A double door assembly bottom restraining device and method provide stability to the double door assembly during manufacturing and shipping. The double door assembly bottom restraining device may be installed on the bottom of a double door assembly.

A door hanging apparatus includes a base for ground contact. A height adjustment bracket is located above the base and includes a lifting platform for supporting an underside of a door. A leadscrew assembly, including a leadscrew, interconnects the base and the height adjustment bracket. The leadscrew assembly operates to vary spacing between the base and the height adjustment bracket in response to rotation of the leadscrew.

A pair of jacks for lifting doors to facilitate adding hardware to the doors, each jack comprising: a clamp for clamping one end of a door; a swivel connected to the clamp via a cylindrical member; a telescoping shaft attached to the rear end of the cylindrical member; a crank arm attached to the top of the telescopic shaft for selectively adjusting the height of the telescoping shaft; and a base including at least four wheels for moving the jack along the floor, wherein the bottom of the shaft is attached to the base.

The device comprises a combination of an inflatable air cushion member of a flexible but non-stretchable air tight sheet material and a support block. The inflatable air cushion member is formed as a bag unit comprising opposite layers of said sheet material provided face to face and joined along an edge area to form a double layer edge.

The device comprises a plurality of inflatable air cushion members (6) of a flexible but non-stretchable air tight sheet material (1) in hose-connection (11) with an inflation tool (12). Each inflatable air cushion member (6) is formed as a bag unit comprising opposite layers of the sheet material (1, 1′) provided face to face and joined along an edge area (4) to form a double layer edge. Surface modification of the cushion members, for example by a sleeve or pouch into which the cushion members are inserted, is used to adjust the properties of the device for an optimized lifting process.

A double door assembly bottom restraining device and method provide stability to the double door assembly during manufacturing and shipping. The double door assembly bottom restraining device may be installed on the bottom of a double door assembly.

A ready-to-install door system including, prior to installation, a frame including a hinge-side vertical bar attached at a top end to a horizontal bar that is further attached to a top end of a latch-side vertical bar, and a threshold portion that is attached to a bottom end of the latch-side vertical bar and a bottom end of the hinge-side vertical bar, a door rotatably attached to the hinge-side vertical bar of the frame, and at least one first removable spacer located at a first location of the door between the door and the frame, and configured to at least maintain a desired squareness of the door system prior to installation, wherein the first removable spacer is configured to be removed after the door system is installed.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for installing a closure assembly into a framed opening having sheathing arranged around the framed opening. The apparatuses, systems, and methods may include use of at least one support bracket along the framed opening and the sheathing.

A door lifting device comprises a base plate, a fulcrum extending perpendicularly from the base plate, and a balance beam having a first end and a second end pivotally connected on the fulcrum. The balance beam includes a foot plate attached to the first end of the balance beam, and a door carriage attached to the second end of the balance beam. The balance beam can be adjusted to a selected height relative to the base plate. When the selected height of the balance beam relative to the base is increased, the pivot point is increased relative to the base plate. The balance beam can further, based on the selected height, be pivoted from a first location to a second location such that the door. When the pivot point is shifted away from the door carriage to the second position from the first position on the balance beam, the height of the door carriage relative to the surface is adjusted from the first height to the second height.
