Extensive Testing

InfiniteRule products undergo extensive third-party testing to determine shear strength. The shear strength is determined by placing the locking pin in a stress position and subjecting it to increasing force until a required proof load (maximum force received without deformity) is met or the pin fails. These locks have a shear strength of 42,000 lbs.

Heavy Duty lock for my new Rugged Aluminum Tandem Trailer. First time for a Demco brand coupler. Other trailer locks do not work. Thank you, etrailer for all of my Camper, Boat, Utilty and Car hauler trailer needs.

Goes on easy just as the excellent etrailer instructional video demonstrates. Haven't had anyone try to steal the trailer yet so guess it works fine.
