When you're juggling heavy-duty utility tasks, maximum adjustability is crucial. That's where the drop leg with spring return on the Pro Series Square Jack shines. It enhances overall extension, allowing you to adjust the 26" lift to your specific needs with ease and efficiency. This way, whether you're dealing with an agricultural, construction, or livestock application, you'll have just the right amount of flexibility and support.
Built tough to withstand harsh conditions, this jack features a robust steel construction. The inner and outer tubes come with a weather-resistant gray paint finish, which not only gives a sleek look but also protects against the elements. No more worrying about rust or damage over time—it's designed to last, giving you peace of mind during your heavy-duty tasks.
Whether you're setting it up on a car hauler, gooseneck, or utility trailer, the direct-weld design of the Pro Series Square Jack makes installation straightforward and reliable. It's perfect for users who need a solution that can be securely attached and is ready to handle a variety of trailer types, including fifth-wheel and enclosed trailers.
Don't let heavy loads slow you down. With an impressive lift capacity of 10,000 lbs and a static capacity of 12,000 lbs, this jack is equipped to handle your most demanding tasks. From lifting tons of equipment to providing stability, it's a powerhouse that's got your back when dealing with large weights.
The sidewind mechanism offers smooth operation, so you can lift and lower loads with minimal effort. Although the crank is sold separately, it's designed to work seamlessly with the jack, ensuring reliable operation every time you use it.
Integreating stability into its design, the onboard footplate ensures secure footing even on uneven terrains. Whether you're setting up on gravel, dirt, or pavement, the jack stays firmly in place, providing the balance and support necessary for all your heavy lifting needs.

I am very happy with my product. It was exactly what I ordered. I am happy with my serive.
We installed these jacks on the front of our shipping container trailer. They work excellent. Wish we had bought two more at the same time for the back of the trailer. Thanks MFCC
service was quick thank you
When I ordered the jack I thought that a handle would have come with it. I don’t know if I overlooked that the handle wasn’t included or it wasn’t represented well in the ad. I called to find out why the jack was missing the handle and was told all I ordered was the jack itself. I asked about ordering the handle while on the phone with the rep and was told there was over a 6 month back order for them.
Jacks arrived in one piece...luckily. Scratched and dinged up but they'll be functional.
As per usual, etrailer's shipping and packaging is an absolute joke. Literally laughable. Arrived later than advertised. Boxes were torn on both ends. 4x4 steel jack in a 16x16 box with one piece of "packing paper". Surely they have to know how inadequate this is and they just gamble on UPS/Fedex delivering their products on a velvet pillow.
I'll just be thankful that they only have scratches and scrapes rather than bent footplates and sidewinder arms.
The product appears to be well constructed. I installed on small stock trailer we use to haul horses and seems to be working fine. The base plate was slightly bent during shipment but should not effect performance.
works fine, should have bought one for each side of trailer front.

no problem. good product
This has the spring jack that works great. It cranks with one hand on a fully loaded trailer. Was a bit narrower than the original jack I took off my 30 yr old 4 star livestock trailer but I made it work.
Highly recommend for the price. At first it did seem a bit chincy but looks as it will hold up well
This is the first time I have ordered from e trailor and even though I have to return my order, e trailor is definitely going to be my go to place for parts. The price I thought was good for what I needed but what show up it was a hell of a price . They called me to check on my order , it arrived in three days free shipping . It was twice the jack I needed , but it was exactly what I ordered i could not use it. So they sent me a return label and gave me my refund awesome job guys.

`I'm resurrecting an old goose-neck trailer and the landing leg on it was rusted so bad I had to cut it off. So this one is a replacement. I always like the service I get from E-Trailer and the great inventory and prices. Thanks again
This is the best jack I have ever bought. My wife has left the jack extended after lifting the foot up and caught it on a hidden stump hard enough to stop the truck instantly and I was prepared for the worst when I went to look at it but there was no damage and it continues to be a great product. I will definitely buy from them again.
Shipping could have been more prompt. I placed the order on Wed.,the item was not shipped until the following Monday.Other than that the jack seems to be satisfactory.
Shipping was faaaaast! Product as described. Works well.
Fast shipping great product. Delivered on time.
Thanks
Fast shipping, received parts sooner than I thought!
it is the direct replacement for my pj trailer. everything went as planed. good stuff.
Cheaply built.
received in a oversize box with no packing looked like it had been in at least two crashes on its way here maybe a tornado, no stickers looked like a cheaper replacement very loose construction

Customer Service will reach out to you.
It does the job but its starting to show rust after a year of being installed.
This jack has a nice finish, I haven't installed it yet but it should work jjust fine.
Still works great after a year of hard use
great jack has worked out verry well
It was time to replace several jacks and these were thirty dollars cheaper than i can buy locally.

At that time, a year ago, the jacks and the handles were hard to come by. Today the handle part # PS1400920383, is available.
