A lumber assembly and finishing system for use in assembling constructs includes a lumber table configured to support arranged pieces of lumber. A press station presses nailing plates into the pieces of lumber to join the pieces of lumber together to form the lumber construct. A lumber construct transporter moves the arranged pieces of lumber from the lumber table to the press station while keeping the pieces of lumber in their arranged configuration.

An anchor assembly for hanging an object on a wall includes a first anchor component and a second anchor component. The second anchor component is pivotably associated with the first anchor component for movement between an anchoring orientation and a non-anchoring orientation to enable staged installation of the anchor assembly into a wall. At least one wall penetrating retainer extends from each of the first and second anchor components. When the second anchor component is in the anchoring orientation a curved configuration of the wall penetrating extent of the retainer of the second anchor component opposes a curved configuration of the wall penetrating extent of the retainer of the first anchor component to form a jaw-type arrangement.

A nail plate stack de-bander system for de-banding a nail plate stack including a plurality of nail plates coupled together by a band. The nail plate stack de-bander system includes a stack press assembly and a stack de-bander assembly. The stack press assembly includes a stack press. The stack press assembly is configured to receive the nail plate stack. The stack press is configured to compress the nail plate stack such that the band expands outwards from the nail plate stack. The stack de-bander assembly includes a stack band spear assembly. The stack de-bander assembly is configured to move the stack band spear assembly to cut the band from the nail plate stack to de-band the nail plate stack.
