Question:

Hi. I would like to know if you offer a coupler lock that will allow for multiples to be ordered and keyed alike. We have a 4 trailers with same or similar hole widths and would like coupler locks for them. We have Proven locks for when they are off of the vehicles, but they are used for Disaster Relief and travel all over the southeast so we would like some even minmal protection while attached to the trucks. They would have to be keyed alike however. Thanks.

Hey Ken, thanks for reaching out and for helping out with disaster relief!

For your application I recommend picking up the etrailer Surge Brake Coupler Lock which will work well in either the 2" # e98886 or 2-1/2" # e98887 span configuration. This pin has a 1/4" diameter so you just need to verify that the pin hole this needs to fit into will allow the 1/4" dimension and you'll be good to go!

Just be sure to select the "keyed alike" option and how many you want prior to checkout, and we will get them sent to you.

Is this the type of lock you were thinking of using?

Thanks for clarifying that for me. I will be ordering some as soon as I can verify width on each of our trailers. I really appreciate the quick response!
