Review on Enhanced Trailer Coupler and U-Lock: Trimax UMAX50D Universal Dual Purpose by Steve Wynn

The best tongue lock ever used! Very impressed and the customer service is great. I have a Reese with a 2 5/16 tongue and it does the job but it's a monster. The lock has a chamfer, making it impossible to hit it hard with a hammer. The clip is twice as thick as the Reese and unlike the Reese has teeth on both sides. This lock is heavy and I'm sure my followers will be safe. Installs on 2 5/16 cargo trailers and 2 5/16 travel trailers. CUSTOMER SERVICE EXCEEDED EXPECTATIONS! I ordered 2 locks and they sent the locks with matching keys and delivery was quick.
