Video Transcript for Master Lock Hitch Locks - Standard Pin Lock - 1481DAT Review

Speaker 1: Today we're gonna take a look at the Master Lock hitch receiver and coupler latch lock set for two inch hitches. The trailer hitch receiver lock, this is used in place of your standard pinning clip and it's to prevent theft of your ball mount or any accessories such as cargo carriers or bike racks. This one's a patented stainless steel swivel head, which will rotate 360 degrees for easy access.You pop open the cap, you can see it has a nice brass keyway with an aluminum casing, which will conveniently face towards you, not off to the side. It has a key retaining design, which will prevent false locks. Basically, when you put the key in here, the key can't be removed unless the lock is secure in place. It is a push to lock mechanism, which makes locking easy and foolproof.

Basically the lock clicks into place so you can feel and hear that it is locked. Right now, if you just turn this a quarter of a turn, you can unlock it. Then when you leave the key in it, you just push it on there and it locks right into place. You can hear it click. Remove your key and then it's not going anywhere.The coupler latch lock, this part right here, this will keep others from releasing your trailer once it's hooked up.

This adjustable lock has six locking positions, anywhere from 9/16 of an inch to 2 3/4 of an inch, so it is designed to fit the 5.8 inch latch width, which is most standard couplers. It'll fit a one inch latch width, which is most 2 5/16 ball couplers, and it'll even go up to a two inch latch width, which is most wide latch ball couplers.Same way on this, you pop the cap off, put the key in here, turn it. You can see it slides right off. Slide this through your latch, slide this on, turn your key, and it's locked right into position, just like that. If you leave the key in it, let me just show you here, if we put the key in it and leave it like that, you can actually see that you can pick whichever position you need it at.

Once you get it in that position, then just turn it and that'll lock in and keep it in that position.Both locks are made of a corrosion resistant stainless steel. They have the integrated keyhole covers, you can see here, to keep out dirt and moisture. The keys, they come with two keyed alike keys, so the same key works on both these locks. A few specs on this, the application, this is for a two inch by two inch trailer hitch receiver. The diameter on this lock pin is 5/8 of an inch.

The inside pin length, or the inside span, usable length, if we put a ruler on that, is right at 2 3/4 inches. On the coupler, that latch lock pin diameter is 1/4 of an inch.What I'm going to do is show you how the hitch receiver lock would work. Happen to have a two inch hitch receiver here with a ball mount in it, just with a pin and clip. If you pop off the pin and clip, then you can see you can pop open your cover, put your key . Let's get the . There you go. Then just turn it, pops right off, then you can slide your pin through your hitch and your ball mount. Then just push it in and it locks right into place. You can see it has the 360 degree, so you can get the keyway to where you can see it. Pop the key off, put your cap on there, and it's all locked, ready to go. Again, to remove it, again, just put your key right in there, turn it and it'll pop right off just like that.That should do it for the review on the Master Lock hitch receiver and coupler latch lock set for two inch hitches.

Excellent packaging, delivery and overall satisfaction with the product and the service. Looks nice on my Hummer H2. 156946

The hitch lock is a little short. Really have to compress the rubber to get it to engage. 261036

Your email could not be more timely. Unfortunately the master lock system that I purchased was not secure enough to prevent theft of my very expensive equalizer weight distribution hitch from my truck 2 weeks ago. parked right next to my camper that I was occupyingI am very disappointed as this master lock did not even seem to slow down the theft.

Easy to use, matching keys, and easy access to the keyhole. 146508

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.

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. 439955

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.

Easily and securely locks my hitch and trailer latch for peace of mind. The Hitch lock is perfect size, the Trailer Latch Lock is much longer than I need, as I lock on the first notch and there is still probably 5 inches sticking past the lock. Overall the product does the job well. 54556
