I was inspecting some climbing gear and this rope was mixed in.  I was told it is a static rope for climbing.  I cut off one end to look for a tracer, none found.  But I noticed that the kern did not have any kind of twist to it.  I have never cut into a climbing/rescue rope, used for climbing, that did not have twists in the kern.

It is also very thick in diameter, 13mm or 1/2 inch.  It would have been new in 2018 or 2019.  Here is a picture.  Does anybody know the manufacturer?  Are there static ropes that do not have a twisted kern?

Some kind of arborists rope maybe?

Yes, there are static ropes without twisted cables in the core. It is an american-style static rope. The core fibers are straight and not spun or twisted into the spring-like cables you see in dynamic ropes. Many polyester static ropes are made with straight core fibers as shown in your photo. You get a rope with very low stretch using this straight core construction technique. The technique can also save costs in production since less machine time is needed to make the rope.

No arborists ropes have the unilateral parallel core strands, I’ve only seen Sta-Set X, a marine rope with that type of core.  Most static ropes have twisted parallel strands, a few use a hollow braid core.

Thanks for the responses!  I still don't have it figured out.  I did contact New England ropes and they said it was not one of theirs.

The search continues.

Reminds me of a Teufelberger pattern. That's nearly worthless as a data point, but there it is

New England = Maxim = Teufelberger   they are all the same

Does this rope have a gauze like material wrapping the core strands together, like the Sta-Set X?

There is no gauze type material wrapping the core.  I do have another email out to the company it may have been bought from, to see if they can identify it.

I don't recognize it, It is definitely not KMIII.

Dynamic ropes generally have twisted Kern strands (That's what gives the stretch) Whereas static ropes will tend to have straight or braided cores.

Other specialty rope users to probe:

Arborists

Yaughting / Marine

Rope Courses

1/2" or 13mm would indicate industrial, more than recreational use.

It could be for caving. But I don’t know enough, just another use for a static rope I hadn’t seen mentioned yet.

Perhaps a cheaper rope that has most of the strength coming from the cover, the core might just be a filler, perhaps polypropylene.  Does it cut easy, dyneema doesn’t.  Melting and smelling, if you know the difference, could tell what type of materials. 

Guideline #1: Don't be a jerk.
