A framing system includes a first connection assembly that engages with a substrate. The first connection assembly includes a first connector and a track. At least one spring flange defined by the first connector engages with a fastener positioned along the substrate to maintain the first connection assembly in a fixed position relative to the substrate and to interconnect the substrate with the track. The framing system further includes a second connection assembly defining a second connector engaged to a stud. The second connection assembly engages with the first connection assembly to interconnect the stud with the track.

A clamping apparatus for an antenna includes: an arm unit coupled to a support pole and extending in one horizontal direction from the support pole by a predetermined distance; a common coupling unit detachably mounted to a front end of the arm unit by insertion and detachment operations of a coupling shaft elongated vertically, the common coupling unit being selectively rotatable from side to side about the coupling shaft; a rotation unit having a front end detachably mounted to a front end of the coupling unit by insertion and detachment operations of a rotary shaft elongated vertically, the rotation unit being rotatable from side to side by a predetermined angle about the rotary shaft; and a tilting unit coupled to the front end of the rotation unit to be tiltable vertically, an antenna device being coupled to the tilting unit.

An attachment device for attaching to a structural component of a building to couple a fitting to the structural component.

Disclosed herein is a holding means provided with a spacer capable of occupying a space between an upper horizontal part and an upper vertical part of a hanger and a nut.

Example aspects of a stiffening system for a hanger assembly, a hanger assembly, and method of reinforcing a hanger assembly are disclosed. The stiffening system for a hanger assembly can comprise a stiffener rod; a brace member oriented parallel to the stiffener rod; a stiffening connector coupling the brace member to the stiffener rod, the stiffening connector defining a connector hook and a fastener hole, the connector hook defining a hook recess, a portion of the brace member received in the hook recess; and a connector fastener extending through the fastener hole, the connector fastener pressing the stiffener rod into a corner region defined between the brace member and the stiffening connector.

An adapter includes a housing and a shaft receiving port defined in the housing. The shaft receiving port defines grooves extending at least partway along the shaft receiving port. The grooves include a set of first grooves and a set of second grooves, where at least one of the first grooves is different from at least one of the second grooves. Another adapter for coupling a device to a track includes a housing defining a threaded port and a shaft receiving port; a track retention arrangement including a foot and a threaded post extending from the foot, where the threaded post is rotatably engaged with the threaded port of the housing to raise or lower the foot relative to the housing; and a locking mechanism including an actuator and a plunger coupled to the actuator and configured to extend from the housing into the track channel of the track.

The friction clamp includes a cylindrical body of elongate form between ends and with a slot into which a tubular item is snapped. Lateral connectors such as a receiver with a cylindrical recess therein receive an end of a tubular member, such as a member similar to that which snaps into the slot. As an alternative to the receiver, a tab is provided extending from the clamp laterally. The tab includes a hole through which hardware is placed, and an item having a similar tab is placed adjacent to the tab extending from the clamp and the hardware tightened for fixation at a desired rotational orientation. As another alternative to the receiver, a small friction clamp connector is provided on an exterior of the friction clamp. A small rod (or other item) snaps into the small clamp. The small clamp and rod can be provided separate from the friction clamp.

Stacking storage arrangement including at least one container receiving space: a loading space which is arranged below the container receiving space: a frame assembly between the container receiving space and the loading space; and an upright on at least one corner of the container receiving space, which is connected to the frame assembly by at least one connecting device. The connecting device bridges an angle between the frame assembly and the upright and abuts the frame assembly in a clamping manner.

Block stacking arrangement that includes a plurality of container receiving slots, a loading space arranged below the container receiving slots in a direction of gravity, a pass-through opening between respective container receiving slots and the loading space, and a holding device, which is arranged in the pass-through opening, having a flap pivotable about a shaft between a holding position and a release position. The shaft is mounted in an edge of the pass-through opening, and the shaft is mounted at at least one end in a bolt socket that is upwardly open in the direction of gravity. The block stacking arrangement further includes a shaft hold-down device, which is fastened to the edge of the pass-through opening, arranged at least partially above the bolt socket in the direction of gravity to act on the end of the shaft.

A Hock stacking arrangement includes multiple container holding spaces; a loading space arranged below the container holding spaces; and a frame arrangement between the container holding spaces and the loading space, The frame arrangement has node elements that are arranged at corners of the container holding spaces, and each pair of two adjacent node elements is releasably connected by a same beam.
