Review on 🔒 CZC AUTO Hitch Clamp: Heavy Duty Anti-Rattle Stabilizer for Trailers, SUVs, Trucks, Vans, and RVs - Efficient Hitch Tightener Clamp for Cargo Carriers, Bike Racks, and Ball Mounts by Ryan Thrasher

This is an excellent product that holds the clutch securely. Each side has 2 nuts for extra security. I gave it a 4/5 because of the tensioner's misinformation. The metal of the U-bolt is 7/16" in diameter, not 8/16" (1/2"). I assume they counted the rubber cover as part of the diameter. .The nut is not 15/16” or even 14/16” (7/8”). I'm assuming it really is 22mm, but I don't have a 22mm wrench to check.
