When your trailer needs a stable lift, the Bulldog Square Jack delivers with an impressive 7,200 lbs lift capacity. Built for strength and stability, it's your perfect companion for supporting heavier trailers, whether you're hauling a car hauler, enclosed trailer, fifth-wheel, or utility trailer.
Need a jack that fits tight spaces? The compact square design of the Bulldog Square Jack makes it ideal for those snug spots where larger jacks simply can't go. Its welded construction ensures no burn-through on your trailer, and it offers superior side-load capacity compared to round jacks, maintaining strength when it really counts.
Designed for the harshest conditions, this jack boasts durable, heavy-gauge steel construction that's built to last. With a weather-resistant coating on the outer tube and a zinc-coated inner tube, this Bulldog jack stands resilient against the elements, ensuring long-term reliable service.
Cranking up your trailer doesn't have to be a struggle. Thanks to the smooth, ergonomic topwind handle, adjusting your trailer height is smoother and more effortless. This topwind design reduces the chance of bevel gear issues, offering a straightforward solution for reliable use.
The Bulldog jack's drop leg feature increases your range of extension, offering a total lift of 28-1/2 inches. This means you're primed for maximum adjustability on uneven ground, making it a breeze to stabilize your trailer no matter where your travels take you.
A stable setup is non-negotiable, and this jack's heavy-duty footplate with reinforcement ribs ensures just that. It provides sturdy ground contact, minimizing water retention, and keeping your trailer secure during loading, unloading, or when parked—perfect for sandy or uneven terrain commonly found on various job sites or campsites.

Jacks are strong and it is exactly what I need for my equipment
Needed an emergency fix for a trailer. Etrailer came through with flying colors the product worked perfectly.
I replaced a damaged jack with this one. It fit perfectly and is heavy duty. Works very well.
Have made multiple orders, fast turnaround. Free shipping. Will continue to make purchases.
Received exactly what i ordered. I chose free standard shipping and they upgraded me to 2 day shipping at no additional cost. I recieved my order in only 18 hours of ordering! THANK YOU etrailer! We can now get back to work with our new parts!
I didn't measure the old one bulldog product but was more large the leg when retracted, the new one is little short so just was positioning on the best way and fully disengage and welded and tested and just work fine. Thank you.
IT WORKS GREAT
I wanted something that would be strong and hold up over time. This Jack is used to support my stainless steel 6 hole dog trailer with my side X side loaded on the back. So it’s not light. I tend to do things by overkill but with this bulldog Jack it perfect for the job! Did some fabrication on making the mounting plates and fitting it in just right. A little taping it off and painting to match the trailer. I would highly recommend using this Jack and using Etrailer for all your needs!
It seems odd that it came with no instructions and there are no installation instructions on either the etrailer site or on the BullDog (Cequent) site. I have not had it welded on yet, but figured it will be less risky to weld it with it disassembled so that is what I have done.
I got the top wind unit this time because my last one was a Fulton with a side wind and the bevel gear broke and is no longer available, necessitating its replacement. I figure a top wind has one less thing to go wrong.
Works great unloaded. With any load it bogs down. A side wind might work better, as the longer radius of the top wind seemingly requires more effort.

Thank you for your review. One of our experts have tested the Bulldog jack requires 5 cranks to move the jack 1 without a load. Please keep in mind this jack is also rated for 7200 lbs lift capacity so be sure to not exceed that weight rating. It may also be easier to use a side wind jack like you mentioned because you are moving the crank up and down instead of side to side.
we use these on all our 14K trailers that come with smaller jacks. the large drop foot makes them super stable, and work well on the sandy soil in our area.
Best trailer jack i ever bought for our trailer smooth operating easy to weld in place.
Great product... It the Bulldog quality we always expect... Awesome..
All the products I have bought through etrailer have been awesome but above that their service is what sells me! Thanks for the great service and products!
Jack works great. Fast shipping.
Only thing I would change on this jack would be to shorten the the handle a bit.
Awesome jack, perfect for my trailer
Strong jack, heavy. Real easy to weld

This Jack is a monster. My trailer is very heavy, specially in the front. This jacks lifts the trailer with very little effort.
It works as expected
I still haven't received the product yet so it would be a 1 star review.

Works fine. As I mentioned, I disassembled it before welding it on.
