BOWDOWN ELBOW

I have had this product for several years. Yesterday a semi-truck driver saved me and maybe some others from disaster. He blew his horn several times while passing on a busy interstate and it gave me cause for concern so I looked at the kayak on the right side of the car and the nose was hanging out probably 2 ft off the side of the car. I pulled over and strapped it down a bit more so all ok. But what happened was the piece with the tightening screw broke at some point so the rack collapsed. It was still tied down on front and back but doubt things would have held together much longer.

I can buy a replacement part I see but I no longer trust this product. (Both a good and bad picture)
