Abstract: A rigging system adaptor which creates an infinite number of adjustability positions for a line array, wherein the adaptor is particularly well suited for use with a spine frame. The adaptor comprises a main frame having a longitudinally extending body to which a first attachment member, a second attachment member, and a mount are attached. The first attachment member may be fixed onto the main frame via a pair of lateral rods, wherein the lateral rods are oppositely situated from each other relative to the main frame. The second attachment member and the mount may be slidably engaged with the lateral rods such that they can move along the main frame and can be repositioned to meet the specific needs of a user.

Abstract: Disclosed herein is a linear adjustment device for altering the position of a load comprising, wherein the linear adjustment device comprises a positioning mechanism comprising: a rod; a first pipe slidably engaged with the rod; and a second pipe slidably engaged with the rod. The linear adjustment device further comprises a load sleeve, wherein the load sleeve is secured to the first pipe; and an anchor sleeve, wherein the anchor sleeve is secured to the second pipe. Further disclosed herein is a system incorporating the linear adjustment device disclosed herein, and a method of use.

Abstract: Disclosed herein is a structural element comprising a longitudinal vertical component and a longitudinal horizontal component extending from and parallel to the longitudinal vertical component. The longitudinal vertical component comprises a top side joined to a discontinuous bottom side by a first and second end wherein the discontinuous bottom side comprises a first portion and a second portion separated by a cavity. The longitudinal horizontal component comprises a distal end comprising a shoulder, wherein the shoulder extends through the cavity. Further disclosed herein is a load suspension device comprising two structural elements as disclosed above joined by an axle.

Abstract: Disclosed is a device for suspending loads that also allows for adjustment and focusing of the load at desired elevation and azimuth angles. The device can be used interchangeably with loads of various geometric attributes because it is designed to operate based on a load's center of gravity. Furthermore, the device has linear control function to enable easy and precise focusing of the elevation of the load.
