## Description

Size:3KA-379-3




























Please check the width of your receiver tube. Standard 2" receivers are exactly 2 inches wide (inside) with 1/4" thick tubing walls. If your vehicle is standard this 1480KA receiver lock will fit. However there are receiver tubes that have extra thick walls. Some of the trucks with heavy duty tow packages and some trucks come standard with "doubler plates" welded onto the sides of the tube. If that is the case with your truck you will need the longer shaft 1469KA receiver lock that measures 3-1/2" long. You may request the longer lock via a message after the transaction. We will acknowledge your request so you can be sure your message is received.

## Features

- Complete trailer security. These locks will fit virtually all trailers that have 1-7/8", 2" or 2-5/16" couplers. Please check/read the SEE MORE PRODUCT DETAILS below for important receiver lock fitment information. Limited Lifetime Warranty on all locks in this set.
- KEYED ALIKE - One key opens all three locks. We can key multiple sets to the same key number. If multiples are ordered we will automatically key them all the same. Each lock comes with two keys, for a total of six keys.
- COUPLER LOCK FEATURES: This black coupler lock is very difficult to defeat, by virtue of how the top of the lock rests on the top of the coupler, withstanding downward forces. See second image. The lock will also rotate if hit hard, with no rigidity the lock is tougher to defeat. Advanced locking mechanism resists picking and prying. Simple installation and removal. Rekeyable cylinder for keyed alike convenience.
- RECEIVER LOCK 1480KA FEATURES: Protects from theft when securing the ball mount to the receiver. The lock features the NEW Push To Lock Security. Push lock body onto pin firmly and remove key. Stainless Steel for ultimate corrosion resistance. Water tight cap protects lock. Solid brass lock cylinder and aluminum cylinder case offer extreme corrosion resistance. 5/8 diameter pin fits 2in receiver tubes, Class III/IV. 10,000 lb load rated. The shaft's length is exactly 2-3/4 long.
- LATCH PADLOCK FEATURES: 1-9/16 (40mm) wide laminated steel body, 9/32 thick hardened steel shackle for extra cut resistance. Thousands of key changes maximize key integrity. Dual Locking levers provide extra pry resistance. Proprietary rustproofing for longer life. HARDENED steel bottom plates for drill resistance.

### ⭐⭐⭐⭐⭐ 







  
  
    This is well made, and a good deterrence
  

*by B***M on Reviewed in the United States on August 5, 2019*

I ordered a new boat trailer so I ordered this set to help me secure it.  Once the trailer came, it was much too wide for this latch lock ... but that does not affect my rating as I would have known better if I had seen the trailer.  The picture shows the difference between three popular latch locks.  This latch lock fits my other trailers and I would give it Five Stars for it's intended application.I think the manufacturer anticipated that their kit could wind up split up, mix and match, as it includes six identical keys.  I use this on my log splitter, so it's nice to have a separate set of keys for it.The receiver lock was much better than my old one on my truck so I used that.  It seems very well made and the lock is protected from salt, and road grime.  It is easy to use.The ball lock seems very sturdy, made of first rate materials, and easy to install.  It looks formidable ... which is all that matters since NOTHING you can do will thwart a serious thief.  I'm perfectly satisfied with this set.The

    Poor fit.
  

*by R***S on Reviewed in the United States on July 20, 2020*

Only one of three locks fit.  My hitch pin lock was too short, the latch pin padlock wouldn’t fit.  The lock that did fit, the hitch receiver, seams kinda cheap.  Seller did everything right, and product may work for some, but only one in three locks work with my grand design.

### ⭐⭐⭐⭐⭐ 







  
  
    Perfect Combination
  

*by G***E on Reviewed in the United States on November 4, 2018*

The best part of this Combination is that it makes perfect sense and all of the locks are keyed the same. I needed a receiver lock for my new truck, a trailer lock for when it's parked outside, and a padlock for when my trailer is hooked up to my truck. It was easy to rekey several other Master Locks that I have, and I love having 6 identical keys (included in the set) that fit most of my locks.  Unfortunately my larger Master Locks don't fit the key-way which makes it impossible to key the same.
