Video Transcript for etrailer Trailer Jack - Side Frame Mount Jack - MJSQ-2500B Review

Today we are going to be looking at a square jack that comes with a footplate and a drop-leg. This marine jack is going to let you raise or lower your boat or recreational trailer. It's going to feature a lift capacity of 2500 pounds. It is a bolt on installation with the included brackets and hardware. It's also going to feature a side-wined handle, it makes it really easy to raise and lower the jack. It's got nice smooth operation; I don't feel any kinking or binding. The handle radius measuring from the center of where the handle mounts to the outer edge of the hand-grip is going to measure about 7 and 7/8 of an inch.

The jack is made from a steel construction, and it's a square design. The outer tube, this is going to give us a width measurement of 2 and 1/4 inches. The inner tube is going to give us a width of 2 inches. The jack also features a clear zinc finish which is highly resistant towards rust and corrosion, and again, it does come with a drop-leg as well as a foot-plate. The footplate is welded to the bottom of the drop-leg. The footplates going to give us a width measurement of 3 and 3/4's, a length measurement of 7 and 1/2 inches, so it's a really nice design.

It's going to do a great job at spreading out the applied weight especially on softer ground to help prevent sinking. It also helps to increase over all stability, the drop-leg does come with a pin and clip that way you can hold it in position to whatever position you want to have the drop-leg extended or retracted at. I'm going to show you the drop leg. 00:01:45. This drop-leg features a five hole design, it's going to offer and additional travel of 13 and 1/2 inches. That's measuring from the center of outer hole to center of outer hole, 13 and 1/2 inches, and can be adjusted in increments of about 3 and 3/8's of an inch. Here on the inner-tube, you're going to notice a hole on each side; that way you can change the drop-leg to change the direction you want the footplate to be facing.

. Maintenance is going to be pretty easy with this jack. Located right here is going to be a built in zerk fitting so that way all you have to do is attach a grease gun, and you can pump in your grease to lubricate the internal components. This is designed to fit around trailer frames that have a frame height up to 5 inches, the trailer frame width must not exceed 3 inches wide. If we take a look at the mounting bracket dimensions, we are going to measure from outer edge to outer edge. .. Going this direction we're looking at 6 and 1/2 inches; top to bottom we are looking at 6 and 1/12 inches.

Now the bracket height with the jack in the fully retracted position, measuring from the bottom of the foot-plate to the center of the bracket, it's going to be about 7 and 1/4 inches. With that extended it increases to about 22 and 3/8 of an inch. The jack height, with it in the fully retracted position, that's going to measure about 24 and 3/4 of an inch. With the jack all the way extended it increases to 40 and 1/8 inches, so this jack is going to offer a travel of 15 and 3/8 of an inch, and then again the drop-leg is going to offer an additional 13 and 1/2 inches of travel. The clearance that we have from the center of the bracket to the top of the jack, that's going to give us a measurement of about 17 and 1/2 inches. That's going to do it for today's look at the square jack with the included foot-plate and drop-leg. Again it's going to have a lift capacity of 2500 pounds.

Sturdy, easy to install, and easy to operate. What more could you want in a trailer jack? I have purchased trailer hitches. bike racks, wiring harnesses, and now a trailer jack from a trailer. They have never let me down. 538696

Very well built and great for when a swivel jack cannot be used as in my case due to a tongue tool storage box. Superb seller communication with super fast shipping. Highly recommend!! 564947

Very nice looking Jack with the zinc coating , looks like it came factory from Legend , but it didn't. 410477

Great heavy duty jack, no signs of corrosion after a year of use, still works smoothly and is greaseable. It's used on a heavy triple axle boat trailer that's galvanized so its bolt on construction was convenient. 503876

I love it! I bought a used trailer for my 50 million pound pontoon ( OK, maybe 2500 lbs). The jack that came with it failed the fourth time I lifted it, and the tongue weight was so high that a concrete block I was using underneath shattered with the tongue resting on it. I replaced the broken concrete with a block of wood which is much better. The old jack also had a wheel which was utterly useless because of the trailer weight. This new jack installed easily and cranks smoothly and with almost no effort. Also has a grease zirc built in, but did not say how often to grease it. Very nice........... 581179

I purchased this tongue jack for my trailer last season. I trailer 4-6 days a week for 8months of the year. This product has exceeded my expectations in every way 408449

I used this for an unconventional application. It is clamped upside-down to the column of my floor drill press. This jack lets me raise and lower the heavy cast table of the drill press with a heavy cross slide fixture attached to it. No more back breaking and cursing when I need to adjust table height. I just had to drill 4 new holes in the mounting plate and use 4 clamp sections from 2 3/4" exhaust clamps with 5" 3/8 bolts to secure the jack to the drill press post. Simple modification made economical by etrailer.com. 401660


Comments

Still working GREAT! Uncommon application but it makes the drill press FAR more versatile! A little redneck engineering, but a big success!

Great square jack. Easy bolt on, smooth easy crank, adjustable height with the drop leg. Handles the tongue weight effortlessly. Has a grease fitting for lubrication. Fast easy bolt up install. 655007

by:

My old swing jack wasn't up to the task. It was difficult to wind and was binding under the weight. this square jack drop leg was just what I needed to handle my 5000 lb boat on a dual axel trailer. Installation was quick using the provided bolt up hardware. The jack is smooth and easy to turn. I particularly like the zerk fitting allowing periodic lubrication. The drop foot is very accommodating! I shopped a lot and found etrailer had the best selection, quality,and price. 655004

Rust is occurring at the foot as this is what ruined my last jack. The jack is still functional and in good shape. The part where the foot is attached slides and is detachable. It can be replaced. I will probably replace it at the 2 year mark 574953

My boat rests bow low on my trailer. I was looking for a bolt on trailer jack with 15 inches of travel and a drop leg. This product works great for my need.

It will be a while before I finish the trailer rebuild but this jack appears to be up to the task. It' seems to e very sturdy & well made.

I'll try yto report back in once it's been in use a while. 305984

  • Mounting Hole Size for A-Frame Trailer Jacks
  • The mounting hole dimensions of A-frame jacks are a standard 3 inches apart on center, so you will need to weld your new jack on. I highly recommend the Bulldog Round, A-Frame Jack # BD1700100317, which has a 5,000 lb capacity and will give you 15" of lift. It has an outer tube diameter of 2-1/4" and sidewind handle; for a footplate you would want # BD018564. This jack has been highly praised by our customers, with nearly 200 reviews it has an average close to 5 out of 5 stars. I've added...

  • Trailer Jack Recommendation for 3,000 lb Utility Trailer With 2-1/2" Tongue Width
  • For your utility trailer with a 2-1/2" wide tongue I recommend checking out the Square Jack w/ Footplate # MJSQ-2500B. This jack has a 7-1/4" bracket height when it is retracted and extends to 22-5/8", giving you 15-3/8" of travel. It has a 2,500 lb lift capacity, which is more than enough for a 3,000 lb trailer since the jack only lifts a portion of the trailer's weight.

  • Drop-Leg A-Frame Jack for 4500-lb Travel Trailer
  • The 2500-lb-rated Square Jack # MJSQ-2500B certainly has enough capacity to lift the 600-lb tongue weight (TW) of a 4500-lb travel trailer although this particular jack is primarily intended for marine trailer applications. This jack's included bracket mounts to the side of a trailer frame that measures up to 3-inches wide and between 2- and 5-inches tall. Since your travel trailer is an a-frame you might consider a comparably-rated a-frame jack like the 3000-lb-rated Bulldog # BD1550100317...
