Saves Time
We've installed a few systems using these Top Mounting Clamps. Overall, they save that critical "dangling from the roof" time. The only negative comment I have with these is that the anchor bolt can be very frustrating since the "catching" angle can easily slip if it turns even slightly CCW. We've considered replacing these bolts Unirac sends with standard 1/4" SS bolts that just slide down the rail slot.
