Master Lock Hitch Receiver and Coupler Latch Lock Set - Swivel Design - 2" Hitches - 1481DAT

Average Customer Rating:  4.7 out of 5 stars   (203 Customer Reviews)

Convenient kit includes a flush-design, stainless steel trailer hitch receiver lock with an easy-to-use swivel head and a stainless steel latch lock for your trailer's coupler. Fits 2" x 2" hitches.


Out of three items I ordered, I only received the ball mount and lock, no ball.
The two items I did receive are well made and fit with no issues on my 2018 aftermarket hitch. The ball itself has not been shipped and the expected delivery date is over four weeks for delivery, so I can’t comment on it or the whole unit as a whole.
Terrible shipping , but quality ball mount and locks.


First order for a hitch and wiring kit arrived quickly. However, the wiring kit packaging looked damaged and was missing the main electrical adapter. Customer service was very helpful and shipped replacement harness quickly. Giving 4 stars for the original order being packed incomplete.


Work as intended


Excellent quality of products. Have shopped with more than once and will go there first for RV products. They have competitive prices also.


I think that master lock makes a great lock. I like that the hitch receiver & coupler latch lock is stainless steel & won't rust. I will be using the locks when I am pulling my UTV trailer. And now I have less keys to carry. I would recommend this combo lock set to anyone.

Lavern H.


My stainless steal Master Locks for my receiver hitch & trailer hitch lock are still working great for me. I like that I only need 1 key for both locks. Im loving my locks.


Great locks for the hitch and coupler, made to last.


Excellent product and excellent service. The product arrived sooner than expected and that is really appreciated. I will be ordering an aluminum ball mount soon as I like the hitch and all accessories to be as rust resistant as possible and the ball mount as light as possible. Thank you very much

Joseph J.


The product is still in excellent condition and have had no problems.


1st time customer. Great experience start to finish. I really enjoyed "seeing" the people who made it happen on the shipping confirmation email. What a great way to honor the employees. I also want to provide positive feedback on how the order was packed using a high quality box designed for heavy items with convenient side knockouts for hand holds. So maybe the dozen or more staples securing the top was overkill (ended up cutting top off instead of pulling staples) but the package was 100% good condition when it arrived. I was also surprised and pleased how quickly it arrived. The tracking tool on the email was quick and convenient. I will be ordering again when I rehab a 5 x 10 landscape trailer I had custom built 25 years ago. Thanks!


Easy to use, matching keys, and easy access to the keyhole.

Greg Z.


I still have the Hidden Hitch ball mount and the Master Lock locks. Theball mount is great. My only knock on the locks is the flimsy dust coverthat covers the key holes. The narrow strap that attaches them broke aftera few uses and the caps dont stay on well. I use a piece of duct tape oneach lock to keep the dust out, since Im often going down gravel or dirtroads with the trailer.


Michigan uses salt on their roads and this Master Lock is still working like the day I bought it. Our roads are some of the worst in the country with rusted out vehicles and things like that. It may not shine like a new penny, but its completely functional.


Works well and condition holding up.


Never used it...


So, the hitch receiver looks well made and makes a tight fit to reduce the chance of cutting.

The hitch lock on the other hand does not tighten up enough leaving the shaft exposed to a hack saw. Too bad.

Yes, you could get a hack-saw on the lock. The bar is solid 58 inch stainless steel. It can be cut with a hacksaw, but youll be there for a bit, and thieves dont usually hang around long.


I have ordered from them on a few occasions. Everytime, shipping is quick. Prices are reasonable.



It has been working perfectly well


Been using it for one year and it works great.


Does the job, easy to use, nice to have one less key to keep track of. I really like the sturdiness of the hitch lock. The coupler latch lock feels like it would be simple to break for the determined thief, but it serves its purpose as a deterrent for the casual criminal. The rubber lock cover was ineffective; after a night of rain, the lock had plenty of water in it under the cover. Probably best to point the lock towards the ground if you are concerned. But at this price, I don't expect it to last forever anyway.


Excellent packaging, delivery and overall satisfaction with the product and the service. Looks nice on my Hummer H2.


Piece of mind when parked outside. Easy to use.


A little difficult to lock at times.


Performed very well and still in good shape after towing light camping trailer over 10,000 miles on a 3 1/2 month trip. Lots of hitching/un-hitching. I found these easy to use and have been very pleased.


Perfect for protecting your hitch and your boat while connected to your vehicle. These both used together will lock your boat (trailer) to your vehicle.



Outstanding product. Still look and act like new. With these I know my trailer is secure to my hitch and my hitch is secure to my truck.


This product is stainless which its excellent for the hitch pin and lock as it's always outside in the weather. Both pin locks are keyed alike, simplifying locking & unlocking. I made the mistake of going with the cheapest shipping with the postal service. It took 10 days to get here. Otherwise everything was excellent.


This was perfect for my bass boat trailer, I lost the key to my old one and had to cut it off. This replacement was quick and easy, less than five minutes to install.
I used the bearing buddys on a flat bed trailer I just purchased, installed them in ten minutes and was back on the road. Great products and even greater service, Thanks etrailer !!


Quality of the product was great! It is difficult to lock if you have a cover in your reciever , and the O ring came off the second time I locked it!

I liked the keyed alike idea but you need 3 hands to use it.


Order was shipped quickly. Package was in excellent condition. Always a pleasure to due business with them. Thanks

  • Trailer Coupler and Hitch Lock Set for a 2013 Subaru Outback Wagon and A-Frame Trailer
    The Master Lock hitch and coupler lock set # 1481DAT includes a coupler lock (the smaller one) that would fit in a hole on a latch style coupler provided that hole is 1/4 inch in diameter (which is industry standard). With the lock in place whether towing or not towing, the latch cannot be opened so it could not come off the ball or be placed on a ball. I have included a picture that shows the hole in the coupler I mentioned. If you have a different type of coupler this type of lock may...

  • Is there a Weight Capacity for the Master Lock Hitch Receiver and Coupler Latch Lock Set
    Hitch pins and locks don't actually bear any of the weight of a trailer or accessory so they don't have weight ratings. The only weight capacities you need to consider are for the tow vehicle, the hitch, ball mount, and hitch ball. The tongue weight of a trailer puts so much downward force on the ball mount that it binds it up so well in the hitch that the hitch pin doesn't actually have any force put on it. The hitch or ball mount would fail before the hitch pin would. The pin hole for...

  • Is There a 3/8" Pin for a Coupler Latch Lock
    The pins used in the latch hole on a trailer coupler are not actually holding anything together. They are simply an anti-theft mechanism which stops anyone from being able to open the latch and either uncoupling or coupling the trailer with the pin left installed. I supposed they could also be looked at as a fail safe while out on the road as well. That said, the pins are all 1/4" so I think the manufacturer may have confused that part.

  • Comparing Master Lock Hitch Receiver and Coupler Latch Lock Sets
    The main difference between the Master Lock Hitch Receiver and Coupler Latch Lock Set part # 1481DAT and part # 2848DAT is that the former is for 2" hitches and the latter is for 1-1/4" and 2" since it comes with both pin sizes (1/2" and 5/8". The locks are both very similar, I wouldn't say one is more secure than the other.

  • Locking Pin Set Recommendation for Buyers Products Coupler w/ 3-Position Adjustable Channel

This kit comes with both the coupler and hitch locking pins which are keyed alike so you only need 1 key to unlock them.

  • A-Frame Coupler Lock for Wide Latch
    There is a solution for you, though the Master Lock Hitch Receiver and Coupler Latch Lock Set # 1481DAT will fit coupler latches that are 2".

    The etrailer Surge Brake Coupler Lock part # e98887 is perfect for your needs. It has a 2-1/2" useable span and is 1/4" in diameter. This is the size they use for these.

  • Can The Kuat Hitch Lock # HL2 Be Used For Towing Applications?
    You will want to use the Master Lock Hitch Receiver and Coupler Latch Lock Set # 1481DAT when towing with a 2" receiver. This pin is 5/8" diameter to match the receiver and ball mount. The Hitch Lock for Kuat Bike Racks # HL2 is only 1/2" in diameter and was specifically designed to be used with a Kuat bike rack only for securing the rack to a 2" receiver.

  • What Coupler Lock Set do you Recommend for My Coupler and Reciever
    With the Master Lock Hitch Receiver and Coupler Latch Lock Set part # 1481DAT not meeting your needs in function I recommend using the etrailer Trailer Hitch Receiver and Coupler Lockset part # e99039 instead. These utilize a screw together lock set that work very very well. I like the coupler lock much more that the one that comes with the Master Lock set because it is not as long. The etrailer lock will snug right up against the coupler latch and will help prevent theft.

It has a 5/8 inch diameter, 2-1/2 inch span to fit the 2-1/2 inch overall hitch width.

  • Which Hitch Pin Lock Set Works with Aluminum Ball Mount Kit # AM3410
    Thanks for your recent purchase!! What I recommend is the trailer hitch lock # AM3492. It is 4-1/4 inches long and will work with the aluminum ball mount kit # AM3410. The hitch lock # AM3492 will also include a hitch pin lock and both keys are keyed alike. The Master Lock hitch lock set # 1481DAT you referenced will not work with the aluminum ball mount kit # AM3410 because it's too short. It's only 2-3/4 inches in length. I included a couple video reviews too.
