An expansion bolt and pivot and swivel mechanism therefor. The expansion bolt may have a base and a plurality of radially spreadable elongate elastic members cantileveredly projecting from the base at respective points of joinder to the base and terminating in respective spoons at respective points of joinder of the spoons, wherein the elongate elastic members have respective radially defined thicknesses at the points of joinder to the base that are substantially less than the corresponding thicknesses of the base, and respective radially defined thicknesses at the points of joinder of the spoons that are substantially less than the corresponding thicknesses of the spoons. The pivot and swivel mechanism may have a ring element that includes two spaced apart leg members having foot portions that turn to extend toward each other, the foot portions having respective, spaced-apart relatively enlarged ends; a swivel housing element having an open end for receiving and at least partially containing the ends of the foot portions so that the ring element can be substantially freely rotated about a pivot axis; and a capping element adapted for interlocking with the open end of the swivel housing element, the capping element having a bottom surface portion of radial symmetry about a swivel axis that is distinct from the pivot axis.

A tensioning tool having a body and two hooks. One hook extends radially outward from the body and the second hook extends tangentially of the body. The body has a grip opening extending through the body and a throughhole extending through the body. A tensioning system comprising the tensioning tool and two cords. One cord passes through the throughhole in the body of the tensioning tool and the second cord is secured in the first hook of the tensioning tool.

An eye-bolt assembly includes an eye bolt and a base portion. The eye bolt includes a ring portion, a stem portion, and at least one winged extension. The ring portion is attached a first end of the stem portion. The at least one winged extension is attached to a second end of the stem portion. The base portion receives and securely locks the eye bolt therein. The base portion includes a collar and a platform secured to the collar. The collar forms a first aperture therein. The platform forms a second aperture therein. The platform includes a spring being located at least partially within the second aperture. A first end of the spring is attached to the platform. The second aperture formed in the platform is in spaced communication with the first aperture formed in the collar.

A carabiner includes a swivel loop and a body rotatably coupled to the swivel loop about a rotational axis. The body includes a spine having a spine axis that intersects the rotational axis at an intersection point disposed within the connection between the swivel loop and the body. The carabiner also includes a captive eye formed completely within the spine. The body and the captive eye being both rotatable relative to swivel loop.

The present invention prevents damage to the hoses and cables extending from a tractor to its trailer by providing a sling-like device being designed and configured to grasp, secure, and support such hoses to prevent their contact with the tractor and its trailer. The present invention comprising a length of polyester webbing having an upper fastener loop and a lower support loop. The lower support loop comprising an upward fold having a 180-degree twist and being designed and adapted to permit the insertion and passage of the upper fastener loop therethrough and thereby defining a pair of conduit support loops. The pair of conduit support loops being designed and configured to receive and graspingly support at least one tractor trailer hose or cable.

An anchoring device includes a track bar, a restricting member, and a locking device, wherein the track bar has a receiving groove. The restricting member is put into the receiving groove through open ends of the receiving groove. A width between a section of walls of the receiving groove and a width of a portion of the restricting member is greater than a width of a mouth of the receiving groove. The locking device includes a main body wherein a locking portion is disposed on the main body and is manipulatable to move between a first position and a second position. The main body slidably fits around the track bar. When the locking portion in the second position, the main body could slide to fit a flange of a fixture. After that, returns the locking portion back to the first position to fix the main body on the track bar.

A mounting bracket for attachment to a strut channel is presented herein. The mounting bracket includes an attachment structure and one or more mounting structures. The attachment structure includes at least two clips facing in laterally opposite directions and sized to fit within an opening of a strut channel. The clips can be moved or flexed upon application of appropriate squeezing or inward forces exerted upon the mounting bracket. When the mounting bracket is attached to the strut channel, at least one of the mounting structures is positioned at least partially within the strut channel interior.

A protective key is provided for placing distance between a user and a touch surface or handle, thereby avoiding direct contact between the user's skin and the touch or grab surface. The protective key helps protect the user from exposure to viruses or bacteria that ay be present on the touch or grab surface, The protective key can be formed of an antimicrobial material that resists accumulation of viruses and bacteria.
