Attach the Stubby Keeper Plate at the top of the scenery directly in line with the Shackle Plate that you have bolted to the lowest point of the piece. The cable line used to suspend the scenery is attached to the Shackle Plate and then run though the Keeper Plate's eye opening and finally onto the suspending point.
Made from heavy-gauge steel and pre-drilled for assembly with two 1/4" bolts.
