Video Transcript for Fastway Self-Locking, Adjustable 2-Ball Mount Review

Speaker 1: Today we're going to be taking a look at the fastway self locking line of adjustable two ball mounts.So, if you're looking for an easy to use, versatile ball mount, our fastway self locking ball mount, is going to be able to adapt to several different trailers, keep everything secure without any extra components, and look good while doing it.If you tow multiple different trailers, chances are they're going to have a different coupler size, or they're going to have a different tongue height. So, we're going to have to switch out our ball mount. That can become a hassle, especially if we tow so many different trailers in any given day.Well, our fastway ball mount's going to take care of that, because we're going to be able to switch our height, because it's going to be adjustable. But it's also going to give us two different ball sizes.Our ball mounts are going to come in a lot of different configurations, we're going to have some that are going to be available for the two inch receiver tube like we have here. But some also available for the two and a half inch receiver tube. And they're going to have varying different drops and rises that way you can pick one that's going to work with all of your trailers.Now, one thing that you're really going to appreciate about this, is that it's going to have self contained locks.

We're going to have this rubber grommet here, that's going to have a plug over our lock cylinder, so it means we can just lift it open. And you'll notice that we're going to have a tubular key, so we're not going to have to worry about it being picked. But if we unlock our ball, we can slide it up or down to get the appropriate riser drop. And then if we remove it, you'll notice that we're going to have another lock core right on the base here.Now, this is going to be used so we can lock our ball mount directly to the receiver tube. And if you watch, you can notice that the pins are going to go in.

So, we're not going to have to worry about losing our lock, because it's going to be self contained inside the ball mount.We can simply just slide our ball mount in place, line up the pin holes, and then rotate our key, until those pins extend out. And you can see that's not going anywhere. So, we'll make sure that pin is in all the way. And slide our ball mount on, then we can rotate the key, until we get it into the slot, and it will lock it in place.Now, our ball mount's not going to go anywhere, and we're not going to have to worry about anybody stealing it from our receiver, or taking the ball platform. And for extra piece of mind, to make sure that you have the ball mount in the correct spot, it isn't just hung up.

The key itself is not going to come out until it's fully in the locked position. So, even if I get it half way and the key is turned, it's still not going to come out, because that pin hasn't fully inserted. But once it does, the key will come out.Each one of these notches in our ball mount here is going to be in one inch increments. So, right now, we have them in rise position. And if we need to go up say two inches, we can just go up two notches, and that will give us a two inch rise.

And the same thing if we we're going down in the drop position.Each one of our ball mounts is going to come with a total of four keys, and both sets of keys are going to work with both the locks. With the locks being right on front of the shank here, and on the side of the ball platform, it's going to make it a lot easier than trying to get underneath the hitch here, messing with the pin and clip, or locking device, and it's one less thing that we have to worry about misplacing. Because our locks are going to be internal, and they're going to be sealed off from any kind of dirt or debris, so we don't have to worry about them getting damaged.Each one of our ball mounts is going to be made out of a solid piece of aircraft grade aluminum, so we're not going to have to worry about any weak points, because there's no welds in them to break. So, they're going to be nice and strong, and durable, but yet lighter weight than steel versions.Our ball mount right now we have in the drop position, but you can flip it over and put it in the rise position. In case you have a trailer that's taller than the other, so we can get a little bit more height, or drop for whatever we need.Now, each one of them's going to have two different balls on it, we're going to have a two inch ball, and a two and five sixteenths inch ball. And switching them's going to be just as easy as adjusting the height, we simply unlock it, flip the ball platform over, to whichever ball we need.And when it comes to the trailer balls themselves, we're going to have two different options. We'll have the version we have here, which is gonna be a steel, chrome plated ball, which is your typical trailer ball. And then we're going to have the stainless steel version. Now, these are going to be made out of a 303 stainless steel, and they're going to be extremely rust and corrosion resistant. It's going to be really good for marine applications, or anywhere that has a lot of moisture, even humidity, so we're not going to have to worry about rust.And that is another big benefit of the aluminum ball mount, it is going to be rust and corrosion resistant, so we know it's going to have this nice, polished mirror finish for a long time.Now, since our ball mounts are going to come in a variety of different configurations, the shank size, and the ball size, is going to make a difference on how much it can handle. So, whenever you're towing, you always want to double check your hitch, as well as the vehicle's owner manual, and go with the lowest rating.Being able to adjust the ball mount up and down, is nice, but if we don't know how much of a drop or rise we need, it doesn't do us much good. So, we'll show you how to measure for the appropriate riser drop for your trailer. You're going to want to measure from the ground to the inside top edge of the receiver tube opening, you're gonna make sure that your tow vehicle is nice and flat and on level ground whenever you make your measurement.So, right here, we're getting right about 17 inches. Now, we can come to our trailer and again, you want to make sure that your trailer is nice and level. So, we have our trailer chalked. And we'll come up to the coupler, and we'll measure from the ground to the bottom edge of the coupler here. Which I'm getting right about 21 inches. So, there is about a four inch difference. But since my trailer is higher, I'm going to want a four inch rise.So, we'll take our ball mount, we'll make sure that the pins are all the way in, and since I need a rise, I'll put it in the rise position. Slide it in the receiver tube, line up the holes and turn the key and lock it in place. And we can grab our ball platform, and again, open up the plug, take our key, make sure that pin goes all the way in. Pick the appropriate ball for your trailer, we'll slide it down close to where we need it. And once we have it lined up, we can turn the key and replace the plug.So, now we can go and double check our measurements, make sure we're pretty close to that 21 inches, and we are. Now, all we have left to do, is back up and hook up to our trailer. That'll finish up your look at the fastway self locking line of adjustable two ball mounts.

I love this product. I have 2 different tow vehicles, and having the option to change the height of the ball is a big advantage. I also like the feature of having 2 different size balls on the same mount. This product has much flexibility and suites my needs perfectly. Plus it looks sharp. 369888

Fantastic product! Made with high quality materials and buffed to an amazing shine! Not only looks great but its extremely durable. I had one previously that I sold with another vehicle with the chrome balls that worked great for the 5 years I had it pulling 9,000# plus boats/trailers. Looking forward to even greater durability with the stainless steel balls on this hitch. 177255

Review from a similar Self-Locking in Trailer Hitch Ball Mount


Like most of the reviews on this product, a little skeptical on the locking pin in the receiver. Seems like it should extend out a little further when it’s locked in the receiver.... It is well built and looks great. It’s what I wanted and can’t wait to put it to the test! 573983

Have not used product yet, however customer service was excellent. I had received the wrong ball mount and contacted customer service. Dana was understanding and immediately sent out a return label and the correct ball mount. Couldn't ask for any better.

I was very confused in trying to determine the type of hitch to use for my just purchased 2019 Ford Superduty truck. The good folks at E-trailer worked with me and I selected a hitch with just the right drop. Years ago I purchased several tires from these folks and they are wonderful to work with. Very professional and (most important) PATIENT!! 706320

After about 7 months, the lock that locks and releases the pin to the receiver was completely frozen stuck, and the key to the lock twisted off (pretty flimsy). After re-lubing the pin and lock again, twisted the other key off. i had to mangle the lock to get it off of my truck, and unit is now completely worthless... 404043

Review from a similar Self-Locking in Trailer Hitch Ball Mount


Serves the purpose needed. Love the fact that it has a 2,000 lb tongue weight and a 14,000 lb tow weight. it gives me that extra safety margin. One big drawback is that I ordered two keyed alike replacement locks because I have another hitch different size but I am not able to remove the set screw following the instructions no matter how hard or what ever I use. So I am presently stuck with using two different keys and with a set of keyed alike locks. 591470


Comments
When its installed, Fastway uses a small amount of thread locker on the set screw, so its designed not to be easy to remove. Try spraying a spray lubricant like PB Blaster or WD-40 in the set screw hole. You might need to repeat this several times for the lubricant to penetrate. If several attempts of this doesnt work, you can use a # 1 extractor to remove the set screw. If that doesnt do the trick, I was told you could send the ball mount to Fastway, and theyd re-key them for a fee.

Still not able to remove the set screw to have two locking ball mounts with one key. i am able to remove the screws in my other two mounts but not this one. This one was put in two tight andor too much loctite.

You may try using some penetrating oil on the set screw to loosen it up a bit. Over time they can become harder to remove. We have a video to show how to swap out the lock cores.

Great solid hitch but the lock is poor quality. I left it on the truck for several months (with lock protection cap on) and one day I went to remove. Found lock tumbler had shifted and was unable to insert key to remove. Had to drill out lock to get ball mount off the truck. I know have a $80 aluminum paper weight. 591181

The key driven locks look questionable at first, but they hold just as solid as the pins. I don't think I have pressed it's limits with my power dump trailer, but it definitely meets my needs. I generally hook it up to the top 2" receiver on my torklift 20k receiver. Works great. Feels substantial! 550239

Review from a similar Self-Locking in Trailer Hitch Ball Mount


I previously purchased this product for a 2" receiver and was very pleased with it as I formerly kept five hitches in my truck for five trailers - each was a different height and one was a 2 5/16 ball with the others being 2". Consequently, I went from hauling around about 75 pounds of hitches to one at about 15 pounds - plus, being aluminum, it had greater load capacity and looked a lot nicer than the steel hitches. My new truck has a 2 1/2" (class V) receiver and the former hitch cam operated lock pins did not come out far enough to engage the receiver when an adapter was used; hence, the need to buy another one rated for 2 1/2" receivers. The new one arrived and it was a 2" hitch with extended pin lengths and an adapter to make it fit a 2 1/2" receiver. Unfortunately, the adapter was off center and I was unable to insert the unit into the receiver on the truck. There are two screws that affix the adapter to the hitch insert and after about an hour I was able to get the new hitch/adapter to fit my receiver using one of the two screws to get the sleeve and hitch lined up properly and discarding the second screw which would have caused further misalignment. While not very happy about the latter, I am pleased with the result. I would strongly suggest that the manufacturer have some type of quality control as it was very apparent to the naked eye that the sleeve and hitch were not properly aligned. As far as Etrailer, they have always been great to deal with and offer all kinds of support. I have been purchasing equipment from them for many years. 340339


Comments
After a year the hitch has worked well. Recently I was in VA with freeing rain then below freezing temperatures. I had to reverse the balls due to what I had to tow. To my surprise the locks had not frozen and worked as designed. Regarding salt exposure, I reside in Florida and after my trip to VA my vehicle was covered with salt. I used Salt Away for boats coupled with a nozzle. The unit is similar to a hose mounted liquid fertilizer applicator and allowed me to thoroughly clean the nooks and crannies including the hitch. It will not damage paint and is supposedly environmentally friendly.
