The present invention relates to a door frame, particularly a door frame for a pre-hung door assembly, which is foldable to minimize storage space and to allow for enhanced logistic efficiencies. The door frame contains parallel, spaced apart, vertical jambs and a horizontal header connecting the top ends of the jambs. Each of the jambs and the horizontal header contains a front section and back section that are hingedly joined so that then can be folded on to each other. The hingedly joined front and back sections allow the door fame to be foldable to minimize space occupied during storage.

Disclosed are a ceramic tile leveling bracket, pushing and clamping pliers, and a ceramic tile leveling and laying system. The ceramic tile leveling and laying system comprises: a ceramic tile leveling bracket, an insertion block, and pushing and clamping pliers, wherein the ceramic tile leveling bracket is disposed at a junction of at least two adjacent ceramic tiles, one end of the insertion block is inserted into an insertion block receiving portion of the ceramic tile leveling bracket, and the pushing and clamping pliers push and clamp the insertion block into a ceramic tile leveling bracket such that a bottom face of the insertion block is tangent to upper surfaces of the ceramic tiles. The ceramic tile leveling and laying system is easy to operate, and improves the laying efficiency and laying quality.

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.

An adaptable door mounting support for acquiring a door gap and for supporting a door slab. The door mounting support comprises a frame member including first and second A-shaped segments interconnected by a rectangular bottom section and together defining a door support channel therebetween, and a tie device configured to meter the door gap and hold the door slab off the ground. A width of the door support channel is equal or larger than a thickness of the door slab. The tie device includes a cable tie extending between the A-shaped segments and across the door support channel, and a locking member attached to the cable tie by sliding over the cable tie. The locking member is slidable over the cable tie in one direction only and is lockable on the cable tie to adjust a distance between the cable tie and the bottom section of the frame member.

A barrier device includes a horizontal portion formed of a polymer, the horizontal portion having a largest substantially planar surface and a thickness perpendicular to its largest substantially planar surface. The barrier device includes a vertical portion formed of a polymer and coupled with the horizontal portion, the vertical portion forming a substantially ninety-degree angle relative to the horizontal portion, the vertical portion having a largest substantially planar surface and a thickness perpendicular to its largest substantially planar surface. In implementations the thickness of the vertical portion is substantially equal to the thickness of the horizontal portion. A width of the horizontal portion, perpendicular to the vertical portion, is shorter than a height of the vertical portion perpendicular to the horizontal portion—in some cases no more than one third or one fifth its size. In implementations the barrier device may be used to protect an installed baseboard.

A tile spacing device and accompanying system and method are disclosed for spacing a plurality of tiles having a contour. In one embodiment of the tile spacing device, the tile spacing device includes a U-shaped band having a body with two branches extending parallel therefrom and an opening therebetween. An arm having a lateral end extends proximally from one of the branches into the opening. Two interlocking connectors are respectively positioned on the body at the opening and on the arm. In one embodiment of the system, two tile spacing devices complimentarily releasably mate when the tile spacing devices are opposing and perpendicularly displaced to interlock the interlocking connectors.

A system and device for leveling and aligning tiles and a method for leveling and aligning tiles are disclosed. In one embodiment of the tile leveling system, a tile leveling device includes an upright body having a head and base at opposite ends thereof. The base and the upright body are integral prior to a frangible separation. The tile leveling device is selectively threaded through a line-of-sight opening of a wedge device for use in an operational configuration.
