A support rail and housing assembly is mountable on a housing base. The housings are equipped with electrical contact and/or functional elements which can be strung together. The support rail is mountable on the mounting base even when the housings have already been arranged on the support rail before the support rail is mounted. The support rail is secured to the mounting base by two or more mounting pins which have been placed before the support rail is mounted to the mounting base. The mounting pins and the support rail are designed to correspond to each other such that the support rail can be placed on the mounting pins and locked thereto without using a tool.

Systems and methods are provided for securing aircraft sidewall. One embodiment comprises a hanger for supporting sections of sidewall for an aircraft. The hanger includes an elongated vertical member that attaches to a frame of the aircraft, and sets of keyholes that are each arranged in a vertical pattern along the member and that are each configured to support a corresponding section of sidewall of the aircraft. Each keyhole includes a receptacle dimensioned to receive a fitting from a section of sidewall, and a slot dimensioned to slidably accept the fitting via the receptacle to secure the fitting in place. The slot size of keyholes in each set varies from one end of the vertical pattern to another end of the vertical pattern.

A fastening device for fastening an element in a keyhole-shaped cutout in a wall includes a retaining element which in the fastened state of the fastening device is designed to rest against a front side of the wall, and to at least partially cover an edge of a narrower opening of the key-shaped section in a wall. The fastening device also includes a support element which in the fastened state of the fastening device is designed to engage through a wider opening of the keyhole-shaped cutout in the wall, and to support the fastening device against a lateral edge of the wider opening during fastening.

A device for securing a pipe to a wall, including an exterior wall of a building, is provided. The device has a generally flat surface which adheres to the wall and a generally curved support unit which receives the pipe. An optional securing bar may be locked over the top of the pipe to prevent movement of the pipe. In an embodiment, the device has an extension flange which allows the pipe to be secured to the wall in an off-set manner. Preferably, a plurality of the present aligned devices secure the pipe to the wall in a horizontal or vertical manner. The device allows the pipe to be secured to a wall in compliance with governmental regulations. An adapter unit may be inserted over the curved support unit for one or more smaller pipes.

A method of joining panels is disclosed, including adhesively bonding a case in a slot of a first panel, the case having a channel on an inner side, and adhesively bonding a plate to a tab portion of a second panel, the plate having an external pin member. The method further includes inserting the tab portion of the second panel into the case in the slot of the first panel and sliding the external pin member of the plate along the channel on the inner side of the case, to a locking position.

An angle bar includes two longitudinal angled plate portions, and a corner portion connecting therebetween. The corner portion has an inner corner surface bounding an inner corner space and an outer corner surface. A stopper protrudes into the indented corner space, and has an abutment face extending across the indented corner space. A limiter protrudes into the indented corner space from the inner corner surface, and has a through hole opening in a direction along a bending line of the corner portion. A modular post assembly has at least two angle bars abutting each other, and a fixing rod extending through the through holes of the bars along the bending line and limited between the stoppers for fixing together the bars.

A product for fastening a component in place may include a retainer connected with the component. The retainer may have a platform and may have a wall extending between the component and the platform. The platform may define an opening that may be configured for fastening. The wall may define a slot.

A marking apparatus facilitates blind mounting of an object to a mounting surface in a desired alignment using the object as an alignment template. One end of the apparatus is configured to be affixed to a mounting slot or edge of the object, then the other end used to mark the appropriate supporting fastener location on the mounting surface. The object's mounting slots or edges may be represented by mounting hardware components that are flush with, recessed in, or protruding from the local planar surface of the object. To accommodate a broad variety of mounting conditions and mounting hardware, certain embodiments of the apparatus may include selectively adjustable or interchangeable head adapters, distinct head and retention configurations and/or a hardware relief channel. A channel adapter is disclosed for use with embodiments of the apparatus having a hardware relief channel. Embodiments of a slot-securable point marking tool are also disclosed.
