Video Transcript for Review of etrailer Trailer Jack - Side Frame Mount Jack - TJDP-7000-B

Jeff: Hello everybody. This is Jeff at etrailer.com. Today, we're going to take a look at the square weld-on topwind pipe Mount swivel jack with the footplate and a 7,000 pound lift capacity. Now this utility jack lets you raise or lower your trailer. It is ideal for agricultural and commercial applications. It is a square jack so it provides more side load capacity than your standard round tube jacks.

The outer tube is a black painted outer tube has a width of about 2 1/2 inches. The inner tube is a zinc finish on it has a 2 1/4 inch width. I do want to zoom in just to show you a couple parts up here. It is a weld on installation. Has this included female pipe Mount.

It is a tubular swivel design. So it lets you twist the jack up for storage and then down for use.Basically all you do is pull this pin out and then this pipe, this female pipe Mount is what will be mounted on your trailer frame. So with your jack in there, all you have to do is twist it up parallel to the frame, drop your pin back in there. And it all secure it in the storage position. And then when you want to use it, just pull your pin back out, swing it down like it is now, drop your pin in and you're ready to use it.If you notice the pull pin itself is attached to this lanyard, so you won't get lost.

You always have the pull pin available and again, you just drop it in and push it all the way down and it'll hold it into place. The handle right up here at the top is a top line handle has a nice black claw grip on it for comfortable, easy cranking. If you crank it clockwise it'll raise it. If you go counter-clockwise it lowers it. And the handle will easily fold away for storage, you just flip it over just like that.

Handle radius on this is going to be about 9 1/4 inches. On this side here if you look here, you can see there's a built-in grease circ fitting and you can attach a grease gun to that and it'll lubricate the internal components of the jack.Zoom back out. The drop leg right down here, this will allow for increased lift, saves time when raising or loading. You can just again, pull the snapper pin out and drop the drop leg down to make up a lot of the lift you'll need and then put the pin back in. The foot plate is welded on so it minimizes sinking in the ground and is zinc plated for corrosion resistance.A few specs on this jack, the lift capacity we mentioned is 7,000 pounds. The support capacity is 8,000 pounds. The foot plate on the very bottom here, the dimension on that, it's going to be right about 7 7/8 inches by about 5 7/8 inches wide. The pipe mount diameter, outside this is the female pipe mount that welds onto your trailer frame. Overall outside is 3 inches inside is 2 1/2 inches. And last measurements I want to give you as a jack height, which will be measured from the bottom of the foot, to the center of the pipe mount. When it's fully retracted, that's the position it is in now, it'll be right about 14 1/2 inches. If we crank this all the way out extended position is going to measure from the ground to the center. It's 29 7/8 inches. So it's going to give you the jack will lift about 15 and 3/8 inches.If you want to add this 13 1/2 inch drop leg travel, it'll give you a total lift of 28 and 7/8 inches. But then again, just to show you flip the top line handle, crank it and that'll raise your jack. And go counter-clockwise and it lowers it. Once you hit up all the way lower it'll stop. You just flip the handle over. But that should do it for the review on this square weld on top line pipe mount swivel jack with the foot plate and a 7,000 pound lift capacity.

Was having issues with the trailer lifting the backend of my truck when I loaded tractors. When I would drive the tractor on the back of the trailer would go down from the weight on the rear which caused the front of the trailer to lift the backend of my truck. So, I bought a couple of the Square, Pipe Mount, Swivel Jacks with Footplates and a Drop Leg. They are Topwind, 7K, Jacks. I had them welded on. This should stop the issue I'm having. I know the 7K was a little over kill but the price was great.

The Jacks are working great. Definitely fixed my problem and make easy for me to load heavy equipment now. Thanks again for a great product!!!

Top wind 8000 lb swivel trailer jack. Was easy to install it works very smooth. I would recommend this jack.

- TJDP-7000-B

Just what I wanted to make my trailer safer when loading. Thanks

- TJDP-7000-B

I am happy with the jacks. Good, solid and well made. Just as advertised. I mounted these on an equipment trailer. 32" from the rear, on both sides was the best location on my trailer. The trailer needed the extra support during loading and unloading, to stop it from rearing up in the front. They worked very well and solved my problem. I would recommend them to others.

- TJDP-7000-B

Came as described. Only thing I’m I didn’t like is the slip it has. I think it needs a tensioning screw in the back like I have on a weight distribution hitch i own. Didn’t receive one with this product.

- TJDP-7000-B

Very good quality, heavy duty. This replaced a much lighter duty jack on a batwing mower that was OEM and failed (bent).

great, still going STRONG!
