Today, we're going to be taking a look at the Square Pipe Mount Swivel Jack with the included foot plate and drop leg. This utility jack is going to let you raise and lower your trailer. It's going to have a lift capacity of 7,000 pounds and a support capacity of 8,000 pounds. It's going to feature the tubular swivel design. This is going to let you swing the jack up along the trailer frame for storage and bring it back down when you're ready to use it. It does come with the pull pin. It's going to hold the jack in either position, so you just pull that out.

It's going to be connected to the jack with a chain lanyard. That way you don't have to worry about misplacing that or losing it. It's also going to come on with the weld-on pipe mount. This is a female pipe mount. It's going to have an outer diameter of 3 inches, inner diameter of 2-1/2 inches.

This gets welded on to the trailer frame and then you can see how it would allow the jack to swivel inside there. That way you can rotate it up or bring it down for use. Four holes are going to line up with the 4 holes going right here, so that way when you have it in a stowed position, you can have it facing forward or rearward, direction of the trailer, so totally customizable in that department. Whatever is going to give you the most clearance and not interfere with anything on your trailer, but that is included. That's a raw steel finish so it's ready to be welded onto your trailer. The square jack is going to provide more side-load capacity than round tube jacks. It's going to have the top-wind handle, has a nice claw grip design to it, so it allows for a comfortable easy grip when cranking.

It makes raising and lowering much easier. This can be flipped over to a stowed position if you want to do it that way, so that's a nice feature of the handle mechanism. The handle radius measured from the center of where it mounts to the outer edge of the grip area, that's going to give us a measurement of about 9-1/4 inches. The jack is going to be made from a steel construction. The outer tube is going to have a really nice black power coat finish on it. The inner tube, drop leg, and foot plate are all going to have a clear zinc finish, so overall, it's going to do a great job at resisting rust and corrosion and lasting a long time. I want to take a few moments just to show you the drop leg.

It does come with the included pin and clip. Now, keep in mind, drop legs are going to allow for increased lift. It's also going to save time when raising or lowering, so I just want to show what the drop leg is and how it works. This drop leg is going to be a 5-hole design. The amount of travel that this drop leg offers is going to be 13-1/2 inches. That measurement is taken from the center of this hole to the center of this hole, and then it can be adjusted in increments of 3-3/8 of an inch. The 3-3/8 inch measurement is the distance we have between each hole measuring center on center. Again, the drop legs are going to help allow for increased lift, and it's going to help save time when raising or lowering the jack or your trailer. It simply just goes directly into the inner tube there. You line up whatever hole you want for your application and then secure it in place by installing the included pin and securing it with the clip on the other side. Now, you can see that the foot plate is going to be welded to the drop leg. The foot plate is a nice large design. It's going to measure about 6 inches by 8 inches, so it's going to do a great job at spreading out the applied weight, especially on softer ground to prevent sinking, and it's going to help increase overall stability. I do want to point out that the inner tube is going to have a hole on each side. That way you can rotate the drop leg position, which is going to change the direction of the foot plate, so if you want the foot plate going this way, you just take the drop leg out, rotate it, and reinsert it. The jack allows for pretty easy maintenance. Right here, you're going to have a zerk fitting. That way you can attach a grease gun to it, pump your grease in and lubricate the internal components. A few measurements I want to go over with you real quick. We're going to take a look at the fully retracted measurement, so the jack is at its lowest setting. I'm going to take a measurement from the bottom of the foot plate to the center of that weld-on piece, and that measurement is going to be about 14-1/2 inches. When we did that measurement with the jack fully extended, that was about 29-7/8 of an inch, so this jack is going to offer a travel or lift of 15-3/8 of an inch. Then, again, the drop leg is going to add an additional 13-1/2 inches on top of that, and the 13-1/2 inch measurement can be adjusted in 3-3/8 inch increments. This is a square design. The outer tube is going to measure 2-1/2 by 2-1/2. The inner tube is going to give us a measurement of 2-1/4 by 2-1/4. That's going to do it for today's look at the Square Pipe Mount Swivel Jack with the included Foot Plate and Drop leg.

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. 481725
