Bulk control lines

McMaster-Carr lists type 302 and type 304 1X7 strand stainless cable. I can't see any difference in the descriptions, can someone tell me which one to use? The prices are the same, but I don't want to order the wrong stuff. Thanks.

Type 302—same corrosion resistance as 304, with slightly higher strength due to additional carbon.

For most practical purposes 302 and 304 are interchangeble.
The slight differences in strength can be overlapped from lot to lot of material.
In the distant past 302 was more intended for bar and rod stock and 304 was more readily available in sheet. That really isn't true anymore and for most aerospace applications they are specified interchangeably.

Thank you for the info.

While I know some to be buying line material from McMaster-Carr, I had less than stellar results the two times I did so, although I will admit they backed up their product in **fine** fashion the one time I complained.

I have since reverted to a tried-and-true source: SIG Mfg.

My trick, if one can call it that, is to buy 3-line sets and to select the 70-footers; lots of excess material to work with, never an issue with not enough material.

As a relatively minor bonus SIG is now supplying .018 line sets with the same kind of trick line connector a lot of us are making with Derek's clip-bending tool. Yeah, yeah, they are all the same size, but now that I am (finally!) cutting lines to a plus-or-minus 1/16" tolerance I have taken to using these relatively new SIG clips at the handle, my home-brew clips on leadouts.

I believe the clips mentioned above retail at $2.99 for four. They are (sorta) free with .018 line sets.
