The big brother to the 377, the Master 378 is a sturdy trailer coupler lock and remains a popular part of Master Lock's towing line. Please don't buy it thinking it will fit your 2-5/16" gooseneck trailer unless you have tried your neighbor's and are sure that it fits!!
NOTE: Master Lock no longer offers this lock in keyed-alike. Sorry. It is not rekeyable.
