A concrete anchor capable of resisting large loads while requiring minimal embedment depth. The system includes a concrete structure including a cylindrical opening in the concrete surface thereof. The system also uses an anchor which includes a sleeve and a plug. The sleeve includes at least two legs extending toward a first end of the sleeve. The plug includes an increasing diameter portion disposed toward a first end of the plug. The plug includes a locking opening. After installation, legs of the sleeve extend radially outward past the wall and the increasing diameter portion prevents inward movement of the legs to lock the sleeve and the plug in turn in the concrete cylindrical opening. Furthermore, dynamic loading on the plug via the locking opening when the anchor is in use generates a dynamic radially outward force on the legs to secure the anchor in the concrete hole.

Curtain hook assemblies are disclosed that include backing plates secured to a curtain and curtain hooks rotatably mounted on the backing plates. The curtain hooks can rotate from flat positions against the curtain during packaging to extended positions for hanging on a curtain rod. A lower hook may optionally be integrally or rotatably attached to the backing plate.

A modular safety fence assembly is disclosed. The safety fence may include a fence panel assembly having a top rail, a bottom rail, and mesh panel. The safety fence panel assembly may also support post assembly capable of supporting the fence panel assembly and an anchor assembly which may anchor the support post assembly to the floor using one or more relatively shallow holes formed in the floor.

The present disclosure relates to an insert and system of installing the same. The insert includes a tapered core and a cylinder. The core releasably secures to an installation device which includes a depth stop or a depth control to control the installation depth of the insert. The insert may be provided in a tray that allows for easier handling of the inserts and installation thereof in installation holes, for example in a hydraulic manifold. In some cases, the core includes a threaded hole to releasably secure the insert to the installation device, thus allowing the installation device to pull the core into the cylinder. The core and cylinder may be made of metallic materials such as steels, steel alloys and others. In some cases the insert can withstand blow out pressures of 40,000 psi or higher.

A device has two anchor sleeves (3) in a concrete wall (2) accommodating two parallel anchor bolts (6) of a U-shaped step iron (1) form-fittingly. Between coupling parts formed by the anchor sleeves (3) and the anchor bolts (6), a detent assembly (7) has at least one detent tongue (8) sprung in the radial direction on one of the coupling parts (3, 6) and a detent recess (9) that receives the detent tongue (8) on the other coupling part (6, 3). A guide surface (15) for the detent tongue (8) is inclined in the peripheral direction and extends in the radial direction over the engagement depth of the detent tongue (8) adjoining the detent recess (9) at least in a peripheral direction.

A fitting assembly includes a jaw fitting comprising a body, a first jaw extending from the body, and a second jaw extending from the body, the first jaw oriented substantially parallel to the second jaw, the jaw fitting defining a bore formed through the body and a hole formed through the first jaw, the jaw fitting further defining a slot between the first jaw and second jaw; a first fastener engaged with the hole and extending into the slot, the first fastener configured to couple a brace member to the jaw fitting; and a second fastener defining a tail end engaged with the bore, the second fastener repositionable relative to the jaw fitting to adjust a length of the fitting assembly, wherein the second fastener is oriented perpendicular to the first fastener.

A metal collar attached in a through-hole of FRP member includes first and second collar members. The first collar member includes outer and inner circumferential surfaces. The outer circumferential surface is in contact with a hole inner circumferential surface of the through-hole. A slit is formed in a part in a circumferential direction of the first collar member. The second collar member applies a pressing force radially outward to at least a part of the inner circumferential surface of the first collar member or a pressing force to inner surfaces of the slit in a direction in which the inner surfaces separate from each other in the circumferential direction. The second collar member is held in the first collar member by reaction of the pressing force, deforms the first collar member for diameter expansion with the pressing force, and presses the outer circumferential surface against the hole inner circumferential surface.

A fitting assembly can include a socket fitting comprising an end wall and a substantially cylindrical sidewall extending from the end wall, the end wall and cylindrical sidewall defining a cylindrical interior recess, the cylindrical sidewall defining an open end opposite the end wall allowing access to the cylindrical interior recess, the cylindrical interior recess configured to receive a first end portion of a brace member, a bore formed through the end wall and a hole formed through the cylindrical sidewall; a first fastener engaged with the hole and extending into the cylindrical interior recess, the first fastener configured to couple the brace member to the socket fitting; and a second fastener defining a tail end engaged with the bore, the second fastener repositionable relative to the socket fitting to adjust a length of the fitting assembly, wherein the second fastener is oriented perpendicular to the first fastener.
