pin engages grooves in the pivot block socket. The pivot block halves separate to accommodate the pivot pin, and to cause the pivot block halves to be anchored in the jamb bracket. To properly align the door, the door is lifted to disengage the pivot pin from the pivot block. Vertical height is adjusted by rotating the pivot pin in the sleeve. Horizontal adjustments are made by pinching or squeezing the pivot block halves in order to slide it along the jamb bracket slot.
