3/8 in. Black UV-resistant durable rope (to replace white cotton laundry rope)?

While it is not black, it is UV-durable. ‘Silver’ float rope, from boat shops or large hardware shops.

Cheers

Thanks Roger, I’m familiar with float rope, but wasn’t aware it came in silver. Alas, I’ve got to find a black, olive drab or dark charcoal rope – a color that will blend in with the green background of the garden (literally green = an ivy wall and lots of perennial flowers and green shrubs + a dark gray wood fence). I can’t bear to put a “loud” thick white rope there.

Coloured may be more difficult. I suspect the ‘silver’ appearance is part of the UV-blocking treatment. A dark green or a black colour would be more likely to absorb the UV.

Cheers

Look for a polyester rope.  Marlow makes a doublebraid that’s overkill for laundry line but available in 8 or 10mm, black, with great UV resistance, lower stretch, and splice-able so no knots to pass through your pulleys. I’m sure there are others also on the market from other manufacturers.

Thank you for the suggestion. I was thinking polyester for the UV resistance but didn’t know a specific brand or model. I’ll check them out. There are a bunch of black polyester ropes available on Amazon – do you think it’s safe to assume most will be UV resistant? It will be interesting to see how the black line holds its color in the sun, rain and winter cold.

There are 12 different stoves all advertised as “BRS-3000T” on Amazon. Only one of them is genuine. All the rest are either dodgy fakes or crappy fakes.
If that is the sort of quality control you get on Amazon, should you trust ANY of the black PE ropes?
Yeah, I am either suspicious or paranoid. But I am still alive.

Cheers

Agree with Roger on Amazon sourced quality or authenticity often being in question.  It’s line for hanging laundry, so not life threatening, but sticking with a quality manufacturer through reputable sources avoids headaches and reduces the amount of “stuff” that ends up in the trash.

Says it is uv resistant.  Perhaps they have a larger size but breaking strength suggests it might do the job for you.

Have you considered 3/8″ Amsteel? Dutchware offers in several colors including black >> (Black 3/8″ Amsteel)

….AAND with an average breaking strength of 19,600lbs, it would almost be suitable :)

Thank you. I was about to order 3/8 (10mm) marine double braid black line, which is pretty strong too, though not that strong. Marine line should be highly UV- and rot-resistant. Will the Amsteel be as UV- and rot-resistant?

Yes absolutely, it’s designed for the marine and commercial industrial environment. Link to [Samson Website]

Thank you. Do you think the Amsteel will be as colorfast as the marine polyester double braid? I don’t mind if it fades a bit to charcoal, so long as it doesn’t quickly become a…white laundry line LoL.

Well, I’m not here to steer the boat. Both are overkill for what you’re doing, I would go with the Poly if it’s less expensive and it undoubtedly is. I’m assuming you’re going to be splicing the ends together? How well does the double braid splice?

If you think they are equally colorfast, I’ll get whichever is least expensive. The ends go into a metal thingamajig, which holds each end and allows you to screw them closer together to tighten the line.
