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.

Items delivered ahead of schedule, I’m very happy with my purchase and the service. The aluminum drop hitch quality is outstanding, looks great and is super lite!

by:

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.

Works as expected the coupler lock snugs up tighter than my previous lock.

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.

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.

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


Comments
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.

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.

Piece of mind when parked outside. Easy to use.

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.


Comments
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.

Great product. Stainless steel, and it reduces the number of keys we need to carry around. I like the dustcover over the lock, it fits well. Both locks fit tight against my hitch/ball lock, which makes it harder for someone to get in there with anything to cut them.

This product gives me a better sense of security when pulling my new trailer. Finding a trusted name like Master Lock with both the trailer coupler and the receiver lock both keyed alike was also a big plus.

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

Totally painless dealing and FAST! I would have had to drive miles out of my way, but instead it comes right to the door. I really like the double lock package with a trailer hitch lock and the tow receiver lock that are keyed alike. Thanks and I'll be back for more.

  • Keyed Alike Hitch Locks for 2-1/2 Inch Receiver and Trailer Coupler Latch
    Although it isn't sold as a kit, we do offer a hitch lock that's compatible with a 2-1/2 inch receiver and a coupler latch lock that can be keyed alike. For the hitch lock, use # e98881 and # e98886 for the coupler latch lock. On the product page for both items, right above the 'add to cart' button there's a drop-down menu where you can choose the option of a keyed uniquely or keyed alike lock. If you choose the keyed alike option on both locks, they will be keyed alike for the same...

  • 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". Instead, I recommend the Bulldog Easy Access Coupler Lock # BD580409 which has a 1/4" pin diameter and spans 3-5/8". I've added links to video reviews of this coupler lock for you to take a look at.

  • 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...

  • 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...

  • Availability of Keyed Alike Trailer Coupler Latch Locks
    We have what you're looking for but Master Lock doesn't offer a keyed alike coupler lock. I'd recommend using a similar coupler lock, like our part # e98886. Choose the 'Keyed Alike' option from the drop down menu, and choose the quantity of locks you need.

  • 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.

  • Availability of Keyed Alike Sets of Master Lock Receiver and Coupler Latch Lock Set Part # 1481DAT
    The Master Lock Hitch Receiver and Coupler Latch Lock Set, part # 1481DAT is not available keyed alike. Both locks in the set are keyed the same, but we are unable to obtains multiple sets that are keyed alike. If you are interested in multiple units of hitch and coupler lock combo that are available keyed alike, take a look at part # e99039. I apologize for any confusion.

    To lock the shank to your trailer hitch receiver and the hitch ball to your trailer coupler on your Husky Center Line Weight Distribution w/ Sway Control # HT32218, I recommend using the Master Lock Lock Set # 1481DAT. This locking set uses the same key for both the trailer hitch receiver lock and the coupler latch lock.

  • 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.

  • 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.

I understand it is 1/32" smaller that your request but it is designed for your purpose. I've included a video I did on the lock for you to check out and see some more specifics on it.

It has a 5/8 inch diameter, 2-1/2 inch span to fit the 2-1/2 inch overall hitch width. The # e98881 lock is for 2-1/2 inch hitches (inside width of receiver) and the recommended lock, # 1481DAT is for 2 inch (inside receiver width) hitches.
