Excellent product! Installs very easy and seems very durable. Smooth operation jack! 341980

Jacks arrived in great shape, and very quickly I may add. They are very sturdy and will be way more than enough for the installation they are intended for. They will be installed on a support outrigger for a stair/working platform. 428296

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

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

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

My Square Jack / Ram Jack, lasted from April 2013 – about April 2019 I purchased a 2013 inshore Sundance DX22, the trailer came with a 2500 lb Ram Jack, that jack lasted till 2019 that’s around six years. I then came to etrailer.com to purchase a MJSQ-2500B Square Jack which is made by Ram Jack and is the same jack that came with my trailer. my Ram jack was a 2013 (looked identical) to the etrailer Square jack that I ordered (see pics), the jack lasted till 2019 before the bottom rusted enough so that the shaft on the inside would not extend out or retract inward. I live in Florida near the salt water, and launch in salt water all year round, so the jack does get salt spray and salt mist on it all the time, and sometimes the bottom of the jack is in the salt water, depending on the tide at the ramps. Having had boats all my life, six years is a long time for a jack to last in salt water environment. Just to give you an idea of my saltwater environment, my Dodge Ram 3500 bumper and tail pipe rusted out before my jack did (see pics) Not saying that this is normal or not, just that this was my experience with my Ram jack. Hope my new Ram jack lasts as long. Pics show it mounted, I decided to spray some zinc galvanized paint on the bottom of the jack, just for a little added protection., As far as etrailer goes, from time to time I order parts from them, they never disappoint. Thanks etrailer for my replacement Ram jack. 705674

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

Good quality and easy installation on my boat trailer. Also bought a square-tube 6" caster/wheel accessory -- from another company -- to use (instead of the drop-leg foot plate) when moving the trailer on the concrete floor of my shed. 784492

Product is great, very well constructed all for a great price. This was a fantastic company / site to work with. I got emails updating me on shipping, tracking, and follow up after the order. The emails come from real people, not just automated "no reply" updates. My order shipped the same day I ordered, and was upgraded to expedited shipping for no additional charge! I received a personal email letting me know about this. The item was packaged very well and I cannot recommend this company enough. Great buying experience! 748843
