ABSTRACT:
A vertical alignment device (10) between a downwardly extending upper spindle (12) on an upper mounting plate (14) of an upper pivot assembly (16) in a head jamb (18) and an upwardly extending lower spindle (20) on a lower mounting plate (22) of a lower pivot assembly (24) on a floor (26) for a glass door structure (28) comprising a body (30). A facility (32) is for attaching in a removable manner an upper portion (34) of the body (30) to the upper spindle (12). A plumb line (36) is provided with a plumb bob (38) affixed to a first end of the plumb line (36). An assembly (40) is for securing a second end of the plumb line (36) to a lower portion (42) of the body (30). The plumb bob (38) will hang down on the plumb line (36) to indicate an aligned location for the lower spindle (20) when the lower mounting plate (22) is bolted up on the floor (26), thereby allowing the glass door structure (28) to operate properly in a swinging manner.
