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.

Switch easily between trailers with this adjustable, aluminum ball mount. Go from a 4" drop to a 5" rise. Tow up to 8,000 lbs with the 2" ball and up to 10,000 lbs with the 2-5/16" ball. Self-locking system helps prevent theft.

Debated between this hitch and a B&W. Went with the Fastway for ease of use and the ability to take the hitch on or off my vehicle within a few minutes. Solid build quality and provided quiet confidence while pulling my 4,300 lb. travel trailer.

- DTALBM6400-2S

I just got this today, and haven't had time to install it. But I bought it for the quality and the way it locks.

It worked like a charm. Hauled a car from Colorado to Arkansas. No issues

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.

- DTALBM6400-2S

Love the finish Easy on off install removal Easy adjustments for different trailer heights

Works great ! I get a lot of compliments on it and the theft prevention sold me on the sale.

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.

This Ball Mount is solid, well made and very secure. This is my second one in the past year. The first was a 6" for my 3/4 Ton truck. They are not inexpensive, but they are worth it. If your looking for the best adjustable, self- locking Ball Mount then this is it.

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

I have not had a chance to use the ball mount yet but it is easy to use and fits receiver with no issues. I recently purchased a Curt class V receiver that is installed below my OEM receiver. With the drop installed in the Curt receiver in the upright position, the back of the ball mount comes very close to the bumper on my 2011 Ram 2500 crew cab. I will see if there are any contact issues when actually towing and revise my review, if necessary.

After using the hitch for six months, with the Curt receiver, I found it does contact my bumper when positioned at that height, causing scrathes. I also find that I can not unlock the receiver pins without having to tap pretty hard on the pin ends.
-- comment by: Kevin M - 07/17/2014

Both products are working well. I initially had a problem with the ball mount, which you promptly followed up on, giving me the Diversi-Tech support number. After talking to the rep and following a couple of his suggestions, the mount is now working well.

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

Excellent hitch. I would make only one change in my purchase selection and that is to go with the chrome plated ball. I went with the stainless thinking it would not show discoloration (like darker coloration or rusty looking) but it does and I believe the Chrome plated would have looked better.

Stainless steel contains chromium, and when exposed to oxygen it forms a thin invisible layer called chromium oxide. Rust can form when this layer is damaged from exposure to high humidity, high salinity environments, or mechanical abrasion such as the steel coupler over the ball. A good way to remove the the rust would be to mix 1 tablespoon of baking soda in 2 cups of water, rub the baking soda solution on the rust stain using a toothbrush. Baking soda is non-abrasive and will gently lift the rust stain from the stainless steel and then rinse and wipe the spot with wet paper towel. We do have a chrome ball mount with part # DTALBM6600
Self-Locking, Adjustable 2-Ball Mount w Chrome Balls - 2" Hitch - 6" Drop, 7" Rise
. It does the same job as the stainless steel for a little less money. Over time with any chrome plated ball the chrome plating can wear off and then cause the metal undeath to rust. If you were to stick with a chrome plated hitch ball then greasing it with part # 58117
White Grease Hitch Ball Lube
before each use would help to prevent the coating from wearing off.

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

I bought this product for a Super C motorhome I tow a 14 ft trailer with a car in it or two motorcycles is fully adjustable and I love it I'm calling about 6007 thousand pounds it's a great product

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

This is the best (and nicest) hitch I have ever owned and got rid of all my others. It adjusts easily to my different trailer heights and is both secure in the height selection and the receiver. The only think I don't like are the small rubber dust covers over the locks...they tend to not stay in-place. I purchased the 2-inch mount but my new truck has a 2.5, for which I needed to get an insert to work. I would recommend this to anyone wanting a single hitch solution.

- DTALBM6825-2S

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

Superior quality product. Material cost alone worth more than selling price! The hitch & ball mount BOTH have internal locks Internal locking system works butter smooth and eliminates concerns of theft. Much less cumbersome & longer lasting than traditional pin/lock combos. Ball mount arrives with balls already mounted Order 2.5" mount to eliminate sleeve (if any) on existing hitch for no rattle fit. Appearance is very impressive & I am very pleased with this product.

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

Very strong, easy to install and very secure. Yes a bit pricey, but well worth the money. I did notice there was what I thought was an unusual amount of play in the receiver. I called etrailer and Marcia was so very helpful and very concerned that I may have received the wrong product. She even called the manufacturer and found out what the changes that were made by the manufacturer which made the pictures incorrect. My hat is off to Marcia and all the folks at etrailer

Good Morning Patrick I just love the hitch for several reasons. It works flawlessly to start with and I am able to adapt to almost any trailer I choose to pull. It is definitely a plus being able to move the hitch to adapt for proper levelling. I have a lot of people just stop and look at the hitch when I am in parking lots, and a time or two they have asked me where I got it. The only downside is the fact that while people see it, so does my back up alarm...

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

Beautiful machine work. Nice finish. Everything works as stated except the anti rattle pins built into the top. Due to construction of my 2012 Dodge 3500 hitch the pins don't hit in the right spot to stop rattle. I bought an anti rattle device and its real tight.

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

After a lot of research and comparisons I called etrailer to see what they could do for me on the hitch I wanted. Katie D. was very good at answering my questions and the order process was seamless. Received notification on the order as well as shipment details to track the item. What I like the most is the fact the lock is built in and the hitch looks great on the truck. Not only that it is solid and does not rattle. It showed up a couple days earlier than expected and will be ordering again with etrailer and Katie D. will be getting my business! Thanks.

Review from a similar Flash ALBM Series in Trailer Hitch Ball Mount

This is my 2nd hitch. The 1st one I purchased had Chrome Balls, do yourself a favor and do not buy a Chrome Ball Hitch, I do not think the Stainless Balls were an option when I purchased 3 years ago. The issue with the Chrome ball is they RUST! It ruined my hitch and unfortunately the balls can't be replaced which is pretty stupid. Looking forward to the New Hitch and Stainless Balls holding up better than the 1st Hitch, i'll keep you posted.
