How to Install a Master Lock Universal Heavy-Duty Coupler Lock


Alright today on this Gooseneck Trailer were going to do a test fit of part number 2989at from Master Lock, this is their universal heavy duty coupler lock. This lock will work on the Gooseneck Trailer as shown here and also on the fifth wheel. The lock comes packaged with the adapter for the fifth wheel in place, but we dont need that for our Goosenecks, were just going to take it and slide it out and remove it. Take the lock, this half will go up over the latch, just slide it up over the top of it, and the other half will slide over the other side. Basically squeeze it together, and we will take the key on the side and lock it. In a couple of steps our lock is already installed on the cup link.

Alright and with that it will finish it for our test fit of part number 2989at from Master Lock, the fifth wheel Gooseneck coupler lock. .
