The IronRidge UFO Stopper Sleeve allows you to convert the UFO into an end clamp. It is also available in clear and black finish to match the rest of the racking system and your solar panel frame color. The Stopper Sleeve comes in 6 sizes to accommodate solar panels with frames ranging from 30mm to 48mm in thickness.
The UFO clamps simplify the amount of hardware needed for your solar installation. It comes preassembled with a grounding washer, creating a bonding point with each attachment and a consistent grounding connection across the solar array.
IronRidge’s integrated grounding system is UL2703 listed. All the parts of the racking system, are mechanically and electrically bonded together. The entire solar array, including the solar panels and all racking components, is grounded with one single lug.
Use the table below to select the part number of the stopper sleeve required in your project. The right size depends on the thickness of the solar panel’s aluminum frame.
