Question:
Hi - Im looking for a trailer coupler latch lock. I have a Demco DA70 surge brake actuator for 2 ball installed. I saw you offer item IR66FR InfiniteRule lock. Is this the correct lock for my coupler? I saw in the notes for the lock that it is for cast, not stamped couplers. The DA70 is stamped. Otherwise, I liked the lock. I could not see another InfiniteRule lock that might work. What do you recommend? Previous customer here. Thank you!

Hi Frank; I'm sorry to say the # IR66FR is not compatible with your Demco Hydraulic Brake Actuator # DM72VR since it is stamped and not cast. For whatever reason they don't have a different version for that Demco coupler style. You will have to stick with a standard pin lock like # e98888 or get a surround lock like the BulletProof Hitches Extreme Duty Coupler Lock # BPH96VR. I like the surround style since it takes more work for your average thief to defeat it.
What kind of trailer do you have? Thanks for being a loyal customer!
