Specs:
A trailer jack is designed to lift the tongue of your trailer so you can connect the trailer coupler to your hitch ball. To do this, you'll need a jack with a lift capacity high enough to handle your trailer's tongue weight.
Tongue weight is the amount of weight that your trailer applies to the back of your tow vehicle. Typically, your tongue weight should be 10-15% of your total trailer weight (trailer + cargo). In other words, a 10,000-lb trailer would have a tongue weight between 1,000 lbs and 1,500 lbs. For a trailer this size, you would need a jack with a lift capacity of at least 1,500 lbs.
It's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher lift capacity should operate more efficiently, allowing you to spend less time cranking and more time camping.
Every jack offers a certain amount of lift or travel. Screw travel is the distance the jack extends when you crank it (or toggle it to "extend" on an electric model). Some jacks include a drop leg for extra adjustability. On these jacks, you'll see the maximum extension of the drop leg listed in the specs as well. Adding the screw travel and drop leg travel together will give you the total lift. The total lift listed above can help you determine how high this jack will be able to raise your trailer.

Today we're going to be taking a look at part number B-D-1-7-5-0-0-0. This is the Bulldog A-frame jack. The jack is a dependable jack, that's recognized as industry standard for agricultural and commercial applications. It's ASABE compliant. It's going to feature a static capacity of 7,000 pounds, with a lift capacity of 5,000 pounds. It's going to feature precision fitted parts. These are going to provide exceptional stability and reliability.
Here at the mounting location, this can be welded or bolted to mount to any standard a-frame coupler. The distance that we have between these mount holes, center on center, they are elongated, so they're going to fit your standard 3 mount hold pattern on your a-frame coupler. The distance that we have between those, center on center, is going to be 3 and 1/8 on an inch. That's going to be between each mounting hole. Your mounting hardware is not included. You could use your existing mounting hardware, or you need to pick some up, but the hardware is not included with the jack. Again, it can be welded or bolted to mount to any standard a-frame coupler.
It's going to feature a top wind handle. It's got a nice, smooth, ergonomic design for easy cranking. It's also going to feature an easy grip knob, that way it's going to ensure secure grip whenever you're operating the jack. The handle can be rotated to a stowed position, that way it's out of the way when it's not being used. The jack is going to be made from a steel construction. The outer tube is going to feature a gray paint finish.
Inner tube is going to feature a clear zinc coating. Real quick, I just want to give you the diameter measurement of the inner tube. That's going to give us a measurement of 2 inches. That means that outer tube is going to have a diameter of 2 and 1/4 of an inch. The footplate, or caster assembly for this jack is sold separately. It can be found right here at etrailer.com. With it in the fully retracted position, it's going to give us a bracket height measurement.
Measuring from the ground to the bracket, it's going to measure 12 and 1/4 of an inch. This jack provides 15 inches of lift, or 15 inches of travel. With it in the fully extended position, this measurement is going to increase to 27 and 1/4 of an inch. The distance that we have from the top of the bracket to the top of the jack, I am including up to this point right here. 13 and 3/4 of an inch. The top of that handle is going to sit an extra inch above, so that'd be 14 and 3/4 of an inch from the top of the bracket. Again, it's got a nice, smooth operating design. 15 inches of travel. Very easy to use. That's going to do it for today's look at part number B-D-1-7-5-0-0-0.

Strong lifting capacity, easier to crank than sidewinding designs.
Way better quality than the original jack that came with my trailer, if I ever need another one I'm definitely getting it from here.
Works great for what I need but odd that it does not have a foot hole to add base, a drill and its an easy fix.
Great product, as advertised
works much better than the bent one i took off
Just received it, have not put not on y et.
Great help & & the product turned out great also
worked as it should
Very nice jack stand, unfortunately I couldn't use do to not fitting. Fitment issue was on my end, my A frame is from another country and had none standard measurements. Customer service and return was great!
I have 10 trailers, I've been swapping out the OE jacks for these which lift much easier
I want to thank you guys for getting my trailer jack out to me before it was do,I sent before/after pictures to you,iam happy my trailer is happy.again thank you.
Solid product, smooth function, feels sturdy. BUT PLEASE NOTE: DOES NOT WORK WITH BullDog DROP LEG that is linked in related products. The diameter of tube listed for inner tube is 2”, and the BullDog BD 500377 drop leg lists outer diameter is as 1.75”…. However the two do NOT fit together. The inner tube measurement listed for the Jack is the OUTER diameter of the inner tube. Ignore the drop leg description that says it works with most manual trailer jacks. It doesnt work with this one, and I could find no bulldog manual trailer jack on the site that it will work with. Items individually seem fine, but are not compatible and are being returned.
I over loaded my work trailer broke the stock 2000lb trailer Jack. I needed a quick replacement and found your 5000lb Bulldog A-frame. The price was great and I got it in 4 days. It took less than 5 minutes to install and its such a better quality. It spins smooth and easy with just my finger. It's everything you say it is, I'm very pleased, thank you
This is a nice heavy trailer jack. I can't see anything going wrong with it.
Arrived on time me and as described
Although most trailers come with an A-Frame Jack, if I damage the jack or want to replace the bottom-of-the-line included jack, I prefer the Bulldog 5,000 lb jack. The jack is very stout, works effortlessly for as long as I've owned any trailer and never needs to be greased. In addition, it is designed to accept a flat foot attachment at the bottom or one of Bulldog's outstanding wheels.
