Video Transcript for Pro Series Detachable Caster with Pin Review

Today, we're going to be taking a look at the Pro Series 6" Detachable Castor with Pin for 2" Diameter Jacks. Offering a 1,200 pound capacity, the part number is PS1400750340. This castor wheel is designed to allow you to easily maneuver your trailer around. As you can see, as we go side to side, the castor rotates. That way, we can maneuver it around. Generally, these are going to work out best on a flat surface, concrete, asphalt, things like that.

This wheel in gravel, sand, mud, dirt, it's going to want to sink in slightly or not roll as smoothly, so definitely keep that in mind. But overall, it can help maneuvering, especially moving it around by hand. The one thing you want the keep in mind, I don't like moving a trailer around on this wheel with the jack all the way up. If we extend this jack out too far, it puts a lot of pressure on the connection point up here as we're maneuvering it. So just keep that in mind.

But all in all, it's going to do a really good job at helping you move your trailer around from here to there.Overall, the construction is nice and heavy duty. It has a good feel to it. I don't think we're going to have to worry about flex side-to-side or anything like that. All the steel, you can see, has that white zinc coating on it, so corrosion should be kept to a minimum. Our pin here is easy to attach and detach.

Generally, I don't like to keep one of these on as I'm going down the road, just in case the pin we're to fail or something like that. We're going to have the six inch tall wheel, so that can help with little obstacles we might encounter to help roll over it instead of it get stuck. That wheel is also going to be two inches wide. So while it's not exactly designed for softer surfaces, that will help to dissipate that energy out a little bit so it doesn't sink in as badly.To get your caster installed, you'll either want your trailer hooked up to your vehicle, or you can place a couple of jack stands underneath the tongue. Then we need to lift our jack up to give us the room we need to get it slid on.

Once that's up high enough, we'll slide the wheel on, place our pin through, and then just clip it on. At that point, of course, you can see it's also going to act as a slight lift for your trailer, so you won't have to move your jack quite so far up and down. Now we're ready to remove our jack stands and it's going to be ready for use. That's going to complete our look at the Pro Series 6" Detachable Caster with Pin for 2" Diameter Jacks.

Wheel will not rotate under load when trying to push trailer tongue around.

You mentioned that it is not rotating while under load. I wanted to ask you a few questions. What type of surface are you using the wheel on. Generally, these are going to work out best on a flat surface, concrete, asphalt, things like that. When used in gravel, sand, mud, dirt, it is going to want to sink in slightly or not roll as smoothly, so definitely keep that in mind. What is the weight capacity of the trailer? How far are you extending the jack? It is extended too far it will put a lot of pressure on the connection point up here when maneuvering it. Just keep that in mind.

As advertised! It’s a pretty loose fit for the jack but it works.


The Pro Series 6" removal caster wheel fit the 2" shaft on my trailer jack like it was supposed to fit. Excellent product.


attached directly to the bottom of the trailer jack as described. appears to be good quality.


Works like a charm. It sure beats trying to lift and more a trailer around without it. Worth the purchase.

Still works great! Moving my flatbed 12 trailer around is fast and easy.

Here are some pictures of what I used your product for. The splitter just had a fixed position stand and it is fairly heavy so it was difficult to hook to the ranger because the stand had to be removed first. Now I can just let it down to the hitch and with the wheel I can also move it around the shop without lifting it. We also put an extra mount on the back so the wood falling from the splitter would not damage it. Thanks for the good service,


Great wheel with a nice clip. Fits the ultimate trailer jack perfectly.

still working great

This 6" caster wheel enables me to move my 16 foot car hauler trailer on level asphalt or concrete manually. This makes hook up to my class A Motorhome much easier. I can now store the trailer in my driveway by hand. Courtney B. was very helpful during my order of several items.

This wheel makes moving my trailer by myself easy. Easy to install and remove.

This item does the job I intended. My enclosed motorcycle trailer came with a sand pad only. This sand pad is the right thing for most of what I need it for. However, the trailer jack wheel in this review did its job one time. This is not to say it failed after one time. I am saying I've only used it ONCE and it performed well.
It is considerably taller than the sand pad, so with the sand pad attached to the jack I had to jack up the front of the trailer with its jack as far as it would go, drive under the top of the drop hitch with the tongue of the trailer and slowly lower the trailer down on TOP of the 4" drop hitch (wheels chocked on the trailer, of course). Then, after raising the jack all the way back up, I very carefully removed the sand pad and replaced it with the caster. Once that was done, I screwed the jack back down until it rested on the caster. I was then able to position the trailer into it's tight parking spot front-end first at the hotel. FINALLY! We were all set for a week of riding the beautiful mountains of Colorado!

Great! Only had to use it once though.

Drop in replacement for the one I broke. Simple and well built for my needs.


Just what I needed!


This wheel was of good quality and works well on my Ranger boat trailer.


Great as always

Richard - 08/21/2022


Just what I needed. I have a cargo trailer and the jack on the front had a flat plate. I replaced the plate with this wheel and now I can move the trailer by hand on hard surfaces which is very convenient.


Excellent quality. Shipped immediately for a great price!


This helps to complete my wife's latest toy.. We have had many different campers and motor homes during the years. This is a great down size. The caster helps greatly whem parking the trailer .



Happy with the price and performance. I have not had the guts to fully test it out with 1200 Lbs. However with a loaded trailer it rolls fine.


Working great, good service from etrail er


Super easy to install and super easy to move the trailer around on garage floor. Enables me to tuck the trailer right up against the wall.


Easy to install and good quality product. The length of the tire is big enough to roll it over a grass. It make it easy for my 5x8ft Big Tex trailer.

The video that describe the product before I place an order was VERY informative.

It still works as expected and very happy with it.

This is a Great jack wheel to keep the trailer "UP" when the jack is holding the tongue up off the ground. No need for blocks etc. maybe put something flat under the wheel like an old frying pan, piece of steel etc. so it doesn't sink into mud. It also helps if you want to roll the trailer around on most surfaces as you don't have to lift the tongue of the trailer.

Bruce - 12/22/2020


heavy duty, perfect fit


Yep, its a wheel for the tongue jack. Fit and works just fine. I don't think I'd want to try rolling it around with 1200lbs on it, but its plenty solid enough for me, especially for the price. Good value!

After one year still fine. It does its job and its held up. My trailer gets rolled around a lot on dirt and concrete and its been fine. Very good value.
Aaron C - 08/25/2021


Packaged well, delivered on time, all purchased was delivered as expected. Great communications. Will continue to order through etrailer.


I choose to purchase an inexpensive caster since it's for a utility trailer that I only use 2 or 3 times a year. I was pleasantly surprised at the quality of the item. It was much better than the caster I had to replace. This is my third purchase from etrailer, the first two being trailer hitches. I've always been satisfied with the qualiity of the items and the first class service from etrailer.
