Review on 🔒 Secure Your Trailer with the Trimax THPXL Hockey Puck Internal Shackle Lock - Rekeyable for Added Convenience by Joel Young

Looks like a very secure lock. I don't know how that proves. Paired with the Blaylock T33 it seems like a seriously impressive setup that only a reasonable (but not cheap) angle grinder can beat. Additionally, shims have been added on each side to prevent sagging of the pins. Also, a piece of 3/4" steel pipe was added down the middle. Between the washers and the pipe, it removes the gap to keep the hacksaw blade from falling on the pin and strengthens the whole structure.
