A closure device having a lock element that can be locked on a mating piece, preferably for closing a sealing flap of an opening, in particular an inspection flap, preferably in a drywall construction, in particular for a wall or a ceiling is provided. A closure device is distinguished by the fact that the lock element is arranged in such a way that, preferably under the action of a spring, in a first position with respect to the mating piece it is or can be moved into a locking position and, in a second position, it reaches a position and/or a state without any blocking action.

There is provided an access panel for releasably covering an aperture in a structure, the access panel including a panel member having inner and outer sides, and a panel stop extending from said inner side. The access panel includes a mounting member attached to the inner side adjacent a first edge to engage the structure. The access panel also includes a movable clip member slidably mounted on the panel member. The clip member comprises a casing and a mounting flange secured to a first end of the casing. The casing is linearly movable over the panel stop. The mounting flange is adapted to engage the structure proximate an opposed second edge of the panel member. The access panel also includes a spring situated within the casing between the first end of the casing and the panel stop for biasing the clip member toward the second edge in use.

A building is constructed by providing a subfloor and forming a hole in the subfloor. A hole protector includes a cylinder, a skirt disposed around the cylinder, and a cap disposed on the cylinder. The hole protector is disposed over the hole with the cylinder extending into the hole. The hole protector is fastened to the subfloor. The cap is removed from the hole protector. An MPE is disposed through the cylinder.

A method is provided for mounting an item of furniture, and in particular a cabinet, in a cavity formed in wall cladding. The arrangement is such that part of the item of furniture is held against an outer surface of the cladding by fixing elements that are displaced into engagement with an inner face of the wall cladding. The fixing elements are displaced into position from the interior of the cabinet.

A system for interfacing a floor vent to floating flooring. The flooring is for covering a floor and the floor vent is for covering a hole through the floor. The system includes an underlayment for placement on the floor, the underlayment having a first compressibility; a floor vent for placement over the hole through the floor; a flooring material for placement on the underlayment, the flooring material having a second compressibility that is substantially less than the first compressibility; and an interface structure for placement on the floor, adjacent to the underlayment, beneath portions of the floor vent, and beneath portions of the flooring material adjacent to the floor vent, the interface structure having a third compressibility that is substantially less than the first compressibility.

A container is described herein that is configured to be mounted between joists in a substrate of a structure, such as a floor, wall, or ceiling. The container includes a body portion sized to be disposed between the joists and a lid to cover an opening to the body. The lid can further be configured to be coplanar with a covering material of the substrate so that the container does not project outwardly from the substrate.
