Abstract: A deck support may be created to hang from a top plate of a wall in residential or other construction. An upright or leg may provide support of the weight of the deck supported on a foot extending laterally from the leg. The foot may be provided with a climber attachment that secures the foot extending horizontally from the leg, and yet is readily adjustable without alignment, line-of-sight adjustment, removal or repositioning of pins, and the like. The apparatus may operate to support a user installing soffits, fascia, trusses and other assemblies near the upper portions of walls at any stage of construction. Adjustment may be done safely by a single user employing a single hand. Alignment and engagement are simple and automatic by the climber securing the foot to the leg. A hanger bracket may extend adjustably across the top plate of a wall to support the leg extending vertically therebelow.
