Product Details

The Master Lock 379KAATPY Universal Coupler Lock provides reliable theft protection for your trailer, RV, or boat trailer when parked or stored. This versatile lock is designed to fit both 1-7/8 inch and 2 inch couplers, making it compatible with most standard trailers.

Key Features:

  • Universal fit for 1-7/8 inch and 2 inch trailer couplers
  • Durable steel construction with chrome-plated finish for corrosion resistance
  • Easy installation requires no tools
  • Prevents unauthorized hitching and trailer theft
  • Weather-resistant design for outdoor storage

This coupler lock works by inserting into the coupler throat and preventing the ball mount from being inserted, effectively securing your trailer against theft. The chrome plating provides long-lasting protection against the elements while maintaining a professional appearance.

Fast shipping and great prices will do business again (actually really soon)

Very straight forward and easy to navigate website

I did my homework on what fuel pump to buy, and even more homework on who to buy it from. Autoplicity had the best price including shipping of everythere I looked, and were quick to answer the phone confirming they indeed had the part in stock to ship. It was sent within 24 hours of placing the order.<br><br>I'd definitely buy from them again.

I found them doing a search for a clutch kit, they are hands down one of the easiest companys to work with and the prices cant be beat..... I looked everywhere

Ordered a Dee Zee bed mat for my truck. Got it right away and it fits like a glove!!!

Order an item a day ago and the next day its shipped! Had a question and customer service was there when you needed it!

Autoplicity gave me prompt notification both when my order was processed and when the order shipped. The price was the best I could find anywhere, and several good reviews made me confident in my choice of stores over other stores who were charging more. Thanks, Autoplicity!

Low prices, Fast shipping and great service!

Definitely fast processing and shipping as well as very great low low prices
