Features to know about
Locks the Latch While Your Trailer Sits
Parking or storing your trailer leaves the coupler latch exposed. This lock passes through the latch on your Dexter Drop-N-Go auto latch coupler and keeps it secured, adding a theft deterrent while your trailer stays unattended.
One Key Pattern across Multiple Locks
Carrying separate keys for every trailer lock gets cumbersome. The keyed-alike design can match other InfiniteRule locks, keeping your trailer security hardware on the same key pattern.
Stainless Steel for Outdoor Storage
Your coupler lock stays exposed to rain, road spray, and moisture around boat ramps. Stainless steel resists rust and corrosion, keeping the lock suited to boat trailers, utility trailers, and other trailers stored outside.

This product was as advertised and fit nicely on my 2 5/16” coupler. There weren’t any instructions included with it but it was pretty straightforward to figure out how to install it. I am looking forward to using it the next time I go fishing.

Fit just as I expected after taking a measurement and after looking at most 1/4” pin locks for sale, I think this one is the most robust

Love it! It’s solid and well made. Just make sure you order the right span length for your trailer lock. I paired it with the Bulletproof Hitch lock. My trailer is safe!

Pior to purchasing this lock from etailer I bought several competitive trailer lockks from big box stores. All were junk compared to this one. I was hesitatnt to purchase when I saw the price but I would have saved a lot of money and disappointment had I purchased this one first. I will not stop a very determined thief with power tools but ti is far superior to anything else I tried.

I had a similar type coupler lock on my utility trailer that had begun to corrode because it was not made of stainless steel. I am using this one on my new vacation trailer along with an extreme duty coupler lock.

I searched everywhere for something like this. I like that it's nice and hefty and seems like it will be secure. I have the new Wallace Forge coupler on my RV which requires a wider span than the smaller one's. This fits my coupler but I do have one complaint. The pin is only 1/4 inch diameter and my coupler has a much larger hole but your site did not carry the larger pin, so I had to settle. If you have the larger pin I would be happy to exchange the 1/4 inch pin.

Even tho this wound up not working with my trailer, the lock seems well built and sturdy. Maybe I'll find a use for it down the road.

The coupler functions as advertised. Ease of installation and a visual deterrence for “courious” passersby. I would definitely recommend this lock.

It looks like it’s a nicely built tongue lock system. When it was delivered and I opened it, the finish was already scratched. Kind of strange, as it was packaged nicely. Should also be a great visual deterrent.

Although the lock was expensive, it will be extremely tough to remove without a key. It's exactly what I needed to protect my trailer from theft.

- Recommended Lock for Dexter DX6.6 Drop-N-Go Brake ActuatorHey Mike, sorry for the delay on this. For a lock I recommend the InfiniteRule Trailer Latch Lock for Dexter Drop-N-Go Auto Latch Couplers # IR39RR. This is specifically designed for your Dexter DX6.6 Drop-N-Go # DX29UR (same as K99-066-20). I knew they made a lock for this, and it was the best option, we were just waiting for InfiniteRule to get it added.
