Coupler Lock and Coupler Pin Lock Needed to Replace 3/8 x 3-1/8 Pin

Question:

I have a new boat trailer and it has a different hitch than Ive seen before. I can send a picture. I need a hitch lock and a pin that locks. The pin is 3/8 by 3 1/8 but the hitch doesnt have a lip so most locks wont work.

Thank you for the picture!

One of the most accommodating coupler locks that we have is the Fastway Universal Trailer Coupler Lock # FA86-0015-316 which fits 1-7/8", 2" and 2-5/16" size couplers. If you check out the pictures on the product page you can see that it fits a wide variety of coupler sizes and shapes.

Then for a coupler pin type lock we have the coupler lock# e98888 which has a pin diameter of 1/4" and has an inside span of 3-3/8". It isn't the exact same size as your current pin but since it is a little longer and has a smaller diameter it will work correctly.

I have linked review videos for both locks for you to check out.
