Question:
Very pleased with the quickness of the response. I inadvertently ID’d my coupler as a trigger latch but it is a yoke latch. I did include a pic with my question but don’t know if the pic was clear enough to show the difference. I have tried a fast max type lock but it doesn’t seem to fit very tight. I was wondering if the master lock that slides over the front of the coupler would work?

Expert Reply:
Do you have a photo of your trailer coupler? If it looks like the A-Frame Coupler part # CA5100B then yes, the Master Lock Heavy-Duty Coupler and Latch Lock Combo part # 3784DAT should work for you as that is what it is primarily designed to fit.
I have attached a review video on a straight trailer coupler but it will also work on a-frame trailer couplers as well.
