If the piece of sealtight is leaving the disco and is not in use. It should be removed. I agree with John that those clamps here in NJ is called Cowboy clamps. The reason they were called that ( As I was told) was because the looked like a spur on a cowboys boot. Go figure that one from Jersey? If the Sealtight is UL listed for UV and protection from physical damage, Then maybe you would have to pass that job. Is it sloppy? Yes, Proper Workmanship like install? No!
