Abstract: The disclosure concerns a coupling assembly comprising at least first coupler, a second coupler, locators which assist in properly aligning the couplers, and hardware to hold the two couplers together. The coupling assembly may have more than one coupler. One end of each coupler is configured to attach to an assembly member. Another end of each coupler is configured with a coupling mechanism such that it may be coupled to the coupling mechanism of another coupler. The interior side of each coupling mechanism may have one or more recesses called locator pockets. The locator pockets on one coupler are configured to line up with the locator pockets on another coupler. As the first and second couplers are brought into an aligned position, a locator may be placed into the void created by each aligned locator pocket pair. After the locators are inserted and the couplers are brought into approximate alignment, the user may insert bolts through the couplers and apply nuts to the bolts.
