What is a link spring?

It's the spring and hardware that holds up the mattress...all that comes with this set is just the frame.

It is a quick link, but I never use it. I measure the old chain length and punch out the pin at the needed length avoiding the quick connector

I am not sure what spring is in it but this is designed as a direct OEM replacement. I am at 17.5PSI with no issue whatsoever.

There's one firing pin spring,one trigger spring that you don't have to use and two springs for your safety plunger/extractor. It's awesome and easy to install

Yes, although I haven't actually used the expansion links so can't speak to how easy they are to attach. The quick release works very well.

Yes it does come with the link wire. The link wire connects to one caliper arm and then to the main cable from the lever at a clamping bolt. The main cable from the lever then runs on to the other caliper arm. This allows flexible adjustment because both the clamp connecting the two cables and the clamp for the main cable at the caliper arm can be adjusted.

I have found that even if the hook of the spring doesn't provide enough tension, you can always just use a spring coil further down. I've had to do that many times on a basement remodel.

You simply push down on the little metal "fin" in back, or up on the one in front -- After putting a little effort to move it, a spring assist will switch it open for you. Very simple and user friendly!

Yes it has the spring. It is ready to be installed right out of the package. It has a solid feel and performs well.

Yes. It is NO (normally open) switch. Push to close. Spring returns it to NO.

This is spring based but it locks when it is fully expanded. Red button in the middle actually pushes in when device is placed on it and it snaps to fit accordingly.

I think that it refers to the spring tension or SIZE of the return spring. I have mine on a solid core wood door that is between my laundry room and garage. The tension works fine on my door. With the main garage door open, there is a lot of airflow and this closer handles it.

Because of the characteristics of the springs, diameter, k, length, I would be hesitant to use anything but OEM replacements to assure it continues to operate correctly. If you feel lucky you can grab all of the data, wire diameter, length at rest, stretched length and force required to stretch, hook end dimensions, etc. and go to an industrial supply store. You may find you will have to cut to length, apply heat to bend the ends and properly quench. I've made springs for other devices in this manner and would return to the OEM if possible just to save the PITA factor.

The spring tension is adjustable. I used it on a gate and it was installed on the outside of the gate.

yes. if you just want it to open or close based on temperature. The spring in it is temperature sensitive and will open or close by itself when temperature is lower.

There are no springs. It's a simple butterfly screw and threaded metal rod setup. The only way to adjust the distance between the plates to press the Tofu harder is to shorten the distance between plates by tightening the screws.
