A molding piece, comprising a molding piece structure and at least a first magnetic element, wherein cross-sections of the molding piece structure along imaginary planes perpendicular to the molding piece structure imaginary axis are substantially the same size and shape. In some embodiments, the first magnetic element is in a first groove in the molding piece structure, cross-sections of the first magnetic element along said imaginary planes are substantially the same size and shape, and/or the molding piece structure further comprises a protruding rib. Also, a removably engaging device, comprising a removably engaging device structure and a first element, wherein the first element comprises a magnetic element and/or a magnet-adhering element. In some embodiments, a removably engaging device structure comprises a rib and/or a groove. Also, kits and systems comprising molding pieces and removably engaging devices, and methods.

A system for crown molding that enables safely incorporating electrical and communications cabling within crown molding by creating one or more protected paths which inherently prevent overly sharp bends in crown molding corners and by mitigating damage from penetrating punctures through a decorated face designed to fracture when improperly penetrated by a screw or nail, and enables the secure installation of hardware either concealed within the molding or securely and favorably positioned through the decorative face to view or sense a room, and enables additional cable capacity that is concealed within a light reflector to increase lighting efficacy as well as power and data delivery capacity.

In one embodiment, a system comprises a first baseboard element, a second baseboard element, and a spline configured to couple with the first baseboard element and the second baseboard element. In another embodiment, a system comprises a first crown element, a second crown element, and a spline configured to couple with the first crown element and the second crown element. In another embodiment, a system comprises a crown spline, a baseboard spline, and a wall element configured to be coupled with the crown spline and the baseboard spline. Other embodiments are disclosed herein.

The invention provides an elongated lighting element (200) for attachment to a building part (10) selected from the group consisting of a wall (11), a ceiling (12) and a floor (13), wherein the building part (10) comprises a first attachment unit (131) and a first electrical power connector (141), wherein the elongated lighting element has a front side (210) and at the other side of the front side (210) (i) a second attachment unit (231) for forming with the first attachment unit (131) said attachment to said building part (10), (ii) a second electrical power connector (241) for forming an electrical connection with the first electrical power connector (141), and (iii) a plurality of solid state based light sources (250) configured to provide light source light (251) and functionally connected with the second electrical power connector (241).

Snap-in trim systems include a mounting element securable to or integrated with a structural component of a building. Structural components include modular wall components suitable for having decorative or structural trim attached thereto. The mounting element extends longitudinally along a length of the structural component. A longitudinal connection element is secured to the mounting element along the length thereof. The connection element attaches to the mounting element at an attachment interface either anterior-perpendicularly, lateral-parallelly, or anterior-lateral-diagonally. A trim element is connected to or integrated with the connection element. Connected trim elements include an alignment element for ensuring proper positioning of the trim element relative to the connection element. Trim elements include baseboard, crown molding, window casing, door casing and door stops.

A baseboard element including a nose portion, a riser portion coupled to the nose portion, and a wall groove portion coupled to the riser portion. The nose portion includes a nose bottom section and a nose face section. The riser portion includes a riser section approximately perpendicular to the nose bottom section. The nose portion is positioned only on a first side of the riser section, and the wall groove portion is positioned only on a second side of the riser section, the second side opposite the first side. The nose bottom section comprises a nose bottom edge that is located at a terminal end of the nose bottom section and that is located closer to a plane defined by the riser section than the nose face section is to the plane. Other embodiments are also provided.

A system for installing pre-painted moldings. The system includes pre-painted moldings each configured to be fastened to a wall by fasteners. The system also includes a caulk material, filler material, concealer material, and touchup paint each color matched to the paint color applied to the moldings. The caulk material is configured to fill a gap defined between each of the moldings and the wall to which the molding is fastened. The filler material is configured to fill a gap defined between any abutting portions of the moldings. The concealer material is configured to conceal any surface disturbances caused by the installation of the fasteners. The touchup paint is configured to adhere to the paint pre-painted on the moldings. The system may also include a marker configured to apply a coating color matched to the paint applied to the moldings, a scraping tool, and/or a buffing tool.

Adjustable molding assemblies and methods for bridging a gap between building elements are provided. The molding assembly includes a molding that includes a cover portion with opposing ends that are configured to contact outer surfaces of adjacent building elements. At least one flexible attachment portion extends from a lower surface of the cover portion, the at least one attachment portion including one or more interlocking elements. A track includes one or more grooves for receiving the attachment portion. One or more complementary interlocking elements are associated with each groove for retaining the attachment portion.
