An elongate profiled section element for a mounting system includes a bottom, a top section opposite the bottom, and sidewalls extending from the bottom to the top section. The top section includes two flanges which extend from the side walls and delimit between them a longitudinal slot. The top section has a smaller width than the bottom. At least one of the side walls is a stepped sidewall having a stepped shape seen in cross section. The stepped sidewall has two wall sections facing the opposite sidewall and an intermediate wall section substantially parallel to the bottom. The intermediate wall section is provided with a row of holes and the bottom is provided with a row of holes aligned therewith, said holes being adapted to cooperate with a self tapping screw.

A valve rod isolation apparatus for reducing valve rod exposure to moisture and debris in a subsurface environment, wherein the valve rod is housed within an isolation sleeve that is sealed top and bottom.

A reusable drywall air injector is fashioned from durable, rigid material. A pointed tip for piercing drywall extends from a hollow cylinder around which is disposed a helical blade. A hollow hex section is connected between the hollow cylinder and a hollow nipple, the interiors of the cylinder, the hex section and the nipple interconnecting to form a path for compressed air. Embodiments of the injector further fashion the interior of the hollow cylinder with notches adapted to receive a driver head. The injector is inserted into drywall by driving the injector by means of a motorized drill or screwdriver engaging the injector either by deep well socket around the hex section or, in embodiments, by appropriate driver head engaging the cooperating notches in the hollow cylinder. After use, the injector may be removed from drywall for reuse by the same means operated in reverse.

A clamping assembly for supporting a tubular object accessing a through-hole in a panel includes a clamp and a retainer configured to be positioned at least partially around the tubular object on a first side and a second side, respectively, of the through-hole. The clamp and retainer respectively include at least one clamp lock mechanism and at least one retainer lock mechanism configured to move between a respective open position and a respective closed position. The clamp includes at least one clamp hook configured to engage with the at least one retainer hole in the retainer in a snap-fit relation when the clamp and the retainer are in the respective closed position at the first side and second side, respectively, of the through-hole. A method of supporting a tubular object and an aircraft having the clamping assembly are also disclosed.
