Bank line is a black nylon cord/twine that is similar to tennis court netting. It’s exceptionally strong, UV resistant, and inexpensive.

It does pretty much everything paracord can do, but in a smaller diameter, so it's a lot lighter and takes up less room.

The name comes from trotline fishing (from the “bank” of a waterway, hence the name) for catfish or similar critters, where you toss out a strong main line baited with multiple hooks, and return hours later to check your line.

Bank line comes in a variety of diameters and strengths. The larger the number, the stronger the cord. Keep in mind what you want to use it for. If you're tying tie in loops on big wall gear, I'd go for the #12 cord. If you want to use it to build some kind of bushcraft shelter, you want something stronger.

Yes, the Amazon website where you buy this is pretty confusing. They sell different sized spools with apparently different weights, but it's a little hard to find how much length of cord is on each spool. I use these two numbers as a general guideline. I have a spool of each and they work great. You can get some other weights if you like.

#36 bank line has a breaking strength of about 320 pounds.
#12 bank line has a breaking strength of around 100 pounds, and is accordingly thinner and even lighter.

Popular in the survivalist / bushcraft world, bank line can be immensely handy around the house, garage, shop, or campsite.

Think lashing most anything, tent or tarp guy lines, clothesline, trellis for the garden, hanging a food bag, primitive shelter construction . . .

On a big wall, everything needs a way to be clipped in. Bank cord is perfect for making small clip in loops for most anything, and is less expensive than the bulk 2 or 3 mm cord normally used.

Bank cord is “tarred”, which is about what it sounds like. The cord has a thin layer of sticky tar-stuff. This helps knots to be more secure, makes the cord water resistant, and also resistant fraying at the ends when you cut it.

It has a mild petroleum-like smell, which goes away shortly after you open the bag. The stickiness is not annoying at all. It doesn’t come off on your fingers, just has a mild tacky feel to it. It's a little bit stiff when you first use it, but it loosens up a lot over time.
