What is the significance of the jacks being 4-pole/3-ring? How does this compare to other options?

Probably many uses for 4-pole plugs, also called TRRS plugs. But the current use is on Apple mobile devices that use one connection for microphone, and two connections for left & right stereo audio, and the last for common ground. You may enjoy reading Wikipedia "Phone_connector_(audio)". We bought it to extend a wired camera that came with this type of plug, even though it does not used all four connections.

I purchased 10 sets of these when Amazon had them on sale for a very low, low price. They all worked in all of my devices and turned out to be high quality. Therfore I am sure that they were 3.5mm jacks.

Two jacks in the package and a real good jack crank.The quality was much better than the jack that came with my camper ...Joe

I can't tell you how low they can go but what I can tell you is that at their lowest level they are too high for my Volvo but they do work at the level for my Van at that height. They would be great for a 4 wheel drive rig... They are a good strong jack so be okay with that but do use other back up blocks for your safety. If you are looking for ones for a car these are probably not for you!!!! ;o)>

Yah. The reason I got it was because it has a REN (Ring Equivalency Number of 5). You build / get a cable with a plug @ each end. One in in the SPA112, one in the phone wiring jack. As long as there is no more than an REN load of 5 on your in house phone system, you're golden. Old (really OLD) phones have an REN of 1. Newer phone have the REN on the base. Generally, with powered phones, that's a lot less than 1.

The jack has really good control for lowering vehicle. I really like this jack... I have a Allied 3-Ton I don't even use anymore.

Looks like it does right on the end. It has multiple jacks for some reasons but I do not have the instruction booklet on me.

it depends on what type of trailer you have. some trailers sit higher than others. it also depends on what type of ground level you are on, so the jacks will be leveled differently.you donot want to over extend the jacks . they cannot give you great stability fully extended. ,use blocks to give you better stability and this will be much easier to level out.

I have a pair of these and I love them. The jack is at a 45 degree angle (never saw that before). I use them with my computer, my LG smartphone and my Acer tablet. All work the same. For the best sound, follow the suggestion for burning in the drivers.

Sorry, I don't know what a line out jack is. I would think this is listed in the section of product details. Karen

I've used Bosch plats in three vehicles in my years, two were single electrodes, my current has the four type, and in all cases I saw good results. I got the four type this time due to great price and rebate. I've never had to regap them even after checking. If you find the four type at a good price, I'd get them. If price is an issue, the singles are fine too.

These are not made for that. The jack has plenty of power. You would have to make mounts for them and it could be major. If you are handy and have the tools it might work. Go to an RV place and see what is on an RV that has levelers and see if you could do something similar with 4 of these jacks. If it works great but if not it is an expensive experiment. Count the cost. Good luck?

The main Torin page (www.torinjacksusa.com) is not much more help than the description here on Amazon for your particular question but there is a warning on each jack stand as well as in the Operators Manual that comes in the box and they both say (along with other warnings) that the stands are only to be used as a matched pair so my assumption would have to be that the stands are rated to hold 3 tons together as a pair and not individually.

two ring and three ring are different, but they should still work. the third ring/connector is for a microphone. that extra ring/connector gets used for a lot of different things, but if you're just using headphones, it shouldn't make a bit of difference. the two rings are for stereo, so this will work fine with your headphones.

I'm not sure if it is or not. There seems to be other manufacturers that make the same jack. But I do know that I like mine!

i don't know what you mean by 3 ring adaptor... there are 2 channels for stereo sound and one for mic... BTW it is a poorly made product

This unit comes with four adapter jacks, and it may be possible, but you would have to take the jack set with you to the store and try them to see if the results are satisfactory for your purpose.
