Product Details

The Master Lock 377KA Universal Trailer Coupler Lock provides reliable theft protection for trailers with 1-7/8 inch and 2 inch couplers. This heavy-duty security lock features a durable steel construction with a weather-resistant silver finish designed to withstand outdoor elements.

Key Features:

  • Fits both 1-7/8 inch and 2 inch trailer couplers for universal compatibility
  • Hitch ball and clamp-type locking mechanism prevents coupler from attaching to towing vehicle
  • Keyed alike system allows multiple locks to operate with the same key (when purchased as a set)
  • Hardened steel construction resists cutting and sawing
  • Corrosion-resistant silver finish for long-lasting durability
  • Provides visible theft deterrent to protect trailers, boats, utility trailers, and RVs

This coupler lock is easy to install and remove, making it ideal for securing trailers when parked at home, storage facilities, or on the road. The keyed alike feature is particularly useful for trailer owners with multiple trailers or who want to use the same key across multiple Master Lock security products.

Fast and easy

Great buying experience

Quick fast and good

First time I've used your website - it worked out great! Thanks.

real pleased with the transaction

I was having difficulty finding EGR Fender Flares that were available, but Autoplicity not only had the exact set I needed but had them at the lowest price I'd seen and had super fast shipping - thank you Autoplicity!

Autoplicity has great prices and quality products for sale, I'd give it 1/2 star less for slow shipping given the option. Took a while to get out their door, regardless, I would still purchase again, thanks Autoplicity!

This is my first purchase. So far, it's going well.

No hassle ordering and fast quality shipping at a reasonable price
