I am trying to find a lock that will fit through the bottom of the surge coupler where the hitch pin goes. It has to be at least 3 inches long. I tried a few but they come up short or are to big in diameter to fit the hole.
A brand or part # would be helpful.

Thanks,
Cordell

Take a look here http://www.hiddenhitch.com/Home/

Do a search on part # 28012......see if that is what you are looking for. It has a span of 3 3/8".

Let me know if you think that will work for you. If you can't find it locally give me a call and I'll have one shipped directly from my warehouse to your front door.

Thanks Buck,
I think that will do it. My coupler does not have the lever on the top like the picture but it should fit the span of the coupler on the bottom.

I checked with a marine store in the area today and they had a similar style by a company called Trimax PN # 255-TC3.

Once again thanks for your help and if I can not get one local or have a problem I will contact you.

I have the Yellow universal lock, (don't have the coupler Eagle uses), but you may can get it to fit (when not hitched to truck).

Not sure if you are looking to secure the coupler to your truck, or just make it harder to steal when boat is parked. I keep two locks on my coupler, and lock the fence to my backyard.
